COA Library

The PYXAX COA Library lets researchers match a published certificate to the exact compound, strength, and lot shown in its record. A “COA pending” status means the corresponding documentation has not yet been published and must not be treated as available evidence. Exact-lot matching matters because results belong only to the material identified on that certificate.

Our Testing Partners
Launch batches
Krause Analytical
Accredited US analytical laboratory. HPLC purity and LC-MS identity confirmation on our first production lots.
As production scales
Additional accredited laboratories
Further batches may be tested by other accredited independent laboratories. Whichever laboratory tests a batch is named on that batch’s Certificate of Analysis — we name the lab that did the work, not a lab we intend to use.
Every lab is independent. No vendor affiliation. Results are what they are.
What our current testing does not cover
Sterility of the final sealed vial would require 503B compounding infrastructure which PYXAX does not operate. Endotoxin and heavy-metals screening are not part of our current per-batch panel — we publish what we test, and nothing we don't.
Independent Verification

Every certificate in this library is lot-specific and names the laboratory that tested that batch, so a result can be taken up with the testing laboratory directly.

You do not need to contact PYXAX to check a batch result against its certificate.
