Why Researchers Choose QSC for LGD-4033
The Janoshik COA is QSC’s primary differentiator. Janoshik Analytical is an independent Czech Republic testing laboratory that publishes results publicly. Every QSC batch is submitted externally — researchers can verify the COA is genuine and view results from the same independent lab. This is a higher standard than in-house QC.
QSC also stocks 99 compounds — the broadest research catalog available, covering peptides, SARMs, GLP-1 agonists, longevity compounds, oral steroids, and novel compounds like survodutide, mazdutide, and orforglipron that most competitors do not carry.
