Assay results
Every line the release panel ran for this lot, with the method, the acceptance criterion and the measured value — not a pass mark alone.

| Amino acid analysis | Net peptide content | ≥ 80.0 % | 91.2 % | Pass |
| Karl Fischer | Water content | ≤ 8.0 % | 4.96 % | Pass |
| Ion chromatography | Residual TFA | ≤ 1.0 % | 0.17 % | Pass |
| LAL kinetic chromogenic | Bacterial endotoxin | < 5.0 EU/mg | < 0.36 EU/mg | Pass |

Handling for this lot
- Appearance
- White lyophilised powder
- Storage
- -20 °C lyophilised. Reconstituted material degrades faster than modified analogues — use promptly.
- Reconstitution
- Use within 7 days of reconstitution at 2–8 °C. This is the least stable peptide in the growth category and the label reflects that honestly.
