The Cold-Chain Imperative
Peptides are thermally sensitive biomolecules that can undergo irreversible degradation when exposed to elevated temperatures. Even brief temperature excursions during transit — a package sitting on a loading dock in summer heat, for example — can compromise purity and biological activity. Cold-chain logistics refers to the end-to-end temperature-controlled supply chain that preserves product integrity from manufacturing facility to research laboratory.
Temperature-Dependent Degradation
Chemical degradation rates generally follow Arrhenius kinetics, meaning they approximately double for every 10°C increase in temperature. For peptides, this translates to significantly accelerated oxidation, deamidation, hydrolysis, and aggregation at elevated temperatures. A peptide that maintains 99% purity for months at -20°C might show measurable degradation within days at 37°C.
ROEHN Shipping Standards
At ROEHN, we employ insulated packaging with appropriate coolants for every shipment. Our protocols include:
- Insulated containers: Expanded polystyrene or polyurethane foam-lined boxes that maintain internal temperatures
- Gel packs: Pre-frozen gel packs positioned to surround the product and maintain 2-8°C during transit
- Expedited shipping: Priority shipping methods to minimize transit time
- Seasonal adjustments: Additional coolant during warm months; insulation optimization during cold months to prevent freezing of reconstituted products
Whether you are ordering Semaglutide, BPC-157, or TB-500, our cold-chain protocols ensure your research compounds arrive in optimal condition.
Best Practices Upon Delivery
When your order arrives, promptly transfer products to appropriate storage conditions. Lyophilized peptides should go directly to -20°C or colder. Document the condition of the packaging and any temperature indicators included in the shipment. If you suspect a temperature excursion occurred during transit, contact the supplier before using the products in your research.
