GLP-2 T - 30mg lot TIR30N022525 test results, explained
Every result printed on this certificate, as reported by Janoshik, with a plain-English note on what the test measures. "Pass" and "specification" wording comes from the certificate; where the lab prints no pass/fail, we say so.
| Test | Result on the certificate | What it measures | This lot |
|---|---|---|---|
| HPLC purity | 99.779% · Per vial: 99.779%; 99.830%; 99.799% (lowest, 99.779%, shown) | HPLC separates the sample into its components; purity is the share of the detected signal that sits in the main peak. On its own it doesn't show which molecule that peak is. That's what the identity test is for. | No pass/fail printed; reported value at or above 98% |
| Identity | Not reported | This certificate doesn't report an identity test, so it doesn't confirm which molecule is in the vial. Purity and quantity alone can't tell you that. | Not tested on this certificate |
