Is Semax legal?
Not as a drug. Semax has no FDA approval, so selling it for human use breaks federal drug law, and a 'research use only' label does not protect a seller whose site signals human use. It is not a controlled substance, and possessing it is not a federal crime. It is approved in Russia, which has no effect in the US. An FDA advisory committee recommended it for pharmacy compounding in July 2026, but FDA has not acted, so pharmacies still cannot compound it.

State rules
1 STATESince 1 Jul 2026 Indiana law (IC 16-42-22.5) bars compounding from research-grade or veterinary-grade bulk ingredients outside an IRB-approved study and requires an FDA-registered source with a certificate of analysis. From 1 Jan 2027 medical spas must register with the state medical board. This matters if FDA later allows pharmacies to compound Semax: in Indiana the ingredient could not be research grade.
