TB-500 is a synthetic fragment of the naturally occurring protein thymosin beta-4, supplied by MyPeptides for laboratory research use only.
TB-500 is a synthetic fragment of thymosin beta-4, the actin-sequestering protein studied in cell-migration and wound-healing research. It's one of the two backbone peptides — alongside BPC-157 — of the healing-research shelf.
Supplied lyophilised, HPLC assayed at ≥99%, CAS 885340-08-9, molecular formula C38H68N10O14. Store at −20 °C and reconstitute in sterile diluent for in vitro protocols.
Labs running comparative repair studies typically pair it with BPC-157 — the BPC-157 + TB-500 blend fixes the ratio in a single vial for reproducibility.

Fast UK shipping
Support answered a batch question within a few hours over email. Rare to get that level of response from a research supplier. Product itself is exactly to spec.

Solid product, will reorder
Everything about this feels professional - from the site to the packaging to the paperwork. Purity assay matches what is on the label. Will keep ordering.

Reference-grade quality
The little details matter - proper cold-chain, tamper-evident seals, and a CoA that actually reads like a lab report and not a marketing sheet.

Consistent batch to batch
Ordered late Monday, arrived Wednesday morning in the UK. Packaging was cold-protected and every vial sealed correctly. CoA matched the batch number on the label.
