MZ Biolabs is a mass spectrometry lab in Tucson, Arizona. Its COA page is unusually direct about the limits of purity testing, which is why we quote it in several explainers. This profile is not a rating.
What it says it offers
Certificates of analysis “for purity of raw powders and liquids as well as quantification of solutions, tablets, and capsules.” It says it frequently analyzes “peptides, SARMS, nootropics, vitamins, and other research compounds.”
The limitation it states
“Purity testing does not test for activity, sterility/endotoxins, heavy metals, or pH.”
This applies to purity reports in general, not only to this lab (endotoxin, HPLC).
Registration
The lab states it “is a US DEA Schedule III licensed facility.” Its home page lists a DEA registration number. We have not independently verified the registration with DEA.
