ANP (Atrial Natriuretic Peptide) vs Dihexa
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.
Full details →Dihexa
Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF.

| Aspect | ANP (Atrial Natriuretic Peptide) | Dihexa |
|---|---|---|
| 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 hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway. |
| Typical Dosage | Clinical use: Carperitide (recombinant ANP) used in Japan for acute heart failure at 0.1mcg/kg/min IV infusion. | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. |
| Administration | Intravenous infusion only for clinical applications. Short half-life (~2 minutes) requires continuous administration. | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. |
| Side Effects | Hypotension (dose-limiting), headache, nausea, and potential arrhythmias at high doses. | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. |
