Selank vs SNAP-8
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Selank
Selank is a synthetic peptide derived from the naturally occurring immunomodulatory peptide tuftsin. Developed in Russia for anxiety and cognitive enhancement.
Full details →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 →Side-by-Side Comparison
| Aspect | Selank | SNAP-8 |
|---|---|---|
| Dose Range | 300 mcg–900 mcg | 500 mcg–1 mg |
| Frequency | 2x daily | 1x daily |
| Cycle Length | 2–4 weeks | 4–8 weeks |
| Route | intranasal | topical |
| Mechanism | Modulates the expression of brain-derived neurotrophic factor (BDNF) and affects serotonin and norepinephrine systems. Has immunomodulatory and anxiolytic properties. | 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. |
| Typical Dosage | Intranasal administration: 250-500mcg 2-3 times daily. Subcutaneous: 250-500mcg daily. | Topical: 3-10% concentration in serums or creams, applied 1-2 times daily to target areas (forehead, crow's feet, etc.). |
| Administration | Most commonly administered intranasally for cognitive effects. Can also be injected subcutaneously. | Topical application only. Should be applied to clean skin. Often formulated with penetration enhancers for better absorption. |
| Side Effects | Generally well-tolerated. Some users report mild fatigue or nasal irritation with intranasal use. | Generally well-tolerated topically. Rare reports of mild skin irritation. No systemic effects at cosmetic doses. |
