NA-Selank Amidate vs Palmitoyl Tetrapeptide-7
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.
Full details →Palmitoyl Tetrapeptide-7
Palmitoyl Tetrapeptide-7 is an anti-inflammatory peptide that reduces IL-6 secretion. Combined with Palmitoyl Tripeptide-1, it forms Matrixyl 3000, addressing both collagen production and inflammation.

| Aspect | NA-Selank Amidate | Palmitoyl Tetrapeptide-7 |
|---|---|---|
| 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. | Suppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides. |
| Typical Dosage | Intranasal: 100-400mcg 1-3 times daily. Lower doses needed compared to standard Selank due to enhanced bioavailability. | Topical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex. |
| Administration | Primarily intranasal administration. Can be used sublingually. More stable in solution than standard Selank. | Topical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin. |
| Side Effects | Generally well-tolerated. Possible mild fatigue or nasal irritation. Less frequent dosing needed than standard Selank. | Excellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin. |
