How to Read an HPLC Test Report
Every batch we release is sent for HPLC testing at an independent laboratory, and the reports are published on our Test Results page. If you have never read one, here is what to look at.
Label claim vs measured content
The single most important line: does the measured milligram content match what the label says? A result within a few percent of label claim is what you want to see. Well under claim means underdosed; well over means inconsistent manufacturing.
Purity
Purity is expressed as a percentage of the active compound relative to everything else detected. Higher is better; the remainder is related substances and process residues.
Why it matters
Dosing you cannot trust makes everything downstream — training, recovery, side-effect management — guesswork. A verifiable report is the difference.
