Purity you can verify
Trust in this field comes from documentation, not promises. Here is exactly how we identify, test, and label every batch — so you can check what you received rather than take our word for it.
Testing
Each production batch is tested for identity and purity. The results are recorded on a Certificate of Analysis (COA) tied to that batch's lot number.
Certificate of Analysis
Every order is accompanied by the COA for its batch. The COA reports the compound's identity and measured purity, giving your research a documented baseline.
Scan-to-verify labels
Each vial label prints its lot number (CW-YYYY-NNN) and a QR code. Scanning it opens the verification page for that batch, where you can request or view its COA.
Cold-chain handling
Peptides are packed and shipped cold-chain to protect stability in transit. Storage guidance (2–8 °C, protected from light) is printed on every label.
