Our Three-Stage Cold Chain Process
Arrival & Deep Freeze Storage
Fresh peptides arrive and are immediately transferred to a RIVACOLD walk-in freezer for long-term stability Commercial-grade walk-in unit Continuous temperature monitoring
Controlled Thawing Protocol
Upon order, peptides are gently transferred from deep-freeze storage to our temperature-controlled fridges using a slow thawing process, protecting their structure from thermal shock.
Pre-Dispatch Holding
Before shipment, peptides are kept at ideal temperatures in our professional glass-door fridges, ensuring they stay in controlled conditions until they are packed. For extra protection during transit, insulated shipping containers can be added at checkout.
