Questions & answers

Research & procurement FAQ

What purity level are your peptides, and how is it verified?+
Our catalog is held to a documented >99% purity standard. Every batch is analyzed by an independent lab using HPLC and mass spectrometry, and the results are published on the batch certificate of analysis.
What is a certificate of analysis, and how do I read it?+
A COA is the lab report for a specific batch. It states the compound identity, measured purity, the test methods used, and the date. The lot number on your vial matches the COA, so you can confirm the material in hand is the material on the report.
What is bacteriostatic water and why is it used?+
Bacteriostatic water is sterile water with a preservative, used to reconstitute lyophilized research material for laboratory handling.
How should material be stored before reconstitution?+
Lyophilized material is stable when kept cool and dry. Store as directed on the product page and COA for best consistency.
How fast do you ship?+
Orders are processed quickly and shipped with tracking. Shipping options and timing are shown at checkout.
Are these products for human use?+
No. All products are strictly for laboratory and research use only. They are not intended for human or veterinary use, diagnosis, or treatment.
