TB-500 — research catalogue reference

It is listed here as a laboratory reference material for in-vitro research only and is not offered for human or veterinary use. Regulatory status is not determined by a research-use label; see the compliance page for official TGA guidance.

The thymosin beta-4 and TB-500 literature is largely preclinical: cell-culture and animal-model studies examining actin sequestration, cell migration, angiogenesis-related signalling, and models of dermal, corneal and cardiac tissue repair.

Human clinical evidence for the synthetic fragment specifically is limited, and we make no claims about effects in humans. The primary sources are linked at the bottom of this page so you can assess methodology and endpoints yourself.

TB-500 and BPC-157 are frequently discussed together in tissue-repair research, but they are structurally unrelated and are studied through different mechanisms — TB-500 work centres on actin binding and cell migration, while BPC-157 work centres on angiogenesis-related and gastrointestinal signalling pathways.

A batch report, where published, states purity as a percentage of total peak area from reverse-phase HPLC, alongside a mass-spec identity result confirming the molecular mass of the fragment — purity alone tells you the vial is one thing consistently, only mass spec tells you it is the right thing.

A legitimate batch report names the compound, states the lot number, dates the analysis, shows the chromatogram rather than only a summary figure, and is signed by the testing party. A single-line PDF claiming '99% purity' with no lot, no date and no trace is a marketing document, not an analytical one.

Ask any Australian supplier for the chromatogram, not the claim. If a lot number cannot be matched to a dated report, treat any purity figure as unverified regardless of what the label says.

Before ordering: run the lot number you are quoted through our verify page and, where a report has been published for that exact lot, read it. Check the compound name, the analysis date and that the purity figure on the report matches the figure on the listing.

TB-500 is listed as 5mg and 10mg vials; each product page shows current availability and the price including GST.

Orders are sent by tracked Australia Post express. Rates and the free-shipping threshold are on the shipping policy page; delivery times are carrier estimates, not guarantees.

Aussie Peptides does not publish product- or lot-specific preparation, storage or stability data. Base preparation, storage and disposal on the supplier safety data sheet (SDS) and your institution's standard operating procedures.

Where a vial label shows a lot number and a batch report has been published for that lot, it can be looked up on the verify page and recorded alongside your experimental data.

Materials on this site are supplied strictly for in-vitro laboratory research. They are not offered for human or veterinary use. A research-use label does not by itself determine regulatory status; see the compliance page for official TGA guidance.

Purchasers must be 18 or over and are responsible for handling, storing and disposing of research materials in line with their institution's requirements and applicable Australian law.

Nothing on this page is medical advice, a dosing protocol, or a claim of therapeutic benefit. It summarises what the published research literature investigates.
