Snap-8

Snap-8 in the T&T Supplies peptide lexicon: research reference with mechanism, reported effects, limitations and literature data. Evidence grade C+.

Mechanism

Synthetic octapeptide that mimics N-terminal portion of SNAP-25. Inhibits SNARE complex formation → reduced acetylcholine release at local neuromuscular junctions → reduced muscle contraction intensity in expression lines.

Reported effects

Reduces expression-related fine lines without injection. Can be added to moisturizer or serum. No systemic effects. Safe topical profile.

Limitations

Penetration through skin is very limited for large peptides. Most human evidence industry-funded. Effects subtle vs Botox.

Literature data

Dosage (literature)

2-10% topical solution, apply 2× daily

Timing

Morning and evening skincare routine

Cycling

Continuous — topical peptides require sustained use
