We Test What Others Assume.

Most COAs stop at purity. Ours cover purity, heavy metals, microbial remnants and endotoxins on every single batch.

Tested before it's trusted

Every lot is tested by an independent, accredited lab before it goes up for sale. We publish the full COA: purity, heavy metals, quantity, endotoxins, method, test date, so you're never taking our word for it.

Trace every vial to its lot

Enter a lot number and see its production date, lab results, and COA, nothing sold without a matching record on file.

Built for the research bench

Standalone compounds and research stacks only, we stock the most popular compounds you want. The catalog is built for lab use, full stop.

No mystery supply chain

Every compound is sourced from a named, audited manufacturer, not a broker, not a reseller. Ask where it came from and we'll tell you.
