Product documentation
Know what you’re buying.
Start with the product page for ingredients, serving information, directions, and product-specific testing details. Testing coverage and available documentation vary by product and lot.

Every supplement we carry ships with a lot Certificate of Analysis and a facility certification letter on file with us. Those are supplier documents: we review them and summarize what each one covers in the table below, but we are not licensed to send copies to customers.
Questions about a specific product or lot, including anything the report on file does not cover, go to support@peakbiosupply.com. We will tell you what the documentation shows and what it does not.
A facility certificate describes the manufacturing facility; it is not a test result for your particular lot. Any testing claim should be read alongside the specific report and the tests it covers.
