Understand this compound

What is Melanotan II?

Limited human dataa.k.a. Melanotan II, MT-2

A melanocortin peptide studied in tanning and libido research — the most-discussed 'tanning peptide'.

Tanning & libido

Good to know: Multiple published case reports link it to new or changing moles, dysplastic nevi, and melanoma, as well as priapism, rhabdomyolysis, and renal infarction, with uncontrolled product purity and dosing.

How does Melanotan II work?

A non-selective cyclic analog of alpha-MSH that activates MC1, MC3, and MC4 receptors, increasing melanin production while also affecting appetite and sexual arousal pathways via MC4R.

Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.

What is Melanotan II researched for?

Used off-label/grey-market for skin tanning and, informally, libido or appetite effects, though never developed as an approved drug for these uses.

  • Tanning & libidoStudied in melanocortin research — skin pigmentation and related pathways.
How far has the research gone?

Limited human data — no completed efficacy trials or regulatory approval exist anywhere; it is used almost exclusively as an unregulated grey-market product.

Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.

What should I check before buying?
  • Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
  • Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
  • Vendor reputation. See how the vendor is talked about in the community before trusting a new name.

Research context only — VialGrade never gives dosing, medical, or human-use guidance.

US legal status

Research-use-only — not FDA-approved

Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg.

Commonly researched together

Often stacked with Melanotan II

Compounds the research community frequently discusses alongside Melanotan II. Not a protocol or a recommendation — a starting point for what to read about next.

Independent testing

Melanotan II — independent lab tests

Real, publicly verifiable third-party tests. Purity is read from the certificate itself. A test reflects one lab’s result for one submitted batch — not a guarantee that every vial matches.

How does this data get here?

Every record below is a real certificate of analysis, gathered two ways: from the public verification feeds that independent labs (like Janoshik) publish, and from the certificates vendors post on their own product pages. We open each certificate document and read the measured purity, content, batch, and date directly off it — a scraper can’t read a number printed inside an image, so this is done by machine vision, then recorded here with a link back to the original.

Nothing here is typed in by a vendor or invented by us. Where a certificate is missing, we say so rather than filling the gap.

We re-check the lab feed, too. A “still listed” tag means the certificate is currently public in Janoshik’s database — we re-verify against the live feed and stamp the date. If a cert is later pulled, the tag flips. It’s a freshness check on the same source, not a second independent opinion.

What a certificate does & doesn’t prove

Three different questions. Purity (“how clean?”), identity (“is it the right molecule?”, a mass-spec test), and content (“did I get the labeled mg?”) are separate. A vial can be 99% pure and still be the wrong peptide, or the right peptide underdosed. We flag the measured dose against the label above; underdosing is the most common real fraud.

Who submitted the sample matters. Most of these are vendor-submitted — the seller chose which vial to send, so one good certificate doesn’t prove every batch is the same. The gold standard is a blind test, where a buyer sends a vial they bought as a normal customer. Same label doesn’t prove same product; same batch number doesn’t prove same batch.
