Melanotan refers to a synthetic peptide that is designed to stimulate the production of melanin in the body. Melanin is a pigment responsible for the color of the skin, hair, and eyes. Melanotan comes in two variations: Melanotan I and Melanotan II.
Melanotan I and II are primarily used for tanning purposes. People use them to achieve a darker skin tone without having to spend extended periods in the sun. This is of interest to those who desire a tan but are concerned about the potential risks of excessive sun exposure, such as skin damage and increased risk of skin cancer.
Melanotan II, in particular, has gained attention for its ability to not only induce tanning but also potentially increase libido and reduce appetite. Is thought to interact with certain receptors in the brain that play a role in sexual behavior and arousal.
