Where to Buy TB-500 for Research
Sourcing TB-500 for sale for laboratory research? The supplier matters as much as the compound. This guide covers how to verify purity, read a batch certificate of analysis, evaluate vendors, and what to expect on price — then where to buy TB-500 that ships same-day from Houston, Texas.

What TB-500 is (research context)
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring actin-binding peptide. It is widely used in cell-migration, tissue-repair, and angiogenesis research. Because potency depends heavily on correct sequence and purity, batch-level verification is critical. It is supplied as a lyophilized powder for in vitro laboratory research only. For the underlying science, see our TB-500 research overview.
What to look for when buying TB-500
Research peptides are an unregulated category, so quality varies enormously between suppliers. Five things separate verified material from a gamble:
- HPLC purity (ideally ≥99%). If a supplier won't show the chromatogram, treat it as a red flag.
- LC-MS identity confirmation. Purity alone doesn't prove the vial contains TB-500 — mass spec confirms molecular identity.
- Endotoxin (LAL) testing. Contamination can confound cell-based work; results should appear on the COA.
- A batch-specific COA matching the exact lot on your vial. How to read a peptide COA →
- Domestic, cold-chain shipping to protect the material in transit.

How to verify a TB-500 COA
A trustworthy supplier makes verification easy. Lone Star publishes every batch COA in a public, searchable library — so before you buy you can confirm the HPLC purity, LC-MS identity, and endotoxin results for the exact lot. If a supplier can't show a batch-matched report from a named independent lab, be cautious.
What TB-500 pricing looks like
Research TB-500 is priced by vial size, with per-vial cost dropping on larger orders. Be wary of pricing far below market — unusually cheap material often signals under-dosed or unverified product. Current sizes and live pricing are on the TB-500 product page.
