SNAP-8 vs PE-22-28
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 →PE-22-28
PE-22-28 is a synthetic peptide fragment derived from research on the SAMP8 mouse model of accelerated aging. It has shown potential for enhancing memory and reducing cognitive decline.

| Aspect | SNAP-8 | PE-22-28 |
|---|---|---|
| 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. | Derived from the protein that is deficient in SAMP8 mice. May work by inhibiting protein phosphatase 2A methylesterase, thereby affecting memory-related signaling pathways. |
| Typical Dosage | Topical: 3-10% concentration in serums or creams, applied 1-2 times daily to target areas (forehead, crow's feet, etc.). | Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established. |
| Administration | Topical application only. Should be applied to clean skin. Often formulated with penetration enhancers for better absorption. | Intranasal administration preferred for CNS delivery. Research compound with limited human use data. |
| Side Effects | Generally well-tolerated topically. Rare reports of mild skin irritation. No systemic effects at cosmetic doses. | Very limited human data. Primarily studied in animal models for safety and efficacy. |
