Ipamorelin vs ANP (Atrial Natriuretic Peptide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →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.

| Aspect | Ipamorelin | ANP (Atrial Natriuretic Peptide) |
|---|---|---|
| Mechanism | 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. | 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. |
| Typical Dosage | Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295. | Clinical use: Carperitide (recombinant ANP) used in Japan for acute heart failure at 0.1mcg/kg/min IV infusion. |
| Administration | Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides. | Intravenous infusion only for clinical applications. Short half-life (~2 minutes) requires continuous administration. |
| Side Effects | Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially. | Hypotension (dose-limiting), headache, nausea, and potential arrhythmias at high doses. |
