Epitalon Vial 10 mg lot EPIT10-005 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.

TestResult on the certificateWhat it measuresThis lot
HPLC purity99.77% · Per-vial HPLC purity: 99.77%, 99.78%, 99.75%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: EpitalonMass 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. Expected average molecular weight of Epitalon (PubChem): 390.35 g/mol. The observed mass appears in the certificate's chart and isn't transcribed here.Reported as matching the declared compound
Quantity (measured content)12.35 mg (mean) · per vial: 13.44 mg, 12.35 mg, 11.27 mgHow much peptide the lab measured in the vial, compared with the amount printed on the label.123% of the 10 mg label amount
AppearanceWhite Lyophilized PowderWhat 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)
Microbial screen (PCR)PassA DNA-based (PCR) screen for common microbial contamination. It is a rapid screen, not a full sterility test. Test as named on the certificate: Microbial DNA (PCR).Pass (as reported by the lab)
Elemental impurities (heavy metals)PassICP-MS measures toxic elements such as arsenic, cadmium, lead and mercury. Test as named on the certificate: Elemental impurities As/Cd/Pb/Hg (ICP-MS).Pass (as reported by the lab)
Fentanyl screenNo Fentanyl DetectedA screen for fentanyl contamination. Test as named on the certificate: Fentanyl screen.Pass (as reported by the lab)
