Thermal Stability of Lyophilized Peptides

A frequent inquiry at Biotech Peptides concerns the requirement of "cold-shipping." Most research peptides, when properly lyophilized (freeze-dried) and vacuum-sealed, exhibit extreme thermal stability. Our compounds can safely withstand ambient temperatures for 2–4 weeks without significant degradation of the molecular sequence. We synchronize our shipping schedules to ensure that products do not sit in carrier warehouses over weekends or holidays.

Institutional Receipt & Storage

Upon arrival at your research facility, we recommend immediate visual inspection of the vacuum seals. For maximum shelf-life and reproducibility of data, compounds should be transferred to a dedicated laboratory freezer set to -20°C. Biotech Peptides assumes responsibility for the product until it is confirmed as "Delivered" by the carrier. Please ensure your receiving department is prepared for the arrival of sensitive biochemical materials.

International Shipping Disclaimer

For researchers outside the USA, Biotech Peptides complies with all export regulations. However, the buyer is responsible for all import duties, taxes, and local customs clearances. We provide accurate commercial invoices and HS codes to facilitate smooth transit through international borders.
