Evidence 2/5

Indirect preclinical evidence

TB-500 claims mostly rely on thymosin beta-4 repair biology and preclinical data rather than direct human TB-500 outcome trials.

Mostly animal, ex vivo, cell, or indirect evidence.

Evidence basis

  • Thymosin beta-4 repair biology
  • Preclinical repair literature
  • Weak direct human TB-500 evidence

How to read this entry

Dose references and half-life values are pulled from trial protocols, labels, reviews, or published summaries where available. They are context for research and comparison, not a personal dosing recommendation.

Status matters: approved drugs have regulated indications; investigational compounds are still being studied; research-only peptides do not have established human dosing, safety, or efficacy for consumer use.
