TB-500 (Thymosin Beta-4 Acetate)
Healing & Recovery
TB-500 is a synthetic version of thymosin beta-4, a 43-amino-acid protein found in nearly every human cell and especially high in platelets and wound fluid. Its main job is to bind actin, the protein that forms the cell's internal frame, which helps cells move to injured areas. In animal studies it has been linked to faster wound healing, new blood vessel growth, less inflammation and repair of heart and eye tissue. Small human trials of thymosin beta-4 have looked at eye-surface injuries and skin ulcers. Controlled trials of TB-500 itself have not been published. It is studied in tissue repair, heart and inflammation models.

Ships dry. This vial contains a lyophilized (freeze-dried) powder, so bacteriostatic water is needed to reconstitute it before use. Bacteriostatic water is available separately under Supplies.
What the research reports
Published findings · not a claim about any individual outcome
- Animal studies report faster wound closure, reduced scarring and improved heart-muscle repair after induced injury.
- Human trials of thymosin beta-4 in dry eye and venous ulcers reported modest improvements in healing and symptom scores.
- Effects are attributed to actin binding and cell migration. No human trials in tendon, muscle or athletic recovery exist.
