What Are Peptides
Peptides are short chains of amino acids — the natural building blocks of proteins. They occur throughout the body and play essential roles in cell signaling, tissue repair, immune support, and countless biological functions. Because peptides are smaller than proteins, they interact more directly with specific receptors, making them powerful tools for scientific research.
Over the past decade, peptides have gained significant attention for their wide-ranging research applications. Pura Lab provides premium research-grade peptides manufactured to meet the highest standards of purity, ensuring researchers have access to materials they can trust.
How To Use
Pura Lab products are supplied as lyophilized (freeze-dried) powder, which means they must be reconstituted before research use. To reconstitute, carefully add the recommended amount of bacteriostatic water to the vial. This converts the powder into a usable liquid form while maintaining stability. Always use sterile equipment and handle vials with care to prevent contamination.
Once reconstituted, store the vial refrigerated and use within 30 days. For best results, avoid leaving reconstituted peptides at room temperature for extended periods, and keep them tightly sealed when not in use.
Storage Instructions
All Pura Lab products are manufactured using lyophilization (freeze-drying), ensuring stability during shipping and storage. In the lyophilized state, peptides can be stored at room temperature for short periods (up to 3-4 weeks). For longer-term storage, refrigerate at 2-8°C, or freeze at -20°C for storage exceeding several months.
Once reconstituted with bacteriostatic water, peptides must be kept refrigerated at 4°C and used within 30 days. Always avoid repeated freeze-thaw cycles, keep vials away from direct light, and ensure proper sterile technique during handling.
Shipping
All Pura Lab orders are shipped in discrete, light-protective packaging from our Canadian facility. Orders are typically processed within 24-48 hours, and you will receive a tracking number as soon as your package is on its way.
Delivery times vary by location, but most Canadian orders arrive within 2-5 business days. Because our peptides are manufactured using lyophilization, they remain fully stable during shipping, so you can order with confidence knowing your products will arrive intact and ready for research use.
