Skin / sexual health
Melanocortin (MC1R / MC4R) receptor activation produces two main effects: skin pigmentation (melanin synthesis, UV protection, cosmetic) and centrally-mediated libido / sexual response. The peptide also supports collagen I/III and elastin synthesis, improving skin elasticity and texture, youth markers measurably rise. Acute effect (libido, energy) often within 30–60 min; lasting effects (tone, pigmentation) build over 1–3 weeks. Routine mole checks recommended.
