Semax 5 mg vial
Prices from 9 vendors.
Read the regulatory status before you compare prices.
Semax is approved and prescribed in Russia. It has never been approved in the United States. On July 24, 2026, an FDA advisory committee voted by a narrow margin to recommend adding Semax to the list of substances US pharmacies may compound. The FDA's own scientific reviewers had advised against it. The vote is advice, not a decision, and compounding Semax is still not legal in the US today.
