Side-by-Side Comparison

AspectMelanotan IIEpigen
MechanismNon-selective melanocortin receptor agonist affecting MC1R (tanning), MC3R and MC4R (sexual function and appetite). This broader activity explains its multiple effects beyond tanning.Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes.
Typical DosageTypical protocols: 0.25-0.5mg daily during loading phase for 1-2 weeks, then 0.5-1mg before UV exposure for maintenance. Start low to assess tolerance.Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary.
AdministrationSubcutaneous injection. Usually combined with UV exposure for tanning effects. Nasal spray formulations exist but have lower bioavailability.Primarily topical application for skincare. Research may use other routes for systemic effects.
Side EffectsNausea (common initially), facial flushing, spontaneous erections, increased libido, appetite suppression, and mole darkening.Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation.
