Understand this compound
What is Melanotan I?
FDA-approved moleculea.k.a. Afamelanotide, ScenesseA lab-made version of the hormone that tells your skin to make pigment. The regulated version (Scenesse) is approved for a rare light-sensitivity disease — grey-market tanning vials are not that product.
Good to know: FDA approval covers only the specific regulated formulation and indication (erythropoietic protoporphyria); unregulated 'Melanotan-1' sold for cosmetic tanning is not the same controlled product and lacks that oversight.
How does Melanotan I work?
The science
A synthetic analog of alpha-MSH selective for the MC1 receptor, stimulating melanocytes to increase eumelanin production and skin pigmentation.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Melanotan I researched for?
Studied for photoprotection in light-sensitive conditions and UV-independent skin pigmentation.
- Tanning & libidoStudied in melanocortin research — skin pigmentation and related pathways.
How far has the research gone?
FDA-approved (for erythropoietic protoporphyria) — approved as Scenesse in 2019 following Phase 3 trials.
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.

Compare by real cost
Every Melanotan I listing, cheapest per mg first
Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 13 are here: the last 4 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

Open the full Melanotan I market
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. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.
Independent testing
Melanotan I — 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.

What the research says
Scientific evidence & regulatory status
What the published literature actually shows about Melanotan I — separate from any vendor’s marketing. Each finding links to its paper. This is education, not medical or dosing advice.
Regulatory status
An approved drug exists — this is not it
Afamelanotide is FDA-approved as SCENESSE (October 2019) and EMA-authorized since December 2014 under exceptional circumstances, but only as a controlled-release implant placed under the skin by a healthcare professional, to reduce phototoxicity in adults with erythropoietic protoporphyria. The injectable 'Melanotan I' sold online is not that product.
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.
General information, not legal or medical advice. VialGrade sells nothing and encourages no human use.
