This is a dated editorial summary, not a live FDA check or independent medical review. It does not recommend treatment or verify a product in hand.

Status: No FDA-approved TB-500 drug product

Exact product limits: TB-500 is not the same as the full thymosin beta-4 molecule. FDA identifies TB-500 as a seven-amino-acid fragment, not as interchangeable with full-length thymosin beta-4. Internet naming and certificates do not establish product identity or clinical equivalence.

Human outcomes: Unclear. FDA found no adequate human clinical outcome evidence for compounded TB-500 wound-healing use.

Body effects in people: Limited. Fragment identity and laboratory findings do not establish a clinical benefit in people.

What the evidence shows: FDA has published a detailed 2026 briefing on TB-500's identity, characterization, proposed wound-healing use, and evidence gaps. WADA explicitly names TB-500 on the 2026 Prohibited List.

What remains unknown: Reliable controlled studies in people do not establish faster tendon, muscle, or wound healing from TB-500. Safety, purity, sterility, long-term effects, and equivalence of marketed material remain uncertain.

Safety limits: This is not an invitation to experiment. The guide provides no sourcing, reconstitution, injection, cycle, stack, or injury-treatment instructions.
