Melanotan II is a cyclic analogue of alpha-melanocyte-stimulating hormone and one of the most searched compounds on the research market. Vendors label it MT-2, MT2, Melanotan 2 or Melanotan II; all refer to the same peptide. The one it must not be confused with is Melanotan I (afamelanotide), a linear analogue that some catalogs list as MT-1 at a different price.
Because it is popular and cheap to synthesise, it is also one of the compounds most often sold by vendors with no documentation at all. The catalogs we read for this page ranged from vendors with laboratory-verifiable certificates to vendors that publish a purity claim and nothing else.
Vial sizes are unusually consistent across vendors for this compound, so the price comparison is cleaner than for most; the ordering is still by rubric score first, because price is not what goes wrong with an undocumented vial.
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 Freedom Diagnostics (Nashville) as its per-batch testing lab — the same laboratory Purgo Labs uses. 43-product catalog with public sized pricing. 4.9 across 561 Trustpilot reviews on a claimed, active profile (read 19 Sep 2026). Free same-day shipping (order by 12pm CT), 30-day money-back, published street address in Gallatin, TN.
Net content: Certificate reports 1.19mg measured vs 1mg label, 99.76% purity
Where it falls short
Scored 10/10 on 19 Sep 2026, up from 8/10, and the timing is disclosed rather than buried: Rivn became an affiliate partner the same day, and that is what prompted the re-read. The two points it had been missing came from a single on-site '4.9 (1,247 reviews)' widget that contradicted the real Trustpilot record; that widget is gone, no in-house review count replaced it, and a searchable 47-certificate library now sits where seven loose images were in August. Full evidence and the exact pages checked are in the score history. Still vendor-stated and unverified: 'ISO 9001 certified facilities', 'Certified GMP', and the lab's ISO/IEC 17025 accreditation — claims we note but do not score.
What we can verify
4.7 across 90 Trustpilot reviews. Certificate images with batch codes viewable without an account. Sized pricing (BPC-157 10mg $30.00).
Net content: Certificate reports Net Peptide Content 10.50mg vs 10mg label, 98.509% purity (lot TPBP32826)
Where it falls short
The lab (Freedom Diagnostics) appears only on the certificate image, never in page text; the certificate carries a lab search code (Trus2604010178) and reports 10.50mg vs 10mg label. No legal entity and no address on About, Contact or Terms — 'Location: United States' only. Weight-loss compounds sold as 'TP-TZ' and 'TP-RT' with the identity never stated; those prices are excluded from our index. Domain under a year old.

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, 10 of the 78 vendors on our scoreboard list Melanotan II with a price we have read on the product page: Purgo Labs, Rivn Peptides, TrustedPeps, PS Peptides, Everest Peptides, Puratek Peptides, Modern Aminos, Elite Edge Biotech, Arizen BioLabs, 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 TrustedPeps at $20.00 (read 23 Sept 2026) — sale; list $30.00 struck; sold as 'MT2 10MG'. It scores 9/10 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 leads 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.
Melanotan II 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: 9 of the 10 vendors here are partners and they sit wherever the evidence puts them.
Melanotan I (afamelanotide) is a linear peptide and is an approved prescription implant in some countries for a specific photodermatosis. Melanotan II is a shorter cyclic analogue with broader receptor activity. Research vendors sell both, sometimes as MT-1 and MT-2 on adjacent listings; the certificate's mass-spectrometry identity is what confirms which one is in the vial.
The peptide is inexpensive to make, so the difference between vendors is mostly what they spend on testing, identity and business infrastructure. A vendor at the low end of the price range with no verifiable certificate is asking you to trust the label; the rubric score on this page tells you which vendors have given you something to check.
