Skin Pigmentation
Sexual & Reproductive Health

Overview

Melanotan II stimulates melanin production by activating melanocortin receptors in the skin. It allows you to develop a tan with minimal UV exposure, providing some protection against sunburn. MT-II also crosses the blood-brain barrier, which can affect appetite and libido as secondary effects.

Key Benefits & Mechanisms

Melanin Production

Activates MC1R receptors to boost natural melanin in skin

Sunburn Protection

Increased melanin helps absorb UV and reduce burning

Libido Enhancement

Activates MC4R in the brain, often increasing sex drive

Appetite Effects

May reduce appetite through central nervous system activity
