No approval. No published human study.
As of September 2026, no TB-500 medicine is approved in the US.
The FDA, short for Food and Drug Administration, found no published human study of TB-500 in its checked review.
The unknown effects are a gap in the evidence, not proof that nothing can go wrong.
What that means for a visit
Ask about the concern first.
You can arrive at a visit without having chosen a treatment. Explain your concern and what you want to learn from the visit.
- Ask which care options fit the problem.
- Ask for the evidence behind each option.
- Ask what the visit costs even if no medicine is offered.
- Ask who will answer questions after the visit.
What supports using this for my problem?
For TB-500, FDA found no published study in people as of the September 2026 check.
If the answer points to thymosin beta-4 research, ask why a finding for a different substance is being used.
