NA-Selank Amidate vs Epigen
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
NA-Selank Amidate
NA-Selank Amidate (N-Acetyl Selank Amidate) is an enhanced version of Selank with improved stability and blood-brain barrier penetration. The modifications increase bioavailability and duration of cognitive and anxiolytic effects.

| Aspect | NA-Selank Amidate | Epigen |
|---|---|---|
| Mechanism | Same core mechanism as Selank - modulates BDNF, serotonin, and norepinephrine systems. The N-acetyl group improves membrane permeability while the amidate modification increases enzymatic stability. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Intranasal: 100-400mcg 1-3 times daily. Lower doses needed compared to standard Selank due to enhanced bioavailability. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Primarily intranasal administration. Can be used sublingually. More stable in solution than standard Selank. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | Generally well-tolerated. Possible mild fatigue or nasal irritation. Less frequent dosing needed than standard Selank. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
