BNP (B-type Natriuretic Peptide) vs Ipamorelin

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.

Ipamorelin

Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.

Side-by-Side Comparison

Aspect	BNP (B-type Natriuretic Peptide)	Ipamorelin
Dose Range	25 mcg–100 mcg	100 mcg–300 mcg
Frequency	1x daily	2x daily
Cycle Length	1–4 weeks	8–12 weeks
Route	subcutaneous	subcutaneous
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 ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones.
Typical Dosage	Nesiritide (recombinant BNP): 2mcg/kg IV bolus followed by 0.01mcg/kg/min continuous infusion for acute decompensated heart failure.	Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295.
Administration	Intravenous administration only. Used in acute care settings for heart failure. BNP levels also used diagnostically.	Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides.
Side Effects	Hypotension (common and dose-limiting), headache, nausea, and potential renal function worsening in some patients.	Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially.
