| Aspect | AHK-Cu | Epigen |
|---|---|---|
| Dose Range | 1 mg–10 mg | 100 mcg–500 mcg |
| Frequency | 2x daily | 1x daily |
| Cycle Length | 4–8 weeks | 4–8 weeks |
| Route | topical | subcutaneous |
| Mechanism | The copper-binding tripeptide stimulates collagen synthesis and may promote hair follicle enlargement. Works similarly to GHK-Cu but may have distinct receptor interactions. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Topical application to skin or scalp. Can be used with microneedling for enhanced penetration. May cause temporary blue-green tint at high concentrations. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | Generally well-tolerated. May cause skin irritation in sensitive individuals. Temporary discoloration possible. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
