Testing: Labs & Certificates of Analysis
Crush publishes a per-batch certificate library on its testing page, with certificates from ILS Laboratories, Freedom Diagnostics and BTLabs. The ILS report Prof. Peptide matched is a Full QC Panel: purity by HPLC, net peptide content, identity, sterility by PCR, endotoxin under USP <85> and heavy metals by ICP-MS, with an access code for the laboratory's own lookup. Crush states that it runs multi-vial testing with at minimum endotoxin testing on every batch.
Prof. Peptide drew certificates at random from the testing page on October 11, 2026 and matched two at the laboratories' own records on October 14, 2026: KPV 10mg (99.784%) at Freedom Diagnostics and Double Agonist 20mg (99.39%) at ILS Laboratories, each naming Crush Research as the client. A BTLabs report in the same draw couldn't be checked at the laboratory's own records. The panel below lists every certificate's own results.
