Every batch independently tested and verified. HPLC purity data, mass spectrometry, endotoxin, and sterility results, available on request for every product below.
Unlike suppliers who conduct in-house testing, every Peptide Labs batch is independently tested by an accredited third-party laboratory.
Every peptide is manufactured at our own Australian facility under GMP-compliant conditions. Chain-of-custody documentation runs unbroken from raw material through synthesis to our Australian Labs.
Each batch is sent to an accredited third-party laboratory, not tested in-house. HPLC purity results and mass spectrometry identity confirmation are published for every batch.
Every batch passes LAL endotoxin assay (<1.0 EU/mg) and sterility screening before dispatch. A single failed test means the entire batch is replaced.
All testing is conducted by an independent NATA-accredited laboratory with no commercial relationship to our sourcing chain. The COA you receive is issued directly by the lab.
Our testing partner holds National Association of Testing Authorities (NATA) accreditation for analytical chemistry, including reverse-phase HPLC and LC-MS/MS methods. NATA accreditation requires ongoing proficiency testing and audits.
The testing laboratory is entirely independent of our supply chain. They receive blinded samples with no commercial incentive to pass or fail. Results are issued directly to us and published without modification.
Reverse-phase HPLC (C18 column, UV detection at 214 nm) for purity quantification. LC-MS/MS for molecular identity confirmation. LAL chromogenic assay for endotoxin. USP <71> sterility testing for applicable products.
