Batch-specific Certificates of Analysis (COAs) are provided by our vendors when available. Not all lot numbers have documentation on file. Requests are reviewed within 1–3 business days, and order verification may be required before a COA is released.

COAs are supplier-provided documents and reflect vendor-reported data. 406 Peptides LLC does not independently verify COA results. All products are for laboratory research use only. Not for human or veterinary use.
