Where to Buy TB-500 in the UK

Buying TB-500 in the UK

Buying TB-500 in the UK is complicated by naming. The fragment and full-length thymosin beta-4 are sold under overlapping product names at very different prices, so the sequence stated on the analysis is the only reliable way to know what you are ordering.

The suppliers below are ranked on whether they publish sequence-level documentation, alongside verification and moderated reviewer feedback. Price differences on this product are small once content per vial is normalised.

What to check before ordering

• • Certificate states the actual sequence, not just a product name
• • Content per vial after lyophilisation is disclosed
• • Supplier answers technical questions before you order
• • A batch-matched certificate of analysis (HPLC purity and mass-spec identity).
• • ID verification — we confirm the trading entity behind the website.
• • Independent reviewer feedback on dispatch speed and packaging.
• • Price per mg rather than price per vial.
