Argireline vs Dihexa
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Argireline
Argireline (Acetyl Hexapeptide-3) is a widely-used cosmetic peptide that reduces wrinkle depth by inhibiting neurotransmitter release. One of the first 'Botox-like' peptides developed for topical use.
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 | Argireline | Dihexa |
|---|---|---|
| Mechanism | Inhibits the formation of the SNARE complex required for neurotransmitter release, reducing the intensity of muscle contractions that cause expression lines. | 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: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments. | 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 clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results. | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. |
| Side Effects | Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses. | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. |
