Identity & specification

Sequence and acetylation status remain unconfirmed for this listing. Ac-LKKTETQ and full-length thymosin beta-4 are different materials; the name TB-500 alone does not resolve identity.

Laboratory research only

Not for human or veterinary administration. Listed strength is a supplied specification; see the matching batch report for measured results.

UNDERSTAND THE COMPOUND

What is TB-500?

An analytical study identified Ac-LKKTETQ, the acetylated seven-amino-acid fragment corresponding to residues 17–23 of thymosin beta-4, in material sold as TB-500. This fragment is distinct from the full-length thymosin beta-4 peptide. A 2024 study followed the fragment and its metabolites in laboratory systems and rats, then compared their activity in a fibroblast wound-closure assay. Significant activity in that assay was reported for the metabolite Ac-LKKTE, rather than the parent TB-500. The findings make chemical identity central to interpreting the literature and do not support transferring full-length thymosin beta-4 outcomes to the fragment.

Studies & research references

Each source identifies what was studied and the limits of its findings. Published research is separate from this product’s batch COA.

Analytical identity study

Identification of the acetylated thymosin beta-4 fragment in TB-500 (2012)

Chromatography and mass spectrometry identified Ac-LKKTETQ in the tested TB-500 material. The study established an analytical identity, not therapeutic efficacy.

Analytical, animal & cell study

TB-500 metabolites and fibroblast wound-closure activity (2024)

Researchers measured the fragment and its metabolites in experimental systems and rats. Only Ac-LKKTE showed significant wound-closure activity in the reported fibroblast assay.
