TB-500 for soft-tissue recovery: what the animal data suggests (and does not)

After a tendon injury I went down the TB-500 rabbit hole and tried to read the actual literature rather than the forum lore. TB-500 is a fragment related to thymosin beta-4, and most of what exists is animal work on actin regulation, cell migration, and wound models.

The honest summary: the preclinical rationale is interesting, but there are no human efficacy trials for the TB-500 fragment itself. I am treating it as Tier 3 and keeping my expectations calibrated to that. Would love to hear how others weigh animal-only evidence.

Important nuance: the TB-500 fragment is not the same as full-length thymosin beta-4, which is the molecule that has actually entered early human trials. Conflating the two inflates the apparent evidence.

Calibrating expectations to Tier 3 is exactly the right move. The animal data are interesting but they are not a human result.
