It is a synthetic amino acid protein discovered during clinical trials using the Melanotan 2 for sunless tanning, photo-protection results from melanotans. Participants were documented as having experienced aphrodisiac reactions, leading to the further development. The melanocortin system targets receptors associated with desire through the melanocyte stimulating hormone paths that cross the blood-brain-barrier. Potentially the powerful sex-drug results feeling an aphrodisiac experience amplifying arousal which reviews have shown the ability to increase libido effects of both men and women.

Applications
 Functions by activating the melanocortin 1 receptor and MC4R namely. It originally was tested for nasal spray delivery but was discontinued after concerns about side effects. As Melanotan II, may cause spontaneous arousal enhancing effect. Unlike other supplements,which results do not act on the vascular body, but directly increases desires through the nervous system.

It is the generic term for a peptide being studied for its possible use in helping to improve sexual dysfunction in both men (erectile dysfunction or impotence) and women (sexual arousal disorder). It has a similar structure to Melanotan-II and is a synthetic analogue of alpha-Melanocyte stimulating hormone (α-MSH). Alpha-MSH is an endogenous peptide that has potential influence over lipid metabolism, appetite, and sexual libido. It is a potential remedy for the treatment of sexual dysfunction and studies have shown that  does not act on the vascular system like former compounds, but allegedly works by activating melanocortin receptors in the brain, therefore helping increase ones sexual stimulation.
