What is TB-500?
TB-500 is a synthetic fragment of thymosin beta-4, a protein involved in cell movement and repair; the FDA identifies it by the seven-amino-acid sequence LKKTETQ. Interest comes from animal studies and from research on the parent protein. TB-500 itself has no human trials, so it is offered with that said plainly, as an adjunct to rehabilitation rather than a substitute for it.
Who asks about TB-500?
Active adults with a soft-tissue or tendon problem who want physician oversight and accept that human evidence is missing.
- A soft-tissue or tendon problem already being rehabilitated
- Want oversight rather than research-grade products online
- Not a tested athlete
- Understand there are no human trials
TB-500: what is known and what is not
The honest summary is short.
Evidence. Animal and parent-protein data are promising; there are no human trials of TB-500.
Safety. The FDA reports no identified human exposure data and has flagged compounded TB-500 for immune reactions and impurities.
Status. Never FDA-approved for any use, so prescribing it is unapproved, not off-label.
How TB-500 is used here
Alongside rehab. An adjunct to physical therapy and recovery work, never instead of it.
Physician supervision. Prescribed only after an evaluation, with the evidence explained.
Other options weighed. PRP and shockwave have their own evidence and are considered at the same visit.
Follow-up. Your provider decides with you whether to continue.
