TB-500 is frequently mentioned in the same breath as BPC-157, and the two are often discussed together for recovery. They are not the same thing and they do not work the same way. TB-500 is a synthetic version of a naturally occurring peptide involved in cell migration and tissue organization. At Body Works it is compounded and used under provider supervision.
TB-500 is a synthetic fragment of thymosin beta-4, a protein present in nearly every human cell and found in high concentration at sites of injury. The fragment used in TB-500 corresponds to the region believed to carry the repair-related activity.
Its defining mechanism involves actin, one of the primary proteins of the cellular skeleton. By binding actin, thymosin beta-4 influences how cells move, which is fundamental to how tissue reorganizes itself during healing.
Preclinical research has examined thymosin beta-4 in wound healing, cardiac tissue after injury, and corneal repair. The recurring theme is cell migration: healing requires the right cells to move into the right place, and that process depends on the actin cytoskeleton.
Patients typically raise TB-500 in the context of soft tissue recovery and range of motion. As with BPC-157, human clinical trial evidence is limited and the honest framing is a developing evidence base rather than established human therapy.
TB-500 is not FDA-approved. It is prepared by compounding pharmacies and is also prohibited in sanctioned athletic competition, which is worth knowing if you compete under any anti-doping authority.
Body Works uses TB-500 only under provider supervision, with candidacy assessed individually and the regulatory and competition implications explained before you begin.

TB-500 is a synthetic fragment of thymosin beta-4, a protein found in nearly every human cell and concentrated at injury sites. It binds actin, a primary protein of the cellular skeleton, influencing how cells migrate during tissue repair and reorganization.
They are often discussed together but work differently. BPC-157 is a fragment of a gastric protein studied for repair signaling and gut integrity. TB-500 is a thymosin beta-4 fragment that acts on the actin cytoskeleton and cell migration. Your provider will explain which mechanism fits your goal.
No. TB-500 is not FDA-approved. It is prepared by compounding pharmacies and used under provider supervision at Body Works, with candidacy assessed individually.
TB-500 is prohibited in sanctioned athletic competition under anti-doping authorities. If you compete under any such body, tell your provider before considering TB-500, because it would put your eligibility at risk.
TB-500 is given by subcutaneous injection. Your provider determines the protocol based on your goals and history, and demonstrates the injection technique at your visit.
