Melanotan is a lab-made chemical. It is similar to a hormone found in the body. It was originally made as a drug to help treat certain skin conditions. It is also sold over the internet as a supplement.
Melanotan is commonly used for skin tanning. It is also used to produce erections in men with erectile dysfunction (ED), for rosacea, for fibromyalgia, and other conditions, but there is no good scientific evidence to support most of these uses. There is also concern that melanotan might not be safe when used as a shot under the skin.
Be careful not to confuse melanotan with melatonin.
How does it work ?
Melanotan is similar to a substance in our bodies, called “melanocyte-stimulating hormone.” This hormone increases the production of skin-darkening pigments. Melanotan might also work in the brain to stimulate erections of the penis.
