I'm a 50 year old amateur powerlifter competing in a couple of drug tested natural federations. In addition to the 3 Lifts there is from time to time a strict curl contest. I also practice Kempo Karate and have been for decades. I am 5 foot 10, weigh 189 lbs at 15% bodyfat according to the Accumeasure device. On to my question: I recently had a blood panel done and came back at 312 testosterone level. I have been exploring the wide world of Test Boosters. I was told by a fellow natty lifter that DHEA and Pregnenolone are not tested for by the federations. He recommended Diesel Test Procycle which contains both ingredients. Does anyone know the potential side effects of these two ingredients? I'm also somewhat concerned about the Yohimbe as I take a hypertension med (Losartan).
