TB-500
Thymosin Beta-4 Fragment - Thymosin β-4 fragment studied for actin regulation and tissue repair.
TB-500 is a synthetic version of the naturally occurring peptide Thymosin β-4. Research interest centres on its regulation of actin, cell migration and its reported role in tissue-repair and flexibility models.
As a synthetic form of the naturally occurring Thymosin β-4, TB-500 is studied less for a single receptor and more for its upstream effect on the actin cytoskeleton, which touches migration, angiogenesis and flexibility endpoints. It is a common comparator and combination partner in tissue-repair protocols alongside BPC-157.

Reported mechanisms in the literature
- Actin regulation - As a synthetic form of Thymosin β-4, it is studied for binding and sequestering G-actin - a mechanism linked to cell migration and tissue remodelling in repair research. (Goldstein et al.)
- Reparative cell recruitment - Investigated for directing reparative and endothelial cells toward sites of tissue stress, and for its reported role in flexibility and recovery models. (Sosne et al.)
TB-500 frequently asked questions
Is TB-500 the same as Thymosin β-4?
TB-500 is a synthetic version of the naturally occurring peptide Thymosin β-4. Some suppliers instead sell a shorter active fragment; ours is documented on the lot COA. It is a research material only.
Is TB-500 approved for human use?
No. It has no regulatory approval for human use and is not a medicine or supplement. All available data is preclinical. It is supplied for in-vitro laboratory research only.
What is TB-500 studied for?
Chiefly actin regulation, cell migration and tissue-repair signalling in animal and cell models. Findings are preclinical and do not describe effects in humans.
