Palmitoyl Tripeptide-1 vs NA-Selank Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Palmitoyl Tripeptide-1
Palmitoyl Tripeptide-1 (Pal-GHK) is a lipopeptide that stimulates collagen production. It's one of two peptides in the Matrixyl 3000 complex, working synergistically with Palmitoyl Tetrapeptide-7.
Full details →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 | Palmitoyl Tripeptide-1 | NA-Selank Amidate |
|---|---|---|
| Mechanism | Mimics the skin's own mechanism for producing collagen by acting as a messenger peptide that signals fibroblasts to produce more collagen and other extracellular matrix components. | 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. |
| Typical Dosage | Topical: Typically 2-4% in serums, often combined with Palmitoyl Tetrapeptide-7 as Matrixyl 3000. | Intranasal: 100-400mcg 1-3 times daily. Lower doses needed compared to standard Selank due to enhanced bioavailability. |
| Administration | Topical application 1-2 times daily. The palmitoyl group enhances skin penetration compared to non-lipidated versions. | Primarily intranasal administration. Can be used sublingually. More stable in solution than standard Selank. |
| Side Effects | Very well-tolerated. Suitable for most skin types including sensitive skin. | Generally well-tolerated. Possible mild fatigue or nasal irritation. Less frequent dosing needed than standard Selank. |
