As of today, SARM ingredients are not regulated by any government body. This means quality can vary widely from supplier to supplier. As of the updated version of this book, we purchased SARMs from the top 10 SARM suppliers and had each sample tested. We used HPLC testing, which is the most accurate way to test for the presence of these types of compounds. We tested the top 10 because we couldn’t financially afford to test every SARMs company on the planet.

After testing multiple SARM companies, we found that only two passed our testing, affirming that they sold what they claimed on the bottle. These companies were Umbrella Labs and Research Chemicals.

By the time you read this book, SARM laws could have changed, thus changing the aspect of research use. We are just educating people on the best SARM suppliers available today.

Independent Researchers Tested 44 SARM Product Samples. 2017 investigation by the Journal of American Medical Association concludes that half of the SARM products on the market do not contain what is being claimed on the label:

“In this limited investigation involving chemical analyses of 44 products marketed as selective androgen receptor modulators and sold via the internet, most products contained unapproved drugs and substances. Only 52% contained Selective Androgen Receptor Modulators, and many were inaccurately labeled.”[9]
