MT-II (Melanotan II)
MT-II (Melanotan II)
Melanotan II is a well-characterized synthetic analog of alpha-MSH — the body's own skin-darkening hormone. It's one of the most studied peptides in pigmentation research, with additional work covering appetite regulation and sexual arousal.
How MT-II (Melanotan II) Works
A deeper look for the curious
For readers who want the full mechanism — feel free to skim.
Melanotan II is a synthetic analog of alpha-MSH — the body's natural skin-darkening hormone. It activates melanocortin receptors that control pigmentation, appetite, and sexual arousal (the last of which is why PT-141, a related peptide, was developed).
