ANP (Atrial Natriuretic Peptide) vs Matrixyl
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.

Matrixyl (Palmitoyl Pentapeptide-4) is a signal peptide that stimulates collagen and extracellular matrix production. It is one of the most well-studied anti-aging peptides with proven efficacy for wrinkle reduction.

| Aspect | ANP (Atrial Natriuretic Peptide) | Matrixyl |
|---|---|---|
| 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. | Mimics collagen breakdown fragments, triggering fibroblasts to produce new collagen, elastin, and other matrix components. Essentially tricks skin into repair mode without actual damage. |
| Typical Dosage | Clinical use: Carperitide (recombinant ANP) used in Japan for acute heart failure at 0.1mcg/kg/min IV infusion. | Topical: 2-8% concentration in serums and creams. Matrixyl 3000 combines it with Palmitoyl Tetrapeptide-7 for enhanced effects. |
| Administration | Intravenous infusion only for clinical applications. Short half-life (~2 minutes) requires continuous administration. | Topical application 1-2 times daily. Can be combined with other actives like retinol, vitamin C, and other peptides. |
| Side Effects | Hypotension (dose-limiting), headache, nausea, and potential arrhythmias at high doses. | Very well-tolerated. Rare mild irritation. Suitable for sensitive skin types. |
