Vilon Vial 20 mg lot VIL20-001 test results, explained
Every result printed on this certificate, as reported by Freedom Diagnostics, 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 | 99.13% · Per-vial HPLC purity: 99.15%, 99.14%, 99.11% | 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 (LC-MS) | Confirmed · compound named: Vilon | Mass spectrometry measures the molecular mass of what's in the vial and compares it with the declared compound. "Confirmed" means the lab found the expected compound. | Reported as matching the declared compound |
| Quantity (measured content) | per vial: 19.66 mg, 20.60 mg, 20.04 mg | How much peptide the lab measured in the vial, compared with the amount printed on the label. | Reported |
| Appearance | White Lyophilized Powder | What the lab recorded before testing: the colour and physical form of the material. | Recorded |
| Endotoxin (LAL assay (USP <85>)) | Pass (LAL, USP <85>) | Bacterial endotoxins are fragments of bacterial cell walls. The LAL assay measures them in endotoxin units (EU/mL); a pass means the result was under the lab's limit. | Pass (as reported by the lab) |
