About TB-500

TB-500 is a synthetic fragment of thymosin beta-4, the actin-binding protein that appears in wound fluid and is studied for its role in cell migration and angiogenesis. The published record is preclinical and mostly focused on dermal wound closure, corneal repair and cardiac remodelling after ischaemic injury in animal models. Human data is essentially absent, and the compound sits on WADA's prohibited list, so it is supplied strictly for laboratory research. Our evidence grade of emerging reflects a coherent mechanism with a thin and largely single-species literature behind it.

Buyers routinely confuse TB-500 with full-length thymosin beta-4, and some suppliers do nothing to correct the confusion. The fragment is cheaper to synthesise and far more common on the research market; the full protein is a different product with a different price. Check the sequence stated on the certificate rather than the name on the label, because two listings on this page can carry the same product name and contain different molecules.

What moves the TB-500 price

Synthesis length drives most of the cost here, which is why the range between the cheapest and median 5mg vial is narrower than on metabolic peptides. Where suppliers do separate themselves is in peptide content versus gross vial weight, in the reliability of cold-chain handling during warm months, and in whether reconstitution guidance and a batch certificate ship with the order. Price per milligram is the honest comparison, and a vial that looks five pounds cheaper often carries noticeably less actual peptide once the excipient share is accounted for.

How we independently rank every supplier

The ranking on this page is produced independently of the suppliers listed. Placement cannot be bought, sponsored or negotiated, and we do not accept payment to suppress a low score. Each supplier earns a mark out of ten built from published third-party analysis, verification of the legal identity behind the domain, moderated customer reviews submitted through CheckALab, and fulfilment signals including dispatch speed, stock accuracy and complaint resolution.

Because TB-500 is frequently mislabelled, our documentation check for this product tests whether the certificate states the actual fragment sequence rather than a generic product name. Suppliers that publish sequence-level data score better than those publishing purity alone. Reviews are only counted after moderation and are blended slowly, so no single burst of feedback can reposition a supplier. Every score is recalculated as fresh certificates and delivery data arrive, which means the order of this table changes over time without any supplier being able to influence it.

How to buy TB-500 cheaply without cutting corners

The lowest headline price is rarely the best value. Compare price per mg rather than price per vial, check whether a batch-matched certificate of analysis is published, and factor in delivery. A cheap vial with no third-party testing behind it is not a saving.

Kensington Labs currently sits at the top of this table at £24 for a 5mg vial, and holds a CheckALab score of 9.43/10.
