Quality assurance
Lab Testing & Certificates of Analysis
Independent verification on identity, purity and stability for every batch we release.
Our testing protocol
- HPLC purity analysis confirming ≥99% purity.
- Mass spectrometry to verify molecular identity and weight.
- Heavy metal screening on incoming raw materials.
- Sterility and endotoxin checks on finished lyophilized product.
- Stability testing across the stated shelf life.
Requesting a COA
A Certificate of Analysis is generated for every product batch. To request the COA for a specific lot, email the lot number printed on your vial to lab@clydespeptides.com and we will send the report the same business day.
Storage and handling
Lyophilized peptides are shipped at ambient temperature and remain stable in transit. On arrival, store vials at −20°C protected from light. Once reconstituted with bacteriostatic water, refrigerate at 2–8°C and use within the stability window for the compound under study.
