🔬 Our Independent Testing Standard
1. Third-Party HPLC
We reject supplier-generated marketing sheets. Only blind samples analyzed via High-Performance Liquid Chromatography (HPLC) by accredited independent laboratories are scored.
2. Quantitative Mass Spec
Mass Spectrometry (MS) confirms exact molecular weight and sequences, detecting heavy metal contamination, truncated sequences, or incorrect amino acid isomers.
3. Fill-Weight Audit
Vendors claiming 10mg must deliver at least 10.0mg of pure net peptide. Any supplier delivering under-filled vials is immediately downgraded in our directory.
