SARMs Certificates of Analysis

As part of our continuous commitment to quality, we test every batch of our SARMs for sale for a minimum of 98% purity. Below are our most recent third-party COAs (certificates of analysis) for each product. Values between 100% and 101.9% indicate that our sample was purer than the reference standard it was measured against, since reference standards are also a minimum of 98% purity. We recommend that buyers of research chemicals always use a source that is third-party tested and call third-party labs to confirm that the results you see online are legitimate before purchasing products.
