What is Melanotan 2?

Melanotan 2 is a seven-amino-acid cyclic peptide originally developed at the University of Arizona during sunless-tanning research. It is structurally related to, but pharmacologically broader than, the more receptor-selective compound Melanotan 1, also known as afamelanotide.

This listing is Melanotan 2 from Vital Edge Science (Australia & New Zealand), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

Unlike Melanotan 1, which acts mainly at MC1R, Melanotan 2 is a non-selective agonist across MC1R, MC3R, MC4R and MC5R. MC1R activation on melanocytes drives melanin production, while central MC3R/MC4R activity in the hypothalamus has been linked in study models to effects on appetite and sexual-arousal pathways, part of why MT-2 shows a broader activity profile than the more selective Melanotan 1.

Research status

Melanotan 2 is studied in research on skin pigmentation, melanocortin receptor pharmacology, appetite regulation and sexual-arousal signaling. Its non-selective receptor activity subsequently informed the development of bremelanotide (PT-141), a related, more targeted melanocortin agonist now FDA-approved for a specific indication, though Melanotan 2 itself remains an unapproved research compound.

Questions

How does Melanotan 2 differ from Melanotan 1?

Melanotan 1 is a more receptor-selective analogue acting largely at MC1R, while Melanotan 2 is non-selective across MC1R, MC3R, MC4R and MC5R, which is why the two peptides are studied for a broader, more overlapping range of effects in the case of MT-2.

Is Melanotan 2 related to any approved medicine?

It is a structural relative of bremelanotide (PT-141), an FDA-approved melanocortin-receptor agonist, but Melanotan 2 itself is a distinct, non-selective compound that has not been approved as a drug.
