Crush Research publishes a public per-batch Certificate of Analysis library. Most certificates are from ILS Laboratories (San Diego, CA), and the library also holds certificates from Freedom Diagnostics and BTLabs. Each ILS report runs a Full QC Panel — peptide purity and identity by HPLC, net peptide content, endotoxin by USP <85>, heavy metals by ICP-MS (USP <233>), and sterility by PCR — and reports HPLC conformity across three samples per batch, the multi-vial testing Crush is built around; some lots also carry an immunoassay fentanyl screen. Every ILS report is signed by the ILS lab director and independently verifiable at portal.ils-lab.com with the access code printed on it. Crush states it is one of only a handful of vendors in the space to conduct multi-vial testing, with full sterility and heavy-metals testing being rolled out across the catalog. Retatrutide and Tirzepatide are listed on-site under the coded names Triple Agonist and Double Agonist respectively.
