Built for Researchers.
You shouldn’t have to trust your supplier. So we made it impossible not to.
We test every batch because researchers shouldn’t have to.
The industry runs on “trust me.” We don’t. Codex is built on four non-negotiables — Test before we ship. Publish what we find. Verify every claim. And source only from suppliers we’ll name in public.
That’s the whole code — no fine print. If a batch fails, it never leaves the lab. If a result isn’t published, assume the test never happened. If a supplier won’t put their name on it, we won’t put it on our shelf.
How we back it up.
An outside lab, every time.
Every batch we receive is sent to an accredited third-party laboratory before it ever ships. Not self-reported. Not skipped on busy weeks. Every batch, every time — that’s the only number that means anything.
Six tests, not one.
Purity is a single line in a real Certificate of Analysis. We test for potency, identity, heavy metals, microbial contamination, residual solvents, and pesticide screening. A batch passes only when every panel passes.
Every COA, in the open.
The Certificate of Analysis for every batch we sell is published on our COAs page. You can match the batch number on your vial to the document on our site. No emailing for reports. No “trust us.” The receipt is public.
We don’t just claim 99%+.
We prove it.
Anyone can print a number on a label. We back ours with the actual lab report — every batch analyzed by HPLC and mass spec, every result published. The number on our site is a measurement, not a marketing line.
