How to Store Lyophilized Peptides: EU Cold-Chain Guide

Lyophilized peptides are stable when stored correctly, but heat and repeated freeze-thaw cycles can degrade quality. Follow these steps after your WatsonPharmatech order arrives.

Before opening

Keep sealed vials at 2–8°C (refrigerator). Avoid direct sunlight and do not store in door compartments where temperature fluctuates.

After reconstitution

Use bacteriostatic water as indicated on your product label. Store reconstituted solution at 2–8°C and use within the period stated on the vial — typically 21–28 days.

Shipping in the EU

WatsonPharmatech Shop ships peptides with validated cold-chain packaging. Unpack immediately and refrigerate if the gel packs are warm.
