We test every batch with independent third-party laboratories and provide a Certificate of Analysis (COA) with every order — confirming purity by HPLC and identity by mass spectrometry. Because batches rotate, we issue the exact current-batch COA at the time of purchase so your paperwork always matches the vial you receive.
Want a COA before you buy? Request the current report for any compound below and we'll send it over. Every order ships with its matching COA in the box and by email.
