Suppliers listed here have been added to the Approved by PEPS101 programme. Read what that does and does not mean before using any of them.
What listing means — and what it doesn't
Where a supplier card says delivery, packaging or presentation has been checked, that means exactly what it says and no more. Peps101 does not analyse contents or purity, and cannot verify what is inside any vial. No regulator has assessed most of what these suppliers sell.
The one check worth doing every time: find the batch number on your vial, then verify that batch's certificate of analysis on the testing laboratory's own website. Not the supplier's copy of it. How to check a COA.

The calculator does arithmetic only — it assumes 100 units per mL, so one click is 0.01 mL, and its output is only as good as the numbers you put in. Several compounds listed are prescription-only medicines in the UK and many others are unlicensed, meaning no regulator has assessed them for human use.
