Melanotan II Acetate – Overview

Melanotan II (MT-II) is a synthetic cyclic peptide derived from the naturally occurring hormone α-melanocyte-stimulating hormone (α-MSH). It was originally developed for photoprotection (reducing UV-induced skin damage) but later gained attention for its broader effects on pigmentation, sexual function, appetite, and energy balance.

The acetate refers to the salt form used to improve stability and handling, not the biological activity itself.

Mechanism of Action

Melanotan II works by activating melanocortin receptors (MCRs), particularly:

  • MC1R → stimulates melanin production in melanocytes

  • MC3R & MC4R → involved in appetite regulation, energy metabolism, and sexual behavior

Unlike Melanotan I, MT-II is non-selective, which explains its wider range of physiological effects.

Primary Biological Effects

Skin Pigmentation

  • Increases eumelanin production, leading to darker skin pigmentation

  • Enhances tanning independently of UV exposure

  • May offer some degree of UV protection due to higher melanin levels

Sexual Function

  • Strongly associated with increased libido and sexual arousal

  • Effects are mediated mainly through MC4R activation

  • This property led to the development of bremelanotide (PT-141), a derivative used clinically

Appetite & Weight Regulation

  • Can cause appetite suppression

  • May contribute to fat loss via central melanocortin pathways
