About Alphex.
UK-based. Independently verified. Documented. We do one thing: supply research-grade peptides that match what the COA says.
Built because the grey market wasn't good enough.
Most UK research peptide suppliers ship from grey-market labs overseas. Delivery takes weeks. Customs seizures are routine. Documentation, when supplied, often doesn't match the batch.
Alphex is different. We synthesise, verify, vacuum-seal and dispatch from UK domestic stock. Every batch is independently verified by reverse-phase HPLC at 99+% purity. The Certificate of Analysis for each batch is published in our COA library, with the issuing laboratory named so you can verify it yourself.
We're not the cheapest. We're the most documented.
The four rules Alphex won't compromise on.
Every batch independently verified at 99+% HPLC purity.
Not vendor-supplied. Not generic. Third-party RP-HPLC, fresh per batch, before the batch goes on the shelf.
A batch-matched COA, published before you buy.
Not a generic document. The actual laboratory report for your vial's batch, in the public COA library, searchable by the batch code on the label.
UK domestic stock only.
Synthesised, verified, sealed and dispatched from the UK. Your order does not cross a border. Customs is never the reason your work is delayed.
