ANP (Atrial Natriuretic Peptide) vs Hexarelin

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

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.

Hexarelin

Hexarelin is a potent synthetic hexapeptide growth hormone secretagogue. It provides the strongest GH release among GHRPs but is associated with rapid desensitization of receptors.

Side-by-Side Comparison

Aspect	ANP (Atrial Natriuretic Peptide)	Hexarelin
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	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.	Acts as a ghrelin mimetic with high potency at the GHS receptor. Provides powerful GH release but receptor desensitization occurs faster than with other GHRPs, requiring cycling.
Typical Dosage	Clinical use: Carperitide (recombinant ANP) used in Japan for acute heart failure at 0.1mcg/kg/min IV infusion.	Typical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization.
Administration	Intravenous infusion only for clinical applications. Short half-life (~2 minutes) requires continuous administration.	Subcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols.
Side Effects	Hypotension (dose-limiting), headache, nausea, and potential arrhythmias at high doses.	Water retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects.
