GLP-2 T - 10mg lot DR10N052526 test results, explained
Every result printed on this certificate, as reported by Accumark Labs, 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 | 99.96% · Double Regulator - Purity: 99.96% (spec > 98.0%; lab status: Conforms) | 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. | Meets the lab's specification (> 98.0%) |
| Identity | Conforms | 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) | 12.2 mg | How much peptide the lab measured in the vial, compared with the amount printed on the label. | 122% of the 10 mg label amount |
| Endotoxin | Conforms (Spec: ≤ 5.0 EU/mL) | 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) |
| Rapid sterility screen (PCR) | Conforms (Spec: Not Detected) | A DNA-based (PCR) screen for common microbial contamination. It is a rapid screen, not a full sterility test. Test as named on the certificate: Rapid Sterility Screening (PCR). | Pass (as reported by the lab) |
