Are peptides safe and legal? What the FDA ruling means in the US and UK

Updated 10 August 2026. Regulatory status current as of this date. Most approved peptide medicines are legal when prescribed appropriately. But wellness and lifestyle peptides such as BPC-157, TB-500 and MOTS-c remain unapproved and unproven; the FDA’s July 2026 advisory vote did not make them approved or immediately legal to compound.
