What this means

  • 01

    No product containing ANP is approved by FDA for any use in the United States, so nothing on the market is authorized for people.

  • 02

    "Research use only" is a vendor label, not a legal category that permits human use. It does not exempt a product from medicines law.

  • 03

    Importing, supplying or promoting it for human use can fall under medicines legislation in the United States. This page is general information, not legal advice.

What ANP is

The hormone the heart releases when its chambers stretch, and the reason the heart counts as an endocrine organ. Its recombinant form, carperitide, is used for acute heart failure in Japan; a 2025 meta-analysis of 9 studies found higher in-hospital mortality in carperitide-treated patients when randomised and propensity-matched studies were pooled.

Atrial natriuretic peptide is a 28 amino acid peptide, sequence SLRRSSCFGGRMDRIGAQSGLGCNSFRY, released from atrial cells when the chamber wall is stretched. It makes the kidney excrete sodium and water, relaxes blood vessels and opposes the renin-angiotensin system.

Mechanism: In humans, ANP binds NPR-A (gene NPR1), a particulate guanylyl cyclase, raising cyclic GMP in vascular smooth muscle and kidney tubule cells. The results are natriuresis, diuresis and vasodilation, plus suppression of renin and aldosterone.

Regulatory history: Not FDA approved. No ANP or carperitide product was returned by the Drugs@FDA query on 11 September 2026. Carperitide is described in the clinical literature as in use for acute heart failure in Japan; this site did not verify that approval with the Japanese regulator and does not state its date or terms.

How FDA treats this kind of product

Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.

The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for ANP at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
