Melanotan II (MT2) is a peptide used to stimulate the production of melanin. It’s used as a skin cancer treatment drug. It’s been widely used in bodybuilding circles for years primarily as a means of achieving darker skin tone with minimal sun exposure. It also has a heightened effect on libido in both males and females and seems to accomplish this through a neurological pathway that hasn’t been researched enough yet. It’s also known to improve insulin sensitivity.

I’ve used it regularly for almost a decade now and other than some mild post-injection nausea, haven’t had any adverse side effects.

Might be a good tool if what Jack is talking about has real merit.
