TB-500 evidence check
TB-500 speeds soft tissue recovery in humans.
Verdict
Overhyped with an evidence grade of D. The available evidence found here is mostly about thymosin beta-4 biology and clinical exploration, not direct proof that consumer TB-500 products speed soft-tissue recovery in humans.
What this means
This grade applies only to the claim on this page, including the stated population and outcome. A supported claim in one context should not be stretched into a broader peptide promise.
What this does not mean
This page is not dosing guidance, a protocol, a recommendation to buy or use a product, or personal medical advice. High-risk claims need narrow wording, source links, and human review before publication.
Source trail
Evidence is listed by source type so you can see whether the claim rests on labeling, human studies, preclinical work, anecdotes, or vendor language.
