Is TB-500 legal to buy?

It is sold as a research chemical, not an approved drug, and it is not a legal dietary supplement in the US. The FDA took it off its Category 2 compounding list in April 2026. In July 2026 an advisory panel voted to recommend it for compounding anyway, against the agency's own reviewers, who found no data of any kind on the substance in people. It is also banned in Olympic sport.
