It is used to promote tanning. It works by stimulating alpha-melanocyte receptors, which promote melanin formation in response to sun exposure. By applying Melanotan-2 to the recent “memory” of skin cells, a person tans as if they were genetically darker. The effect of Melanotan-2 is long-lasting. Even the effect of one cycle takes a year to wear off. Maintenance cycles achieve an indefinitely long effect. As a general rule, maintenance typically requires about 2 to 3 times a year. It has pro-sexual effects, significantly improving libido.

In addition to the tanning and libido-boosting effects, Melanotan II has been observed to reduce adipose tissue and suppress appetite. Melanotan II triggers the release of more leptin from fat cells, a hormone responsible for lipolysis. It also reduces insulin resistance and increases fatty acid oxidation. But the main mechanism by which it reduces the adipose layer is the lack of appetite, thus reducing caloric intake.
