BNP (B-type Natriuretic Peptide) vs Palmitoyl Tetrapeptide-7
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
BNP (B-type Natriuretic Peptide)
BNP is a cardiac neurohormone released primarily by ventricles in response to volume/pressure overload. It's a major biomarker for heart failure and has therapeutic applications as nesiritide.
Full details →Palmitoyl Tetrapeptide-7
Palmitoyl Tetrapeptide-7 is an anti-inflammatory peptide that reduces IL-6 secretion. Combined with Palmitoyl Tripeptide-1, it forms Matrixyl 3000, addressing both collagen production and inflammation.
Full details →Side-by-Side Comparison
| Aspect | BNP (B-type Natriuretic Peptide) | Palmitoyl Tetrapeptide-7 |
|---|---|---|
| Mechanism | Similar to ANP - activates NPR-A receptors to produce vasodilation, natriuresis, and RAAS suppression. Released in response to ventricular wall stress. | Suppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides. |
| Typical Dosage | Nesiritide (recombinant BNP): 2mcg/kg IV bolus followed by 0.01mcg/kg/min continuous infusion for acute decompensated heart failure. | Topical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex. |
| Administration | Intravenous administration only. Used in acute care settings for heart failure. BNP levels also used diagnostically. | Topical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin. |
| Side Effects | Hypotension (common and dose-limiting), headache, nausea, and potential renal function worsening in some patients. | Excellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin. |
