BNP (B-type Natriuretic Peptide) vs GHRP-6
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 →GHRP-6
Growth Hormone Releasing Peptide 6 (GHRP-6) is one of the first synthetic growth hormone secretagogues discovered. It stimulates significant GH release but is known for causing intense hunger.
Full details →Side-by-Side Comparison
| Aspect | BNP (B-type Natriuretic Peptide) | GHRP-6 |
|---|---|---|
| Mechanism | Similar to ANP - activates NPR-A receptors to produce vasodilation, natriuresis, and RAAS suppression. Released in response to ventricular wall stress. | Acts as a ghrelin mimetic, binding to the GHS-R receptor in the pituitary and hypothalamus. Stimulates GH release and also significantly increases appetite by mimicking ghrelin's hunger-signaling effects. |
| Typical Dosage | Nesiritide (recombinant BNP): 2mcg/kg IV bolus followed by 0.01mcg/kg/min continuous infusion for acute decompensated heart failure. | Typical dosing: 100-300mcg administered 2-3 times daily. Often combined with GHRH peptides like CJC-1295 for synergistic effects. |
| Administration | Intravenous administration only. Used in acute care settings for heart failure. BNP levels also used diagnostically. | Subcutaneous injection. Best administered on an empty stomach. The strong hunger response can be beneficial for those trying to gain weight but challenging for cutting. |
| Side Effects | Hypotension (common and dose-limiting), headache, nausea, and potential renal function worsening in some patients. | Intense hunger (most notable effect), water retention, increased cortisol and prolactin, tingling/numbness, and potential blood pressure changes. |
