Where to buy PT-141 (also sold as Bremelanotide): the 8 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.

PT-141 is the research-market name for bremelanotide, a melanocortin-receptor agonist derived from Melanotan II. It is sold in two forms that are not comparable on price: a lyophilised vial for reconstitution, and a pre-made nasal or 'atomised' solution sold by volume. The table on this page covers the lyophilised vial only; solution listings are excluded because a millilitre price says nothing about peptide content.
Because PT-141 and Melanotan II are closely related and often sold side by side, the certificate matters for identity as well as purity: the two differ by a small change in structure, and a mass-spectrometry check on the certificate is what tells them apart.
It is a widely stocked compound, which means the price spread between vendors is mostly a documentation spread. The rubric score comes first in the ordering below for that reason.
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 8 on this page: 10/10 on the rubric, 10mg at $29.99 read 2 Oct 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 2 Oct 2026, 8 of the 77 vendors on our scoreboard list PT-141 with a price we have read on the product page: Purgo Labs, Peptide Giants, PS Peptides, Everest Peptides, Puratek Peptides, Modern Aminos, Elite Edge Biotech, Licensed Peptides. 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 Elite Edge Biotech at $28.00 (read 23 Sept 2026) — sale; list $54.99 struck; PT-141 10mg; sold as 'PT-141 10mg'. It scores 6/10 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.
PT-141 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: 7 of the 8 vendors here are partners and they sit wherever the evidence puts them.
Yes. Bremelanotide is the non-proprietary name; PT-141 was the development code and is what research vendors use. A prescription product containing bremelanotide exists in some countries; what research vendors sell is not that product and is not approved for human use.
No. A lyophilised vial states a milligram amount of peptide; a spray or atomised solution is priced by volume with a stated concentration that the certificate may or may not verify. This page ranks vials. If a vendor only sells the solution, it does not appear here.
