The lot is the point

A lot is a batch: material made together and tested together. The lot number is the one thing on a box that ties the vials in your hands to a test someone actually ran, and ours is on the top of every box. We built the business around it: every batch is tested before it is released, every lot has its own certificate of analysis, and the certificate you get is the one for your lot.

Every line wears the same label: the range colour on the band, the line code, the strength set large, the pack, the release standard. Learn to read one and you can read the whole shelf. How to read a label.

Every batch is tested by reversed-phase HPLC and released at 98.0% purity or better, and its certificate of analysis is tied to the lot number on the top of the box. You can see what you are buying before you buy it, and check it again when it arrives. How we test.

Every line is priced per box, per vial and per milligram, so a small box and a large one compare at a glance. One box is enough for an order, and shipping is free on every order.

Everything here is sold for laboratory research use only, to buyers who handle it as research material. We do not give dosing or usage advice. The research use policy.
