Melanotan II (MT2) is a synthetic peptide that mimics the function of melanocyte-stimulating hormone to increase skin pigmentation
. While it is marketed online for tanning, weight loss, and enhanced libido, its use is unregulated and not approved by major health authorities like the FDA and the Therapeutic Goods Administration (TGA). The risks and potentially serious side effects associated with MT2 outweigh its purported benefits.
Purported benefits
The advertised benefits of MT2 stem from its action on several melanocortin receptors throughout the body.
Sunless tanning: MT2 stimulates melanocytes to increase the production of melanin, the pigment that darkens the skin. This can produce a tan with minimal to no UV exposure, offering an alternative for fair-skinned individuals or those with photosensitivity disorders.
Reduced UV exposure: By enhancing the body's natural tanning process, MT2 can create a protective layer of melanin to help absorb UV light, potentially reducing sun damage and the risk of some skin cancers.
Enhanced libido: MT2 activates receptors in the brain associated with sexual arousal, which can increase libido and sexual function in both men and women. During early clinical trials, it was noted to cause spontaneous erections in men.
Appetite suppression: By acting on melanocortin receptors that regulate appetite and metabolism, some users report reduced hunger and a spontaneous decrease in caloric intake.
Potential metabolic and immune support: In research settings, MT2 has shown potential to improve glucose and cholesterol metabolism, and some studies indicate it may have immune-modulating and neuroprotective effects. These effects are still under investigation
