SNAP-8 vs Dihexa
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 →Dihexa
Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF.

| Aspect | SNAP-8 | Dihexa |
|---|---|---|
| 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. | Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway. |
| Typical Dosage | Topical: 3-10% concentration in serums or creams, applied 1-2 times daily to target areas (forehead, crow's feet, etc.). | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. |
| Administration | Topical application only. Should be applied to clean skin. Often formulated with penetration enhancers for better absorption. | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. |
| Side Effects | Generally well-tolerated topically. Rare reports of mild skin irritation. No systemic effects at cosmetic doses. | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. |
