AHK-Cu vs BNP (B-type Natriuretic Peptide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
AHK-Cu
AHK-Cu (Copper Tripeptide-3, Alanine-Histidine-Lysine Copper) is a copper peptide similar to GHK-Cu but with different properties. It's used for hair growth and skin rejuvenation applications.
Full details →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.

| Aspect | AHK-Cu | BNP (B-type Natriuretic Peptide) |
|---|---|---|
| Mechanism | The copper-binding tripeptide stimulates collagen synthesis and may promote hair follicle enlargement. Works similarly to GHK-Cu but may have distinct receptor interactions. | Similar to ANP - activates NPR-A receptors to produce vasodilation, natriuresis, and RAAS suppression. Released in response to ventricular wall stress. |
| Typical Dosage | Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations. | Nesiritide (recombinant BNP): 2mcg/kg IV bolus followed by 0.01mcg/kg/min continuous infusion for acute decompensated heart failure. |
| Administration | Topical application to skin or scalp. Can be used with microneedling for enhanced penetration. May cause temporary blue-green tint at high concentrations. | Intravenous administration only. Used in acute care settings for heart failure. BNP levels also used diagnostically. |
| Side Effects | Generally well-tolerated. May cause skin irritation in sensitive individuals. Temporary discoloration possible. | Hypotension (common and dose-limiting), headache, nausea, and potential renal function worsening in some patients. |
