Scientific Background

Melanotan II is a synthetic cyclic analog of alpha-melanocyte-stimulating hormone (α-MSH), engineered to strongly activate melanocortin receptors (MC1R, MC3R, MC4R) and promote melanin synthesis. It binds MC1R to increase eumelanin production, resulting in rapid skin darkening and enhanced UV tolerance. Unlike natural sun exposure, it delivers consistent, even pigmentation with less UV risk. The pre-filled 10 mg pen enables straightforward daily subcutaneous administration.

Intended Research Use

MC1R-mediated melanin synthesis and pigmentation research
Photoprotection and UV resistance studies
MC4R signaling and appetite suppression research
Skin darkening efficiency and tanning protocol studies
Melanocortin receptor pharmacology investigations
