Side-by-Side Comparison

Aspect	Epigen	Thymosin Alpha-1
Dose Range	100 mcg–500 mcg	1.6 mg–3.2 mg
Frequency	1x daily	Less than daily
Cycle Length	4–8 weeks	4–12 weeks
Route	subcutaneous	subcutaneous
Mechanism	Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes.	Enhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes.
Typical Dosage	Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary.	Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary.
Administration	Primarily topical application for skincare. Research may use other routes for systemic effects.	Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols.
Side Effects	Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation.	Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue.
