Epigen vs FGL
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 →FGL
FGL (FG Loop) is a synthetic peptide that mimics the neural cell adhesion molecule (NCAM) FG loop region. It promotes neuroplasticity and has shown cognitive-enhancing effects in research.
Full details →Side-by-Side Comparison
| Aspect | Epigen | FGL |
|---|---|---|
| Mechanism | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. | Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival. |
| Typical Dosage | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. | Research protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established. |
| Administration | Primarily topical application for skincare. Research may use other routes for systemic effects. | Subcutaneous injection or intranasal administration. Research compound with limited human dosing data. |
| Side Effects | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. | Limited human data available. Animal studies show good tolerability. |
