Every batch is third-party tested by Freedom Diagnostics, with published COAs where each sample ID links directly to its full lab report — so you can verify the exact lot you receive rather than a generic reference document. The certificates confirm identity by mass spectrometry and purity by HPLC-UV, and each is individually verifiable by its search code at FreedomDiagnosticsTesting.com. Purity runs 98–99%+ depending on the product. The catalog spans GLP/metabolic compounds (Retatrutide, Semaglutide, Tirzepatide, Cagrilintide, Mazdutide, Survodutide, Orforglipron), growth-hormone secretagogues (CJC-1295, Ipamorelin, Sermorelin, Tesamorelin, IGF-1 LR3), recovery peptides (BPC-157, TB-500, GHK-Cu, KPV, plus KLOW and GLOW blends), longevity and bioregulators (Epitalon and a deep Khavinson bioregulator line), and nootropics (Semax, Selank, Noopept).
