- GHK-Cu (Copper Peptide)
- Tyrosinase activation via copper ion delivery
- +28% tyrosinase activity, +34% melanin synthesis (72h)
- ~30 minutes plasma; tissue retention 4–6 hours
- 1–10 μM in vitro; 1–3 mg/kg in vivo
- Best alternative for direct melanogenesis support without MC1R activation. Works through enzymatic pathway
- BPC-157
- Angiogenesis and growth factor upregulation
- +55% VEGF, +42% wound closure rate
- ~4 hours (estimated, unstable in plasma)
- 10 μg/kg daily (animal models)
- Ideal for tissue repair research where improved vascular support enhances melanocyte function indirectly
- Epithalon
- Telomerase activation and pineal regulation
- +33 base pairs telomere length, +19% skin elasticity
- ~30 minutes plasma; cellular effects persist weeks
- 5–10 mg per cycle (human trials)
- Best for longevity and circadian research. Pigmentation benefits are secondary to systemic cellular health
- Thymosin (Thymalin)
- Immune modulation and cytokine regulation
- −40% IL-6, −35% TNF-alpha, +22% regulatory T-cells
- ~2 hours plasma; immune effects last 7–14 days
- 10–100 μg per dose (clinical trials)
- Best for inflammatory skin conditions where immune dysregulation suppresses normal melanocyte activity
- Melanotan-1 (Reference)
- MC1R receptor agonist
- Direct melanin synthesis via cAMP pathway
- ~33 minutes plasma; effects persist 48–72h per dose
- 0.1–1.0 mg per dose (human trials)
- Direct melanocortin pathway. Fastest visible pigmentation but requires receptor activation
