Answers
Frequently Asked Questions
What are research peptides and how are they studied?
Research peptides are short amino-acid chains synthesised for in vitro laboratory investigation. They are handled by qualified professionals in controlled environments and are never intended for human or animal consumption.
How is purity verified, and where do I find the COA?
Every lot is analysed by an independent laboratory using HPLC and mass spectrometry. The Certificate of Analysis is published against the lot number before the batch is released for sale.
How should vials be stored and reconstituted for research?
Lyophilised vials are shipped sealed under inert gas and should be stored cold and away from light. Reconstitution protocols are documented per compound in the accompanying batch record.
How fast do orders ship, and how are they packaged?
Orders placed before 3 PM CT ship the same day. Everything travels cold-packed in discreet, unbranded outer packaging with lot-traceable documentation enclosed.
