ANP (Atrial Natriuretic Peptide) vs Argireline
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
ANP (Atrial Natriuretic Peptide)
ANP is a cardiac hormone released by atrial myocytes in response to stretch. It promotes natriuresis, diuresis, and vasodilation, playing key roles in blood pressure and fluid regulation.

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.

| Aspect | ANP (Atrial Natriuretic Peptide) | Argireline |
|---|---|---|
| Mechanism | Binds to natriuretic peptide receptors (NPR-A) to activate guanylyl cyclase, producing cGMP. This leads to vasodilation, increased kidney filtration, and inhibition of the renin-angiotensin-aldosterone system. | Inhibits the formation of the SNARE complex required for neurotransmitter release, reducing the intensity of muscle contractions that cause expression lines. |
| Typical Dosage | Clinical use: Carperitide (recombinant ANP) used in Japan for acute heart failure at 0.1mcg/kg/min IV infusion. | Topical: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments. |
| Administration | Intravenous infusion only for clinical applications. Short half-life (~2 minutes) requires continuous administration. | Topical application to clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results. |
| Side Effects | Hypotension (dose-limiting), headache, nausea, and potential arrhythmias at high doses. | Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses. |
