Fentanyl: not tested. This report does not include a fentanyl screen.

Methods, as stated in the report

  • Identity confirmed by HPLC: chromatographic retention time comparison with a reference standard.
  • Elemental impurities analyzed by ICP-MS per USP <233> methodology. Acceptance criteria are internal laboratory quality screening limits for research-use materials.
  • Per-component content calculated from total net peptide content using the manufacturer's stated formulation ratio (GHK-Cu 62.65%, BPC-157 12.41%, TB-500 12.66%, KPV 12.28%). All components confirmed present by HPLC identity testing.
