Is Angiotensin II legal in the United States?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Yes. Angiotensin II is an approved medicine in the United States, classified as "FDA-approved, prescription only". Approval covers its labeled indication and it is supplied on prescription, not over the counter. Products labeled "research use only" fall outside that approval and the label does not make human use lawful. On the evidence, 5 human studies are cited on its profile.

What this means
- 01
FDA has approved Angiotensin II for at least one labeled indication, so a pharmaceutical-grade product exists in the United States and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What Angiotensin II is
The body's main blood-pressure hormone, approved as an intravenous drug for shock that no longer responds to standard vasopressors. Its pivotal trial in 344 people met a blood-pressure endpoint; death by day 28 was 46 percent on angiotensin II and 54 percent on placebo, a difference that was not statistically significant.
Angiotensin II is an 8 amino acid peptide, sequence DRVYIHPF, cut out of angiotensinogen by renin and then by angiotensin-converting enzyme. It is the business end of the renin-angiotensin system: it constricts blood vessels, drives aldosterone release and promotes sodium retention.
Mechanism: In humans, angiotensin II binds the AT1 receptor on vascular smooth muscle to cause vasoconstriction, and on the adrenal cortex to release aldosterone, which retains sodium and water. The AT2 receptor generally opposes those effects.
Regulatory history: FDA approved 21 December 2017 (GIAPREZA, NDA 209360) to increase blood pressure in adults with septic or other distributive shock. Prescription only, intravenous. A generic angiotensin II acetate injection was approved 3 June 2025 (ANDA 216966).
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 Angiotensin II 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.

Can I buy Angiotensin II in the United States?
Only with a prescription. Angiotensin II is classified as "FDA-approved, prescription only" in the United States, so it is dispensed by pharmacies against a prescription for its approved indication. Buying it from unlicensed online sellers or as a "research chemical" is outside that system and carries no regulatory protection. Note: GIAPREZA, NDA 209360, approved 21 December 2017; on the 11 September 2026 Drugs@FDA query two presentations were Prescription and one was Discontinued, and a generic was approved in June 2025.
Is Angiotensin II FDA approved?
Yes. FDA status: FDA approved 21 December 2017 (GIAPREZA, NDA 209360) to increase blood pressure in adults with septic or other distributive shock. Prescription only, intravenous. A generic angiotensin II acetate injection was approved 3 June 2025 (ANDA 216966).. Current US classification: "FDA-approved, prescription only". On the evidence, 5 human studies are cited on its profile.
