Epigen vs Retatrutide
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.
Full details →Retatrutide
Retatrutide is an investigational triple agonist targeting GIP, GLP-1, and glucagon receptors. Phase 2 trials showed unprecedented weight loss of up to 24% at 48 weeks, making it potentially the most effective obesity treatment studied.

| Aspect | Epigen | Retatrutide |
|---|---|---|
| Mechanism | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. | Triple receptor activation provides complementary metabolic effects: GLP-1 and GIP reduce appetite and improve insulin sensitivity, while glucagon receptor activation increases energy expenditure and promotes hepatic fat oxidation. |
| Typical Dosage | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. | Clinical trials used doses from 1mg to 12mg weekly. Optimal dosing still being determined in ongoing Phase 3 trials. |
| Administration | Primarily topical application for skincare. Research may use other routes for systemic effects. | Subcutaneous injection once weekly. Currently only available through clinical trials - not yet FDA approved. |
| Side Effects | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. | Similar GI effects to other incretin-based therapies: nausea, diarrhea, vomiting, constipation. Dose-dependent severity. |
