About this compound
TB-500
Thymosin Beta-4 actin-binding fragment
First disclosed
1966
TB-500 is a synthetic fragment of Thymosin Beta-4, an actin-sequestering protein found in eukaryotic cells. Research focus centres on cell migration and cytoskeletal-remodelling pathways.
Binds G-actin to modulate cytoskeletal dynamics; studied in vitro for endothelial cell-migration and signalling pathways.

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 peptide based on the actin-binding region of thymosin β4 (active region LKKTETQ), the actin-sequestering protein found in almost every mammalian cell. Laboratory interest centres on cell migration and cytoskeletal remodelling.
It is supplied as a 5 mg lyophilised vial, and is often studied next to BPC-157 — the BPC-157 + TB-500 blend combines both at a fixed ratio.
Store at −20 °C, protected from light. Ordered before 12:00 UK time, it ships the same day by tracked delivery. Not for human or veterinary use.

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.
Ravi M.Birmingham, UK · 1 May 2026
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.
