A blend has one whole-vial purity but many ways to go wrong. We verify each blend component by component — identity and net content for every peptide in the vial.
A single whole-vial purity number can read above 99% while one component is underdosed. That's why every blend here is broken down per component: identity (is each peptide present?) and net content (does each match the label?).
