What Is HPLC Purity?
HPLC numbers sound impressive. They only matter when they belong to the batch in front of you.
Direct answer
HPLC purity is a lab-testing figure that indicates how much of the tested sample matches the expected compound under that testing method. For peptide buyers, the useful question is not just whether a page says 99 percent. It is whether the HPLC result is tied to the exact batch being sold, with a COA and batch ID visible before payment.
