Yes, every batch is. Before a batch is approved for sale, a sample is sent to an independent, US-based analytical laboratory. Freedom Diagnostics serves as our primary independent lab.
What is tested
- Identity is confirmed by mass spectrometry (LC-MS).
- Purity is measured by high-performance liquid chromatography (HPLC-UV).
- Net peptide content is quantified so you know exactly what is in the vial.
New batches now run a full 7-test panel: those three tests plus bacterial endotoxin (LAL, in line with USP <85>), PCR microbial screening, ICP-MS heavy metals testing (arsenic, cadmium, lead, and mercury), and fentanyl screening.
Only batches that meet our purity threshold are released. Compounds are verified to 99% analytical purity, and the certificate of analysis (COA) for that exact lot is published in the COA Library so you can verify the results yourself. Compounds are synthesized in ISO 9001 certified facilities and fulfilled from our US facility.
