Melanotan II

Melanotan II is a man-made copy of a natural body chemical that controls skin color. It is not a real medicine. It is usually sold as a powder that people mix and inject under the skin. People who want a tan without much sun often look for it online.

Its main effect is that it tells skin cells to make more of the dark pigment that gives skin a tan color. It may also lower appetite and cause erections in men. The tanning effect is the reason most people try it. It became popular because a tan can appear with little time in the sun.

There is no strong proof it is safe. No big health group has approved it, and doctors do not know if the products sold online are clean or even real. It can cause nausea, flushing, and unwanted dark spots on the skin. Health agencies warn people not to buy or inject it because it is made in unknown places with unknown quality.
