TB-500 research in the UK
TB-500 is widely studied as a synthetic fragment of Thymosin Beta-4, the actin-binding protein with one of the most extensive regenerative-medicine literatures of any small peptide. UK research groups working in tissue repair, angiogenesis and exercise physiology models rely on research-grade supply outside the prescription channel.
Peptx TB-500 is sourced from vetted manufacturers (independent ISO 17025 lab testing) and is HPLC and Mass Spectrometry tested at the manufacturer (documentation not shipped with orders). Independent ISO 17025 retesting is supported by a 14-day purity refund policy.
UK domestic dispatch means no customs forms, no import VAT and no border delays. Prices display in GBP, converted live from wholesale USD source pricing.

Independent purity verification
Peptx stock is backed by manufacturer HPLC and Mass Spectrometry data plus independent spot checks, at typically 99%+ purity (HPLC); the guaranteed minimum varies by compound. Our suppliers are not chosen on a single rating. We weigh independent testing at accredited ISO 17025 labs.
Independent laboratories test our material on a rolling programme: random quality-control checks, tests on stock we buy in, and testing as part of vetting every new supplier. Certificates are published openly in the COA Library rather than issued per order, so you can read the laboratory's report before ordering, not after. Independent verification is expanding across the catalogue, with further tests in progress across September and October. If you want your specific batch independently checked, send a sample to an accredited ISO 17025 lab (see our Recommended Labs at /testing): a result you commission yourself carries more weight than one handed to you by a seller. Any independent lab result below the product's stated guaranteed minimum purity, or a sealed-vial endotoxin or sterility failure, is refunded or re-shipped within 14 days.
All compounds are supplied as sterile lyophilised powder in sealed vials, packed with desiccant, and stored at controlled temperature throughout the supply chain.

TB-500 UK FAQ
Is TB-500 legal to buy in the UK for research?
TB-500 is not a controlled substance under the UK Misuse of Drugs Act 1971 and can legally be sold for in-vitro laboratory research. It is not licensed by the MHRA for human use. All products supplied by Peptx are strictly for in-vitro laboratory research and are NOT for human or animal consumption.
How does TB-500 relate to Thymosin Beta-4?
TB-500 is a synthetic peptide corresponding to the active actin-binding region of the larger Thymosin Beta-4 protein. The two are commonly conflated in popular sources but the literature distinguishes between full-length TB-4 and the TB-500 fragment.
How long does UK delivery take?
Most UK orders are dispatched within 24 to 48 hours of payment confirmation and delivered in 3 to 5 working days using tracked Royal Mail or DPD services.
What purity is Peptx TB-500?
All Peptx TB-500 is guaranteed at 99%+ purity by HPLC and Mass Spectrometry. A 14-day refund window applies if an independent ISO 17025 lab report shows purity below the advertised level.
What is the minimum order quantity?
Minimum order is 1 box of 10 vials. We supply primarily to research laboratories and group buys rather than individual consumers.
