QUALITY CONTROL

How every lot earns its place in the catalog

Browse the COA Library
01 Sourced and quarantined Incoming lots from qualified manufacturers are held out of inventory. Nothing is listed, sold, or shipped until testing clears it.
02 Independently tested A third-party US laboratory runs HPLC analysis on the lot. Below the 99.0% purity floor, the lot is rejected. No exceptions, no house lab.
03 Documented on a COA Results are recorded on a Certificate of Analysis tied to the lot number on your vial, so your lab can verify before and after purchase.

Know exactly what you are buying

Plain-language guides for laboratory buyers. No hype, no health claims, just the quality-control literacy this field should expect.
GUIDE How to read a Certificate of Analysis What the purity figure, identity check, and mass balance on a COA actually tell you, and the red flags of a faked one. Read the guide → GUIDE Third-party testing: who verifies your vial How independent labs work, what chain of custody means, and why a vendor’s in-house numbers are not verification. Read the guide → GUIDE HPLC vs mass spectrometry What each instrument measures on a COA, what each cannot tell you, and why purity and identity are separate questions. Read the guide →
