Is TB-500 legal to buy?

TB-500 is among the peptides under FDA review for the Category 1 (503A) bulk-substances list — removed from Category 2 in April 2026 but not yet on a finalized Category 1 list. The FDA PCAC committee meets July 23–24, 2026 to make recommendations on which peptides may be compounded, and under what conditions — the PCAC is advisory only, and the FDA would issue any final rule on a separate, later timeline. If a final rule is ultimately issued, a valid prescription from a licensed prescriber may be required for compounding access; timing is uncertain. Current sales are for research purposes only.
