Detailed Analysis
Purity & Testing
All opened COAs exceeded 99% by HPLC with a comprehensive ancillary panel (endotoxin, sterility, heavy metals, fentanyl). Primary gap is the absence of mass spectrometry for identity confirmation — identity relies on HPLC retention-time matching only. A separate Freedom Diagnostics report with LC-MS exists for one Retatrutide lot (Oct 15, 2026), suggesting MS may be added to the standard panel.
Product Selection
Focused catalog with notable depth in incretin-class compounds (Semaglutide, Tirzepatide, Retatrutide in 4 sizes). Also carries NAD+ 1000mg as a non-peptide research compound. No oral/capsule formulations.
