Lyophilised (freeze-dried) peptides are most stable as a powder, kept cool and dark. General laboratory practice is storage at −20 °C for the longer term, protected from light and moisture. Storage conditions are physical-chemical in nature and say nothing about application.

Batch traceability means every product carries a unique batch number that points to one production run and its lab report. That lets you trace exactly which batch you received and which CoA belongs to it. RetaEU records the batch number on your order so the link survives after purchase.

HPLC (high-performance liquid chromatography) separates a sample's components and measures their relative amounts. Purity is expressed as a percentage of the total peak area. When a published report states a purity value, RetaEU shows that value. Some reports state only identity and amount.

A Certificate of Analysis records reported measurements, such as identity, amount and — if measured — purity. Published reports at RetaEU can be viewed by batch number. The original report determines which data is available.
