Is thymalin FDA approved?
No. It is not FDA approved. It was not among the seven peptides the FDA's Pharmacy Compounding Advisory Committee reviewed at its July 2026 meeting, unlike BPC-157, TB-500, and MOTS-c. Its history of use by doctors is limited to the Soviet Union and Russia, and it has not gone through the study and review process any Western regulator requires.
