How a brand earns
a place here
- 01We stock, we don't synthesise91.40%
Every compound is made by the brand on the vial. Our job is deciding who gets listed here at all.
- 02No certificate, no listing98.90%
A brand publishes a lot-level certificate from an outside laboratory, or it does not appear on this site. That rule alone excludes most of the market.
- 03Independent release99.47%
We pull samples from our own stock, unannounced, and have them tested. If the number disagrees with the brand's, the lot comes off sale.
Work out the vial
size you need
Set the vial mass, how much diluent you plan to add and the quantity you want per draw. It gives you the concentration, the volume to pull and the graduation to stop at on an insulin syringe. Most people work this out on the back of an envelope and order the wrong size.
