Certificate Of Analysis Database

All Virtus Peptides products are independently tested by ILS Laboratories, an ISO/IEC 17025-accredited analytical testing laboratory in San Diego, California. Earlier batches were tested by Motzz Laboratory; each Certificate of Analysis names the laboratory that issued it.

Every Virtus Peptides batch passes the full QC panel at ILS Laboratories: identity and purity (HPLC + LC-MS), net peptide weight, heavy metals (ICP-MS), bacterial endotoxin (LAL), and a rapid sterility screen. Purity and net peptide weight are averaged across three vials per batch to confirm conformity, and a batch only ships once it passes.

ISO/IEC 17025:2017 is the international standard for the competence of testing and calibration laboratories. A laboratory holding this accreditation has demonstrated, through independent third-party assessment, that it operates a quality management system, uses validated test methods, maintains traceable measurement standards, and produces technically valid results.

Yes. Every ILS Laboratories Certificate of Analysis is QR-verified. Scan the code or follow the link on the COA to authenticate it directly with the laboratory. ILS Laboratories is ISO/IEC 17025 accredited.

Each COA includes the compound name, batch number, test date, testing methods used, percent purity result, weight verification, heavy metals panel results, endotoxin screening results, and sterility screening results.
