Leuphasyl vs Dihexa
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Leuphasyl
Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.
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.
Full details →Side-by-Side Comparison
| Aspect | Leuphasyl | Dihexa |
|---|---|---|
| Mechanism | Mimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity. | 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: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides. | 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 to expression lines. Best results with consistent twice-daily use over 8+ weeks. | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. |
| Side Effects | Very well-tolerated topically. No significant adverse effects reported at cosmetic concentrations. | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. |
