SNAP-8 vs NA-Selank Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
SNAP-8
SNAP-8 (Acetyl Octapeptide-3) is a cosmetic peptide that reduces the appearance of wrinkles by modulating muscle contraction. It is often called 'topical Botox' though it works through a different mechanism.
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.
Full details →Side-by-Side Comparison
| Aspect | SNAP-8 | NA-Selank Amidate |
|---|---|---|
| Mechanism | Mimics the N-terminal end of SNAP-25, competing with native SNAP-25 for position in the SNARE complex. This reduces neurotransmitter release at the neuromuscular junction, decreasing muscle contraction. | 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: 3-10% concentration in serums or creams, applied 1-2 times daily to target areas (forehead, crow's feet, etc.). | Intranasal: 100-400mcg 1-3 times daily. Lower doses needed compared to standard Selank due to enhanced bioavailability. |
| Administration | Topical application only. Should be applied to clean skin. Often formulated with penetration enhancers for better absorption. | Primarily intranasal administration. Can be used sublingually. More stable in solution than standard Selank. |
| Side Effects | Generally well-tolerated topically. Rare reports of mild skin irritation. No systemic effects at cosmetic doses. | Generally well-tolerated. Possible mild fatigue or nasal irritation. Less frequent dosing needed than standard Selank. |
