Peptide legal status/Kisspeptin-10

Legal status · Record reviewed August 30, 2026

Is Kisspeptin-10 legal in the U.S.?

Short answer

Kisspeptin-10 has no single legal status. It depends on the product and how it is supplied.

No FDA-approved Kisspeptin-10 product was identified in the United States as reviewed August 30, 2026. A research use only label does not make a product approved for people.

Pharmacy mixing (compounding): FDA lists it in Category 2 for possible safety risks (FDA page dated April 22, 2026).

Sports: the anti-doping rules we checked list it as prohibited (checked August 30, 2026). Applies to male athletes only.

Rules for buying, selling, and prescribing also depend on how a product is made and sold, and on state law.

This is not legal advice.

Whether you may buy, sell, or use a product also depends on pharmacy (compounding) rules, a prescription, and state law. Read how U.S. peptide law works.
