Human Growth Hormone (HGH) vs Epigen
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Human Growth Hormone (HGH)
Human Growth Hormone (somatropin) is a 191-amino acid protein identical to naturally produced GH. FDA-approved for growth hormone deficiency, Turner syndrome, and other conditions. Widely used off-label for anti-aging and performance.

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.

| Aspect | Human Growth Hormone (HGH) | Epigen |
|---|---|---|
| Mechanism | Binds to GH receptors throughout the body, stimulating IGF-1 production in the liver. Promotes protein synthesis, fat metabolism, and cellular regeneration across multiple tissues. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Medical: 0.1-0.3mg/kg/week divided into daily doses. Anti-aging: 1-2 IU daily. Performance: 2-6 IU daily, sometimes higher. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Subcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | Joint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
