Melanotan II (MT2) is a synthetic peptide analog of the naturally occurring hormone α-melanocyte-stimulating hormone (α-MSH). It is designed to interact with melanocortin receptors, particularly those involved in pigmentation and certain central nervous system functions.

Research suggests MT2 may:

• Stimulate melanin production, potentially increasing skin pigmentation

• Influence appetite and energy balance via melanocortin pathways

• Affect libido and sexual function through central receptor activity

• Provide photoprotective effects by increasing melanin levels

MT2 primarily acts by binding to melanocortin receptors (e.g., MC1R, MC3R, MC4R), which are involved in pigmentation, metabolism, and neurological signaling.

Melanotan II (MT2) is intended for research and laboratory use only.
