What is Melanotan 1?

Melanotan 1 is a linear 13-amino-acid peptide engineered from the native alpha-MSH sequence for improved metabolic stability and receptor potency. Under the name afamelanotide, the same molecule is also the active ingredient of an approved implant medicine used for a rare photosensitivity condition, giving this compound an unusually well-documented clinical background for a research peptide.

How it is understood to work

Melanotan 1 acts as an agonist at the melanocortin-1 receptor (MC1R) on melanocytes, activating cAMP signaling that upregulates tyrosinase and downstream melanogenesis enzymes. This shifts pigment production toward eumelanin, the darker, more photoprotective melanin form, in study models.

Research status

Research on Melanotan 1 spans dermatology and photobiology, including studies of UV-independent pigmentation, protection against light-induced skin damage, and photosensitivity disorders. Because afamelanotide has completed clinical development for erythropoietic protoporphyria in several jurisdictions, a meaningful portion of the human data on this molecule comes from regulated clinical trials, distinguishing it from purely preclinical research peptides.

Questions

Is Melanotan 1 the same molecule as the approved drug afamelanotide?

Yes, afamelanotide is the generic name for the same 13-amino-acid alpha-MSH analogue; this research-grade material is supplied strictly for laboratory use and is not the approved pharmaceutical formulation.

How does Melanotan 1 differ from Melanotan 2?

Melanotan 1 is the linear, unmodified-ring analogue closely related to afamelanotide, while Melanotan 2 is a cyclic, shorter analogue with broader melanocortin receptor activity, including MC3R and MC4R, studied for additional effects beyond pigmentation.

How much Melanotan 1 is in this kit?

10 vials of 10 mg each, so 100 mg in total. The lab testing section above shows what the brand’s tested vial actually contained.
