Gonadorelin vs Epigen
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Gonadorelin
Gonadorelin is a synthetic form of gonadotropin-releasing hormone (GnRH). It stimulates the pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), supporting natural hormone production.

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 →Side-by-Side Comparison
| Aspect | Gonadorelin | Epigen |
|---|---|---|
| Mechanism | Binds to GnRH receptors in the pituitary gland, triggering pulsatile release of LH and FSH. This stimulates testicular or ovarian function and natural sex hormone production. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Men: 100-200mcg subcutaneously 2-3 times daily. Women (fertility): Per clinical protocol. HRT support: Often combined with other therapies. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Subcutaneous injection. Pulsatile administration mimics natural GnRH release patterns. Often used during or after testosterone therapy. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | Headache, flushing, injection site reactions. In women may cause ovarian hyperstimulation. Generally well-tolerated. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
