Where to buy Sermorelin (also sold as Sermorelin acetate, GHRH (1-29)): the 5 vendors below are the ones we have a dated product-page price for, ranked on documentation first and price second. Nothing here is typed from memory — every number links to a date.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.
Reference size 10mg — the size most of these vendors sell. Other sizes we have on record are listed per vendor.

Sermorelin is one of the older growth-hormone-releasing peptides on the market and nearly every research vendor lists it, usually beside CJC-1295, tesamorelin and ipamorelin. The three GHRH-type compounds are chemically distinct — sermorelin is the first 29 residues of native GHRH, CJC-1295 is a modified version of the same fragment, tesamorelin adds a further N-terminal group — and catalogs do not always keep the names straight.
Most vendors sell it as sermorelin acetate, which is the same peptide with an acetate counter-ion from purification; a certificate reports purity on the peptide, not the salt. Some vendors also sell sermorelin blended with a GHRP, and a blend price cannot be compared with a single-compound vial.
Because it is widely stocked and inexpensive to synthesise, sermorelin is a compound where the spread between vendors is driven almost entirely by documentation rather than by the peptide itself. The table above applies the same rubric to each seller and shows a dated product-page price beside it.
What we can verify
Publishes per-lot COAs naming the testing laboratory — SteriGenix and Freedom Diagnostics — with lot numbers, test dates, measured net peptide content and direct verify-at-lab links. HPLC and mass spectrometry testing, US-based fulfilment from Scottsdale, Arizona, same-day dispatch on weekday orders before 2PM EST, and a 60-day money-back guarantee.
Net content: Measured net peptide published per lot (e.g. BPC-157 lot PL-BPC-05: 11.16mg vs 10mg label)
Where it falls short
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
What we can verify
Names Janoshik Analytical and Vanguard Laboratory; certificates resolve on the lab's own domain (verify.janoshik.com). Product pages list dated batch codes for previous certificates, no account required. Legal entity, Tampa, FL address, EIN and sales-tax number published: Plainview Commerce LLC. Full basket with sized pricing, stable across reads.
Net content: Vanguard Laboratory PDF for lot PG-5101 (TB-500 5mg) reports 4.92mg measured vs 5mg, 99.30% purity — read 6 Sep 2026
Where it falls short
Small review base (65 on Trustpilot, 26 Sep 2026). Measured net content could not be read from the certificate images. The legal entity name appears on the refund policy but not the About page. GLP products sold under house codes PG-1SG / PG-2TZ / PG-3RT.
What we can verify
Names North American Diagnostics, and the lab's own portal returns the record for test ID NAD-0037963 (BPC-157, lot PSP-09112026BP, 99.97%, 4.88mg on a 5mg label) — looked up 3 Oct 2026. 59 certificates downloadable without an account, sized pricing across the widest GLP range we cover, card checkout (Visa/Mastercard/Amex/Discover, Afterpay, Klarna). The September '5-star from thousands' blog claim is gone, so the clean-record point is now awarded.
Net content: Measured mass vs label published (4.88mg on a 5mg label on NAD-0037963, 97.6%; 5.03mg on PSP-0028020 in Sep)
Where it falls short
Home and about pages claim 'cGMP-certified facilities' and 'accredited laboratories' while the vendor's own legit post says cGMP certificates do not exist, and no accrediting body is named. The ProSupply Services LLC name we read in September is no longer printed anywhere; 'New Jersey-based' only, no address, email-only support. Trustpilot 4.3 is still the low end of the partner set.
Purgo Labs sits at #1 of 5 on this page: 10/10 on the rubric, 10mg at $47.99 read 23 Sept 2026. Code HEALTH gives 20% off every order. We earn a commission; it did not decide the order above.

A ranking tells you which vendors have good practices; it cannot tell you about the specific vial you receive. When your order arrives, compare the batch number on the label to the certificate. If they do not match, or there is no batch number, the documentation does not cover what you were sent, regardless of who you bought from. How to read a peptide COA.
As of 23 Sept 2026, 5 of the 78 vendors on our scoreboard list Sermorelin with a price we have read on the product page: Purgo Labs, Peptide Giants, PS Peptides, Modern Aminos, Elite Edge Biotech. Every one of them is scored on the same 10-point rubric; the table above shows the score, the dated price and what you can verify before ordering.
At the 10mg size, the lowest price we have on record is Peptide Giants at $45.00 (read 23 Sept 2026) — list price; acetate; sold as 'Sermorelin Acetate'. It scores 10/10 on documentation. Price is the second sort key on this page, not the first, because an underdosed vial at a low price is the most expensive outcome.
Purgo Labs and Peptide Giants share the top score at 10/10: named laboratory, certificates that resolve on the laboratory's own site, measured milligrams against the label, and a published legal identity. The per-criterion evidence, with dates, is on each vendor's review page.
Sermorelin is sold by these vendors as a research chemical for laboratory use, not for human consumption; none of it is FDA-approved in this form. Legality of purchase varies by jurisdiction and the compound, and it is your responsibility to know your local rules. Our pages assess documentation and pricing; they are not legal or medical advice.
Rubric score first. Among equal scores, the lower verified price per milligram at 10mg. Then the larger independent review base. Affiliate partnership is not an input: 5 of the 5 vendors here are partners and they sit wherever the evidence puts them.
No. Acetate is the counter-ion left from purification, and it is how almost all synthetic peptides are supplied. Vendors list the product under either name. The certificate reports purity of the peptide, and net content is stated for the peptide, not the salt, when the vendor bothers to state it at all.
Both are fragments of growth-hormone-releasing hormone. Sermorelin is the unmodified 1-29 fragment; CJC-1295 without DAC (also called Mod GRF 1-29) carries four amino-acid substitutions that slow its breakdown, and the DAC version adds a further group that extends its half-life to days. They are priced differently and are not interchangeable in a research design.
