Bodybuilders use TB-500 peptide for faster exercise recovery

Bodybuilders and gym enthusiasts are reportedly using the peptide TB-500 for faster exercise recovery. TB-500 mimics thymosin beta-4, a natural protein that signals tissue repair by binding to actin, potentially accelerating cell movement and healing. The FDA is reviewing TB-500 and six other peptides for potential use in wound healing, with a decision expected after an advisory panel meeting on July 23-24, 2026.
