Where to Buy CJC-1295/Ipamorelin in 2026: 10 Research Suppliers Compared
Researchers and labs searching for CJC-1295 and Ipamorelin blend for sale in 2026 run into dozens of suppliers, but not all are the same. Third-party testing, quality, and pricing all differ. Across the ten US research suppliers compared here, the blend ranges from $6.25 to $14.50 per milligram of total peptide.
We analyzed more than 30 research vendors in the USA and narrowed the field to 10. A supplier appears here only if it sells the blend at a verifiable public price, publishes a certificate readable before purchase without an account, and ships domestically. Rankings then turn on what each certificate documents: whether it names the laboratory that ran the analysis, how many tests it covers, and whether it accounts for both peptides. Three of the ten name no laboratory anywhere, and a fourth names one only in site copy.

CJC-1295/Ipamorelin Blend for Sale: Top Vendor Comparison for 2026
Protide Health ranks first among the ten CJC-1295/Ipamorelin research peptide suppliers compared here. Its certificates are issued by Freedom Diagnostics, a named US laboratory appearing on the certificate document itself, and the latest 5mg/5mg panel runs seven separate analyses: identity by LC-MS, purity by HPLC-UV, net peptide content, bacterial endotoxin by Limulus Amebocyte Lysate assay under USP <85>, PCR microbial screening, elemental impurities by ICP-MS covering arsenic, cadmium, lead and mercury, and a fentanyl screen. No other certificate reviewed for this guide covers more than four of those seven. Net content is also reported per vial and broken out separately for each of the two peptides in the blend, a disclosure almost nobody in this category makes. Certificates sit in a public library with no account required. At $125.00 for the 10mg/10mg vial, or $6.25 per milligram of total peptide, it is also the lowest cost per milligram of the ten suppliers compared here.
Oath Research ranks second for running a Freedom Diagnostics panel with the most recent certificate dates in the group. Onyx Biolabs ranks third as the only other supplier here publishing elemental impurity screening, alongside a per-component blend analysis that independently confirms the fill weight of each peptide.

What the CJC-1295/Ipamorelin Blend Actually Contains
The CJC-1295/Ipamorelin blend is two chemically distinct synthetic peptides supplied together in one lyophilized vial. It is not a single compound, and the two molecules have nothing structurally in common.

Two Compounds in One Vial
CJC-1295 without DAC is a synthetic 29-amino-acid analogue of growth hormone releasing hormone, also catalogued and sold as Modified GRF 1-29. It carries CAS number 863288-34-0 and is indexed in PubChem as CID 91976842 with the formula C152H252N44O42 and a molecular weight of 3,367.9 g/mol. Ipamorelin is a pentapeptide, a five-amino-acid chain with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2, CAS number 170851-70-4, indexed in PubChem as CID 9831659 with the formula C38H49N9O5 and a molecular weight of 711.86 g/mol.
Reading the Ratio: 5/5mg vs 10/10mg
A vial labeled 5mg/5mg contains 10mg of total peptide. A vial labeled 10mg/10mg contains 20mg. But some suppliers label by total content instead, so a listing reading “10mg blend” may mean 5mg of each peptide rather than 10mg of each. Separately, some listings sold as a “blend” are not one vial at all. Confirm total milligrams and vial count before comparing any two prices.
The 10 Best Places to Buy CJC-1295/Ipamorelin in 2026
Each entry below states what the supplier publicly documents and what it does not. Where a supplier makes a claim its own published materials do not support, that gap is noted.
1. Protide Health
Best for: Researchers who want the widest analytical panel in the category, a named testing laboratory, and lowest per-mg pricing

Protide Health is a US-based research peptide supplier carrying more than 50 compounds, and it ranks first here because its certificates document more testing, in more detail, than any other supplier in this comparison. The CJC-1295/Ipamorelin blend is offered in 5mg/5mg and 10mg/10mg single combined lyophilized vials in 3mL sterile glass, at $75.00 and $125.00 respectively as of August 2026.
Analysis is performed by Freedom Diagnostics, a US-owned and operated laboratory named on the certificate document itself and signed by its principal chemist, not referenced generically in marketing copy. That distinction separates Protide from much of this field, since four of the ten suppliers here either never name a laboratory or name one only in site copy the certificate does not corroborate. Certificates sit in a public COA library and test results archive, organized by lot with distinct accession numbers and a searchable verification code, readable with no account.
The current 5mg/5mg CJC-1295 No DAC and Ipamorelin blend certificate is the most thorough document reviewed for this comparison. Lot PH-c/i55-0605, accession number 2607230265, received July 23 and reported July 27, 2026, runs seven distinct analyses rather than the one or two most suppliers report. Identity was confirmed for both compounds by LC-MS. Purity returned 99.82 percent by HPLC-UV on two vials assayed independently rather than one composite sample. Net peptide content was measured per vial and split by compound, averaging 6.81mg and 5.83mg. Both endotoxin replicates passed by Limulus Amebocyte Lysate assay under USP <85> at an assay sensitivity of 0.05 EU/mL or lower. A validated polymerase chain reaction assay returned no detectable microbial DNA. Elemental impurities were screened by ICP-MS, meaning inductively coupled plasma mass spectrometry, with arsenic, cadmium, lead, and mercury all below reporting limits. The certificate additionally records a fentanyl screen returning no fentanyl detected, which no other supplier in this comparison publishes.
The document also reproduces the chromatogram and the mass confirmation spectra as raw supporting data rather than a summary figure, so the Ipamorelin and CJC-1295 peaks and their mass confirmations can be inspected directly. The 10mg/10mg certificate, lot PH-c/i1010-0327, accession 2605060073, reports 99.93 percent.
- Pricing: 5mg/5mg at $75.00 and 10mg/10mg at $125.00 as of August 2026, working out to $7.50 and $6.25 per milligram of total peptide, the lowest per-milligram figure in this comparison
- Testing performed by Freedom Diagnostics, named on the certificate itself and signed by its principal chemist
- Seven-part panel: LC-MS identity, HPLC-UV purity, net peptide content, USP <85> endotoxin by Limulus Amebocyte Lysate assay, PCR microbial screening, ICP-MS elemental impurities covering arsenic, cadmium, lead and mercury, and a fentanyl screen
- The only supplier in this comparison publishing a fentanyl screen, and one of two publishing an elemental impurities panel
- Net content broken out separately for CJC-1295 and Ipamorelin, which very few certificates in this category do
- Dispatch within 24 hours from a US facility with 2 to 3 business day domestic delivery
- Free shipping applies over $199

2. Oath Research
Best for: Researchers who want an equivalent named-laboratory panel with unambiguous total-milligram labeling.
Oath Research ships from Gilbert, Arizona and publishes Freedom Diagnostics certificates with the laboratory identified inside the PDF rather than only in site copy. Its panel includes: LC-MS identity, HPLC-UV purity, net content split by peptide, and USP <85> endotoxin at an assay sensitivity of 0.05 EU/mL or lower. Labeling is clear, stating “CJC-1295 no DAC: 5mg,” “Ipamorelin: 5mg,” “Total Peptide: 10mg,” and “Ratio: 1:1 Equal blend” on the page itself.
One documentation problem keeps it from ranking first. The certificate widget surfaces the 10mg/10mg certificate by default while the page copy describes the 10mg-total product, so the default view shows a certificate for a different size. That widget also displays an endotoxin badge, while the certificate behind it contains no endotoxin section and notes only that other batches have been endotoxin tested.
- Pricing: $90.00 for the 10mg-total vial and $150.00 for the 20mg-total vial as of August 2026, or $9.00 and $7.50 per milligram
- Freedom Diagnostics named inside the certificate document
- Batch B2826075 reported 99.80 percent and batch B2826030 reported 99.92 percent, both tested July 22, 2026, the most recent certificate dates in this comparison
- Single co-lyophilized vial, with contents and total peptide stated explicitly on the page
- Free shipping over $250. No dispatch cutoff time is published
3. Onyx Biolabs
Best for: Researchers who want per-component fill verification and heavy metal screening.
Onyx Biolabs operates from Charlotte, North Carolina and publishes the second most analytically varied certificate in this comparison. Report KVR-2026-5C15AF for batch CJCIPA-26072A, certified July 3, 2026, gives a batch average of 99.639 percent by RP-HPLC with diode array detection at 214nm, LC-MS blend identification, an endotoxin screen, and a four-element heavy metal panel covering arsenic, cadmium, lead, and mercury, all negative. Only Protide Health also screens for elemental impurities. A blend component analysis reports Ipamorelin at 5.83mg and CJC-1295 at 5.71mg against a 5mg label for each, independently confirming the stated 10mg total.
It does not rank higher because of an independence question the site raises about itself. The laboratory named on the certificate is Kovera Labs, and Onyx’s own banner advertises a “Verified Kovera Logistics Network,” using the same brand name for its logistics operation that appears on its purportedly independent certificates.
- Pricing: $80.00 list, discounted to $64.99 as of August 2026, or $8.00 and $6.50 per milligram of total peptide
- Kovera Labs named inside the certificate, with a published verification code
- Per-vial purity and net content reported for two vials, plus per-component fill weights
- Labeling states “a 1:1 ratio (5mg/5mg) for a total of 10mg”
- Free shipping over $200. Product page advertises same-day dispatch by 2PM EST while the shipping policy states 24 to 48 hour processing and warns of current delays
4. Simple Peptide
Best for: Researchers who want a broad analytical panel and can resolve the labeling question with the company first.
Simple Peptide, based in Delray Beach, Florida, publishes the most complete test panel of any supplier here. Accession 2605270348, lot IPCJ20-052026-4, reported May 29, 2026, covers LC-MS identity, HPLC-UV purity at 99.89 percent, net content, USP <85> endotoxin, and a validated PCR-based microbial screen. Freedom Diagnostics is named inside the certificate, though nowhere in the site’s own copy.
It ranks fourth because a buyer cannot determine what they are buying. The SKU reads IPCJ-PW-5MG-5MG and the imagery says 5MG/5MG, while the linked certificate is headed 10mg/10mg and reports 11.27mg Ipamorelin and 11.19mg CJC-1295, roughly 22.5mg total. At $65.00 the product is either $6.50 or $2.89 per milligram depending on which of the company’s own figures is correct. The page also transcribes its own certificate incorrectly, listing lot IPCI20-052026-4 against the certificate’s IPCJ20-052026-4 and a date of June 4, 2026 appearing nowhere in the document.
- Pricing: $65.00 as of August 2026. Cost per milligram cannot be stated with confidence until the labeling is resolved
- Freedom Diagnostics named inside the certificate but never in site copy
- One of only two suppliers here pairing PCR microbial screening with endotoxin testing on the blend
- No free shipping threshold is published anywhere on the site, and three conflicting dispatch cutoffs appear across the homepage, banner, and FAQ
5. Ascension Peptides
Best for: Researchers who want per-peptide mass confirmation and a named analyst on the certificate.
Ascension Peptides publishes MZ Biolabs certificates carrying the laboratory address in Tucson, Arizona and the analyst named inside the PDF. Method is stated as HPLC-UV-MS, with identity confirmed separately for each peptide against expected mass. Lot 59-03260429, analyzed March 20, 2026, reports 99.61 percent overall purity with Ipamorelin measured at 13.14mg and CJC-1295 at 10.77mg per vial against a 10mg/10mg label. The prior lot reported 99.86 percent with Ipamorelin at 12.73mg. Publishing a measured overage of that size is unusual transparency, and it is also a reason to read the certificate rather than the label.
Two things hold it back. The 20mg product is currently out of stock, and the product page carries no advertised purity figure at all to check the certificate against. Ascension also runs continuous promotional pricing, with essentially every SKU showing a strikethrough list price, so the figure a visitor sees depends on timing. This comparison uses the list price.
- Pricing: $199.99 list for the 20mg vial and $99.99 for the 10mg vial as of August 2026, both $10.00 per milligram. Promotional pricing at the time of checking was substantially lower
- MZ Biolabs named in site copy and inside the certificate, with a named analyst
- Separate mass identity confirmation and measured quantity for each peptide
- Product copy states the with-DAC formula and molecular weight for a no-DAC product, contradicting the certificate on the same page
- Product badge advertises free shipping over $250 while the shipping policy states a flat $15 domestic rate with no free tier
6. Core Peptides
Best for: Researchers who want an accreditation number they can independently look up.
Core Peptides operates from Orlando, Florida and is the only supplier here whose certificate carries a specific accreditation reference. The document names Vanguard Laboratory of Olympia, Washington, gives its street address and phone number, names both the reporting director and the approving operations manager, and cites A2LA Certificate 6377.01.01. Labeling is clear, stating “Size: 10mg” and “Contents: CJC-1295 NO DAC (5mg) & Ipamorelin (5mg).”
Two gaps push it to sixth. The panel is a single method, chromatographic purity by HPLC-UV/VIS, with no mass spectrometry identity confirmation, no net content, no endotoxin, and no microbial screening. And the certificate matching this product, lot C73453 reported April 2, 2026, reads 98.84 percent with a stated tolerance of 0.18 percent against a product page advertising purity above 99 percent. Even at the top of that tolerance the certificate does not reach the advertised floor.
- Pricing: $80.00 as of August 2026, or $8.00 per milligram of total peptide
- Vanguard Laboratory named inside the certificate with an A2LA certificate number, though Vanguard is not named anywhere in Core’s own site copy
- Single-method testing: HPLC-UV/VIS purity only
- Published certificate reports 98.84 percent against an advertised threshold above 99 percent
- Free shipping over $200, same business day dispatch before 1PM PST
7. Biotech Peptides
Best for: Researchers who want open per-lot certificates and can accept unattributed testing.
Biotech Peptides operates from Las Vegas, Nevada and publishes per-lot certificate images directly on the product page with no registration required. Its certificate assets were uploaded in April 2026, more recent than the January 2026 documents the company carried earlier in the year. The product is explicitly the no-DAC form, stated as “Note: DOES NOT CONTAIN DAC.”
It ranks seventh on two unresolved gaps. The testing laboratory is not named on the product page, the About page, or the certificates, which carry only a Biotech Peptides watermark, so the third-party testing described in site copy cannot be attributed to anyone. And the listing reads “CJC-1295 & Ipamorelin Blend (10mg)” without stating whether that is 10mg total or 10mg of each, which makes the per-milligram figure below provisional.
- Pricing: $81.00 as of August 2026, or $8.10 per milligram if the 10mg figure is total peptide
- Testing laboratory not named on the site or on the certificates
- Methods described in site copy as HPLC and mass spectrometry, with no endotoxin or microbial screening mentioned
- The no-DAC product page carries a half-life description belonging to the with-DAC form
- Free USPS Priority shipping over $200. Product page states a 12PM PST cutoff while the shipping page states 1PM PST
8. BioLongevity Labs
Best for: Researchers who want depth of certificate history without a login.
BioLongevity Labs operates from Akron, Ohio under F2 Nutrition LLC and publishes 18 certificate images for this product in a tab requiring no account, which is genuine depth. Labeling is unambiguous, stating “This is a (10mg) blend each of CJC-1295 (No DAC) (5mg) and Ipamorelin (5mg),” and the newest uploads are dated May 2026 across three lots.
Its ranking reflects a claim the site does not support. BioLongevity states it is the only research peptide supplier verifying every batch through three separate certified laboratories, yet none of those three is named on the product page, the certificate index, or the About page. Its list price also sits against a standing 50 percent site-wide promotion, so the advertised and checkout figures diverge substantially and the effective price depends on timing.
- Pricing: $99.97 list as of August 2026, or $10.00 per milligram of total peptide, discounted to $49.99 under an active site-wide promotion at the time of checking
- No testing laboratory named, despite a claim of three separate certified laboratories
- Older lots show evidence of separate per-peptide certificates, while 2026 documents are combined
- The no-DAC product description characterizes the compound as binding endogenous albumin, which describes the with-DAC form
- Free shipping over $400, the highest threshold in this comparison. Same-day dispatch before 12PM PT
9. American Peptides
Best for: Researchers who want lot-matched certificate PDFs attached directly to the listing.
American Peptides, based in Shreveport, Louisiana, links four documents from the product page, including separate lot-matched certificates for the 5mg/5mg and 10mg/10mg presentations plus a 16-section GHS safety data sheet, all opening without an account. Attaching a distinct certificate to each size is better practice than the single catalog-wide document several competitors use.
It ranks ninth because almost nothing in those documents can be read. The certificate PDFs are image-only with no text layer, yielding no laboratory name, no test date, no purity figure, and no method statement, and the site names no laboratory in its own copy either. The product page contradicts itself on purity, with a bullet claiming 99.9 percent against a specifications block stating 99 percent or higher, and neither figure can be checked against the certificate. The 10mg/10mg variant is sold out with no price published anywhere on the domain.
- Pricing: $90.00 for the 5mg/5mg vial as of August 2026, or $9.00 per milligram. The 10mg/10mg price is not published
- No testing laboratory named in site copy, and none readable inside the certificates
- Certificate date, purity figure, and methods are all unverifiable from the published documents
- Vial count is stated only on the parent collection page, never on the product page
- Free shipping over $300. Three different dispatch cutoffs appear across the banner, product page, and shipping policy
10. Sports Technology Labs
Best for: Researchers specifically seeking the DAC form who want two compounds supplied separately.
Sports Technology Labs, headquartered in Shelton, Connecticut, publishes the most specific regulatory disclosure of any supplier here, naming MZ Biolabs of Tucson, Arizona and citing a DEA Schedule III license number. Certificates are public with no login.
It ranks last for three reasons, and the first two mean it is not directly comparable to the other nine listings. Its product is CJC-1295 with DAC rather than the no-DAC form every other supplier here sells, and it ships as two separate 5mg vials, confirmed three times on the page in body copy, specifications, and image alt text. Its certificates are 13 and 16 months old while captioned as the most recent batch documents.
The page also carries a chemistry contradiction. The CJC-1295 DAC page, served at the /product/cjc-1295-peptide/ URL by redirect, lists CAS 863288-34-0, formula C152H252N44O42, and molar mass 3367.9 g/mol, which are the no-DAC specifications confirmed above against PubChem, while stating a half-life of roughly 6 to 8 days and describing a 30-amino-acid DAC-conjugated analogue. The identifiers and the description cannot both be right.
- Pricing: $144.99 list, discounted to $128.99 as of August 2026, or $14.50 and $12.90 per milligram, the most expensive listing here either way
- Two separate 5mg vials rather than one combined vial, and the DAC form rather than no-DAC
- MZ Biolabs named in site copy, with certificates published as images
- Certificates dated 07/03/25 at 98.96 percent and 03/31/25 at 99.74 percent, the first falling below the 99 percent minimum stated elsewhere on the same page
- Free shipping over $149, the lowest threshold here. No dispatch cutoff time published
How to Choose Where to Buy CJC-1295/Ipamorelin
Choosing where to buy CJC-1295/Ipamorelin comes down to what a supplier will document rather than what it will claim, and to normalizing prices that are not presented in comparable units. The five checks below separate suppliers that can support their claims from suppliers that only state them.

Cost Per Milligram of Total Peptide
Divide the price by the total milligrams of peptide in the vial before comparing anything. Nothing else in this category produces a comparable number, because the products are sold in two sizes under two labeling conventions and occasionally in two vials. Ranked ascending, the ten suppliers land as follows.

List prices verified August 9, 2026. Several suppliers were running promotions at the time of checking; list prices are used throughout for comparability.
Read that table alongside the documentation column in the main comparison, because paying more does not buy more paperwork. The most expensive entry, at more than double the cheapest, publishes certificates over a year old for a different chemical form of the compound. Three of the four suppliers in the $9.00 to $10.00 band either name no laboratory at all or publish certificates whose purity figures cannot be read. Meanwhile the two cheapest entries, Protide Health at $6.25 and Simple Peptide at $6.50, both publish Freedom Diagnostics certificates naming the laboratory inside the document. Price and documentation quality are close to uncorrelated in this category, which is why both have to be checked separately.
Buying the two peptides separately is the other comparison worth running, and it usually loses. At Protide Health, standalone CJC-1295 No DAC 10mg is $75.00 and standalone Ipamorelin 10mg is $75.00, so assembling 10mg of each costs $150.00 against $125.00 for the combined vial. That is $7.50 per milligram separately versus $6.25 combined, plus two certificates to reconcile instead of one.
Per-Batch Certificates, Not Catalog-Wide Claims
A supplier advertising 99 percent purity across an entire catalog is describing a target, not a measurement. A per-batch certificate reports what one specific production run actually tested at, identified by lot number and date. Look for a named lot, a distinct certificate number, and a recent reporting date, and check that the certificate on the page is the newest the company holds. Sports Technology Labs captions certificates from March and July 2025 as its most recent batch documents, which is the kind of gap that only surfaces if you look at the date rather than the label. For a fuller breakdown of the fields a certificate should carry, see what a peptide certificate of analysis shows.
Two Testing Methods (At a Minimum)
HPLC measures purity, meaning how much of a sample is a single compound. Mass spectrometry confirms identity, meaning whether that compound is the one on the label. A supplier reporting only HPLC has documented that a sample is clean without documenting what it is. Core Peptides is the clearest example here, reporting chromatographic purity by HPLC-UV/VIS with no identity confirmation. Endotoxin testing under USP <85>, PCR microbial screening, elemental impurity panels by ICP-MS, and contaminant screening are additional signals few suppliers publish, and the gap between the top and bottom of this field is wide. Protide Health’s certificate reports all four alongside identity, purity and net content, Onyx Biolabs reports two of them, and four of the ten suppliers here publish none.
Certificates You Can Read Before You Buy
Documentation that cannot be inspected before purchase cannot inform the purchase decision. All ten suppliers in this comparison publish certificates without an account, which is why they are here. Outside this list the picture is different: several established suppliers in this category place either pricing or certificate archives behind account registration, and at least one now operates its entire storefront on a members-only basis. Treat open certificates as a meaningful differentiator. Note also that a certificate published as an image with no text layer is only partly open, since its contents cannot be searched, indexed, or verified quickly. American Peptides, Biotech Peptides, BioLongevity Labs, and Sports Technology Labs all publish image-only documents.

Internal Consistency and Documentation Continuity
Contradictions across a supplier’s own site are a signal in their own right, and this category is full of them. Ascension Peptides publishes the with-DAC formula in the description of a no-DAC product whose certificate on the same page states the correct no-DAC mass. BioLongevity Labs describes albumin binding, a with-DAC characteristic, on a no-DAC page. Sports Technology Labs lists no-DAC identifiers against a with-DAC half-life. Simple Peptide transcribes its own lot number and certificate date incorrectly. Core Peptides advertises above 99 percent and publishes 98.84 percent. Several state two or three different dispatch cutoffs across their own pages. None is fatal alone, but loose internal process tends to reach documentation eventually, which is the same reason a comparison like where to buy BPC-157 found three of nine suppliers advertising a purity threshold their own certificates did not meet.
Frequently Asked Questions
Where can you buy the best quality CJC-1295/Ipamorelin blend?
For 2026, Protide Health ranks first among the ten suppliers of the CJC-1295/Ipamorelin blend compared here, for three specific reasons. It names Freedom Diagnostics on the certificate document itself rather than only in marketing copy, signed by the laboratory’s principal chemist. It latest 5mg/5mg batch runs a seven-part panel covering LC-MS identity, HPLC-UV purity, net peptide content, USP <85> endotoxin testing, PCR microbial screening, ICP-MS elemental impurities, and a fentanyl screen, with two vials assayed independently per lot and net content reported separately for each of the two peptides. No other certificate reviewed for this guide covers more than four of those seven. And at $6.25 per milligram of total peptide for the 10mg/10mg vial, it is the lowest cost per milligram in this comparison.
How much does the CJC-1295/Ipamorelin blend cost?
Across the ten suppliers compared here, list prices in August 2026 ran from $65.00 to $199.99 per vial, normalizing to $6.25 to $14.50 per milligram of total peptide. Sticker prices are not comparable for three reasons. First, the blend ships in two sizes, 5mg/5mg for 10mg of total peptide and 10mg/10mg for 20mg, and the larger vial is almost always cheaper per milligram. Second, suppliers use two labeling conventions, some listing total content and others listing each component, so a “10mg blend” from one supplier and a “10mg blend” from another may contain different amounts. Third, at least one listing sold as a blend is two separate vials. Protide Health’s 10mg/10mg vial is lowest per milligram at $6.25, followed by Simple Peptide at $6.50, while Sports Technology Labs is highest at $14.50.
What is the difference between a 5/5mg and a 10/10mg blend?
A 5mg/5mg vial contains 5mg of CJC-1295 and 5mg of Ipamorelin, for 10mg of total peptide. A 10mg/10mg vial contains 10mg of each, for 20mg of total peptide, twice the material. The larger presentation is generally cheaper per milligram: at Protide Health the 5mg/5mg vial is $7.50 per milligram and the 10mg/10mg vial is $6.25.
Is the CJC-1295/Ipamorelin blend legal to buy in the United States?
CJC-1295 and Ipamorelin are sold in the United States as research chemicals for laboratory use only. Neither is approved by the FDA for human or animal use, and neither is a federally controlled substance. Suppliers in this category sell them exclusively for in vitro and laboratory research, and reputable ones state that restriction on every product page and require purchasers to confirm they are qualified research personnel. State and institutional rules vary, and research use is subject to applicable local, state, and federal regulations.
Is CJC-1295 the same as Ipamorelin?
No. They are two chemically distinct synthetic peptides that happen to be commonly supplied together. CJC-1295 without DAC is a 29-amino-acid analogue of GHRH with the formula C152H252N44O42 and a molecular weight of 3,367.9 g/mol. Ipamorelin is a five-amino-acid pentapeptide with the formula C38H49N9O5 and a molecular weight of 711.86 g/mol. They are catalogued in PubChem as separate compounds under separate CAS numbers.
What should a CJC-1295/Ipamorelin certificate of analysis show?
At minimum: a specific lot number, a distinct certificate number, a recent reporting date, an HPLC purity figure, and mass spectrometry identity confirmation. The certificate should also report net peptide content or measured quantity separately for CJC-1295 and for Ipamorelin. Five of the ten suppliers here do this. The strongest documents go further, confirming identity by mass against an expected value for each compound individually and reporting results per vial rather than from a single composite sample. Endotoxin results under USP <85>, microbial screening, and heavy metal panels are additional signals that few suppliers publish. A good example is Protide Health’s CJC-1295 (No DAC)/Ipamorelin 5/5mg COA which contains all the above.
Conclusion
Deciding where to buy CJC-1295/Ipamorelin in 2026 is less about the advertised purity figures, which sit within a fraction of a percent of each other across every supplier in this category, and more about which supplier will show a certificate tied to the specific lot in the vial and name the laboratory that produced it. On that standard Protide Health ranks first: a named laboratory printed on the certificate and signed by its principal chemist, a seven-part panel running LC-MS identity, HPLC-UV purity, net peptide content, USP <85> endotoxin, PCR microbial screening, ICP-MS elemental impurities and a fentanyl screen, two vials assayed per lot with net content split by compound, and the lowest cost per milligram of the ten suppliers compared here. No other certificate reviewed for this guide covers more than four of those seven tests.
