Epigen vs Melanotan II

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Epigen

Epigen is a member of the epidermal growth factor (EGF) family. It plays roles in skin regeneration and has been studied for wound healing and anti-aging applications.

Side-by-Side Comparison

Aspect	Epigen	Melanotan II
Dose Range	100 mcg–500 mcg	250 mcg–1 mg
Frequency	1x daily	1x daily
Cycle Length	4–8 weeks	1–2 weeks
Route	subcutaneous	subcutaneous
Mechanism	Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes.	Non-selective melanocortin receptor agonist affecting MC1R (tanning), MC3R and MC4R (sexual function and appetite). This broader activity explains its multiple effects beyond tanning.
Typical Dosage	Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary.	Typical 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.
Administration	Primarily topical application for skincare. Research may use other routes for systemic effects.	Subcutaneous injection. Usually combined with UV exposure for tanning effects. Nasal spray formulations exist but have lower bioavailability.
Side Effects	Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation.	Nausea (common initially), facial flushing, spontaneous erections, increased libido, appetite suppression, and mole darkening.
