All research peptides (UK stock)

Alphex supplies research peptides to UK laboratories from domestic stock, with every batch independently verified before it is listed. This is the full catalogue: BPC-157, TB-500, GHK-Cu, Ipamorelin, GLP-3 (RT) and bacteriostatic water, in vial sizes chosen for bench work rather than bulk resale. In stock now: GHK-Cu in 50 mg and 100 mg vials, GLP-3 (RT), and bacteriostatic water for reconstitution. Every batch certificate is published in full in our COA library, so you can read the result before you order.

Every compound we sell passes the same three-stage pipeline before it is listed. Solid-phase synthesis to a defined target molecular weight, reverse-phase HPLC (RP-HPLC) at 220 nm against a reference standard with an acceptance threshold of 99+% purity, and a batch-matched Certificate of Analysis that carries the same batch number printed on the vial label. The chromatogram is on the COA, not just a headline number, and the issuing third-party laboratory is named. The certificate for each in-stock batch is published in the COA library before the batch is sold.

Stock is held in the UK and dispatched the same day for orders placed before 2pm Monday to Friday, by Royal Mail Tracked 24. There is no customs delay, no re-labelled import stock and no shared COA across compounds. If your own independent testing ever finds a batch below the purity stated on its certificate, we replace or refund it.

The catalogue is deliberately short. We add a compound only once we can hold a verified batch of it in UK stock, which is why you will not find fifty listings here. Each product page shows the available sizes, a specification table with sequence, molecular formula, molecular weight and CAS number, recommended storage and reconstitution conditions, and the research notes relevant to that compound. Vials are supplied as lyophilised powder under vacuum seal and should be stored at -20 C for long-term storage or 2-8 C short term, protected from light.

Prices are shown per vial, with the per-mg cost falling as vial size increases. Bacteriostatic water (0.9% benzyl alcohol) is listed alongside the peptides for laboratories that need a matched reconstitution diluent.

All products are supplied strictly for laboratory and in-vitro research by qualified researchers. They are not authorised for human or veterinary use, are not medicines, and are not sold for any personal use. By ordering you confirm that you are a researcher, that the materials are for laboratory research only, and that you accept responsibility for compliant use within your jurisdiction and institution.

If you are comparing UK research peptide suppliers, our research notes explain how to read a peptide COA, what 99+% HPLC purity actually tells you, and the twelve checks worth running before ordering from anyone, including us.
