NA-Semax Amidate vs Epigen
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
NA-Semax Amidate
NA-Semax Amidate (N-Acetyl Semax Amidate) is a modified version of Semax with enhanced stability and potency. Also known as NASA, it provides stronger and longer-lasting nootropic effects than standard Semax.

| Aspect | NA-Semax Amidate | Epigen |
|---|---|---|
| Mechanism | Maintains Semax's core actions on BDNF, NGF, and monoamine systems with improved pharmacokinetics. The modifications enhance CNS penetration and extend duration of action. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
