Full QC panel
| Analyte | Specification | Result | Status |
|---|---|---|---|
| Peptide Purity (HPLC) | ≥ 95.0% | 99.62% | Pass |
| Identity (HPLC-RTM) | GHK-CU + BPC-157 + TB-4 Confirmed | Confirmed | Pass |
| Fentanyl Screen | Immunoassay, 50 ng/mL cutoff | Not Detected | Pass |
Sterility & endotoxin
| Test | Specification | Result | Status |
|---|---|---|---|
| Sterility (PCR) | No Growth | No Growth | Pass |
| Endotoxin (USP <85>) | Report Result | NMT 0.05 EU/mL | Reported |
Endotoxin is reported as a measured value rather than graded pass/fail: acceptable limits depend on route and matrix, and no universal threshold applies to research-use material. The laboratory reports the figure and leaves the judgement to you.
Elemental impurities
| Panel | Method | Result | Status |
|---|---|---|---|
| Arsenic, cadmium, chromium, lead, mercury | ICP-MS, USP <233> | 5 of 5 under limit | Pass |
Per-element measurements are on the signed certificate below and in the laboratory's own record.
