Question 1

What is TB-500?

Accepted Answer

A synthetic fragment corresponding to the active actin-binding region of thymosin beta-4, a naturally occurring protein.

Question 2

Is it the same as thymosin beta-4?

Accepted Answer

No. Thymosin beta-4 is the full 43-residue protein; TB-500 is a shorter fragment of it. Suppliers often conflate the two.

Question 3

What does actin sequestering mean?

Accepted Answer

It binds free actin monomers, shifting the balance between loose monomers and assembled filaments — the balance cells rely on to move.

Question 4

Why is it often paired with BPC-157?

Accepted Answer

Because their reported mechanisms differ. One acts on the cytoskeleton, the other on vessel formation and growth-factor pathways, so they are studied as complements.

Question 5

Is there human research?

Accepted Answer

Thymosin beta-4 itself has been studied clinically in wound healing. TB-500 as a research peptide has no controlled human trial data, and it is not approved anywhere.

Question 6

Is it prohibited in sport?

Accepted Answer

Yes, it appears on the World Anti-Doping Agency prohibited list.
