Melanocortin research · Melanotan II

The peptide behind the sunless-tan studies.

Melanotan II is a cyclic α-MSH analogue supplied for laboratory research into melanin production, MC1R and MC4R receptor signalling, and the pathways linked to pigmentation, skin and sexual function. Every lot ships with an independent, lot-matched CoA.

What the research shows

One analogue, three melanocortin pathways.

Published research on Melanotan II spans dermatology, endocrinology and urology. We supply the compound, and the proof of what is in the vial.

MC1R
Pigmentation without UV

In the first human studies, melanin production and visible skin darkening were observed with minimal sunlight exposure.

Dorr et al., Life Sciences 1996
MC4R
Sexual-function pathway

Erectile responses were reported in placebo-controlled, double-blind studies of men with erectile dysfunction.

Wessells et al., J Urol 1998

Residues, cyclic and stabilised

A lactam bridge makes the seven-residue analogue far more resistant to breakdown than native α-MSH, which degrades within minutes.

Sequence: Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2

How it's studied

From receptor to pigment.

Melanotan II is a non-selective melanocortin agonist. Most of the published work follows it through three stops.

α-MSH01
Cyclic, stabilised analogue

The lactam ring resists enzymatic breakdown, so receptor exposure lasts long enough to measure.

MC1R02
Melanocytes and melanin

Binding on melanocytes shifts production toward eumelanin, the pigment measured in tanning and photoprotection studies.

MC4R03
Central signalling

Receptors in the hypothalamus are the ones tied to the arousal and appetite findings in the clinical literature.

We don't ask you to trust us. We ship the proof.

Every lot goes to Brown Biology Lab, an ISO-17025-accredited, A2LA-certified independent facility, before it leaves our floor. The CoA in your box is the one anyone can pull from the public library.

Six tests per lotHPLC purity, MALDI-TOF mass, endotoxin (LAL), bioburden, appearance and moisture, sequence verification.
Public, lot-matchedScan the lot on your vial and pull the same certificate from the CoA library. No private reports.
Replaced if it fails your assayRun your own test. If the lot doesn't match its certificate, send us the data and we replace it.
