FAQs
Frequently Asked Questions
How do you verify the purity of your peptides?
Every production batch is analyzed using High-Performance Liquid Chromatography (HPLC) by an independent, accredited laboratory. We publish detailed Certificates of Analysis for each product so you can review the results before placing an order.
Where are your compounds manufactured?
All compounds are synthesized in FDA-registered, USA-based facilities that follow current Good Manufacturing Practice (cGMP) guidelines, using pharmaceutical-grade raw materials.
What exactly is a Certificate of Analysis?
A COA is a quality document generated after independent lab testing that confirms a product's identity, purity, and concentration. You can download COAs directly from each product page or request a copy with your shipment.
How should I store my peptides?
Lyophilized (freeze-dried) peptides should be kept in a cool, dry place away from direct light. After reconstitution, refrigerate between 2 and 8 degrees Celsius (36 to 46 degrees Fahrenheit) to maintain stability.
Will my peptides remain stable during transit?
Yes. We use insulated, temperature-resistant packaging for all shipments. In their freeze-dried form, peptides are stable at room temperature for several weeks, so they arrive in optimal condition.
