Convinced by a guy at the gym to try it and decided to gamble $150. Monitored T profile over 8 weeks and T profile didn't change one bit. Last two weeks of the trial, I doubled the amount of product recommended, and total T went from 438 to 437. My T levels have been between 420 and 440 over the past two years. The claims of Ruthless Supplements that RS Transderm can raise your T levels appear to fail the validity test in my expereince. Go ahead and spend $150 and then another couple hundred on lab tests and find out for yourself.
