About Global Pure Laboratory
We are an independent testing lab. We test peptides, supplements, nootropics and research chemicals for purity, identity, content and safety, using UPLC-MS, HPLC, LAL endotoxin, ICP-MS and GC-HS.
We do not make, source or sell the compounds we test, so the results are not tied to any product. We have been running since December 2021 and have issued more than 12,000 reports.
