Every order from Classic Peptides ships with complete documentation. We take compliance seriously because researchers depend on it.
Every product ships with a full COA from our independent testing partner. The COA includes HPLC purity percentage, mass spectrometry identity confirmation, lot number, and testing date — not a summary, the actual laboratory document.
We require third-party testing for every supplier's own test results. Purity and identity are confirmed by a laboratory that has no commercial relationship with our synthesis partners — an independent check that protects our customers from conflicts of interest.
Peptides are sensitive to temperature. Our compounds are stored at −20°C under continuous monitoring from receipt through dispatch. Shipments include appropriate cold-chain packaging and handling instructions.
All products are sold exclusively for in vitro research and laboratory use. Every customer confirms qualified researcher status at checkout. Age verification (18+) is required. Products are clearly labeled "Not for human consumption."

Our Certificate of Analysis is the complete output document from our independent third-party testing laboratory. It includes: HPLC purity percentage, ESI-MS identity confirmation, lot number, compound name and CAS number, testing methodology, and testing date. It is not a summary — it is the actual laboratory document.
Any lot that tests below ≥98.0% purity is rejected and does not enter our inventory. It is never offered for sale. There are no exceptions and no alternative "standard grade" — our threshold is non-negotiable.
