Epigen vs SS-31 (Elamipretide)

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	SS-31 (Elamipretide)
Dose Range	100 mcg–500 mcg	20 mg–40 mg
Frequency	1x daily	1x daily
Cycle Length	4–8 weeks	4–12 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.	Concentrates in the inner mitochondrial membrane where it binds to cardiolipin, stabilizing electron transport chain function, reducing reactive oxygen species, and improving ATP production efficiency.
Typical Dosage	Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary.	Clinical trials have used IV infusions of 0.25mg/kg for acute conditions. Subcutaneous dosing protocols for research use typically range from 1-5mg daily.
Administration	Primarily topical application for skincare. Research may use other routes for systemic effects.	Can be administered IV or subcutaneously. Most clinical research has used IV administration for cardiac conditions.
Side Effects	Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation.	Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache.
