How should these compounds be stored?
Our peptides are shipping in lyophilized form, which is stable at room temperature during transit. Once received, store unopened vials in a cool, dry place.
After reconstitution, store between 2-8°C (36-46°F), keep refrigerated, avoid repeated freeze-thaw cycles, and protect from direct light.
Are products stable during shipping?
Our peptides are shipped in lyophilized (freeze-dried) form, which ensures stability during transit. This powder form is highly stable at room temperature and resistant to temperature fluctuations that occur during shipping.
Research has shown no significant degradation or loss of purity when lyophilized peptides are exposed to room temperature during typical shipping timeframes. Each batch is verified for purity upon production, and our stability testing confirms maintenance of product integrity during standard shipping conditions.
For optimal long-term storage after receiving your order, we recommend storing the lyophilized peptides in a cool, dry place until reconstitution is needed.
