SNAP-8 vs LL-37 (Cathelicidin)
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 →LL-37 (Cathelicidin)
LL-37 is the only human cathelicidin antimicrobial peptide. It plays crucial roles in innate immunity and has shown diverse biological activities including antimicrobial, immunomodulatory, and wound healing properties.
Full details →Side-by-Side Comparison
| Aspect | SNAP-8 | LL-37 (Cathelicidin) |
|---|---|---|
| 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. | Disrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects. |
| 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 widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections. |
| Administration | Topical application only. Should be applied to clean skin. Often formulated with penetration enhancers for better absorption. | Subcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols. |
| Side Effects | Generally well-tolerated topically. Rare reports of mild skin irritation. No systemic effects at cosmetic doses. | Injection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses. |
