Melanotan I

Description

Melanotan I works by copying a natural hormone in the body called alpha-MSH. This hormone tells skin cells to make more melanin, which is the pigment that gives skin its color. When Melanotan I is in the body, it attaches to special receptors on skin cells. These receptors act like light switches—once Melanotan I connects, they turn on the signal to produce more melanin. As melanin levels go up, the skin starts to get darker, even without much sun exposure. This is how Melanotan I can help the body tan or protect the skin from sun damage.
