I am in wk8 of using bayer primo at 400mgs/wk, Cyp at 150mgs/wk (watson) and Bayer/UA prove at 25mgs ed. Most would say this is too light of a dose, but my goal is simply to maintain muscle mass while I train for a triathlon.....and harden up and look good while minimizing side effects. I am very sensitive to sides and can't even hang with Tren at 200mgs/wk. Primo is my new favorite steroid, and I have tried them all. I am on a low cal diet and just shedding body fat. Muscle mass has been maintained and i've dropped around 8-10lbs of fat. The look to my muscles is very quality and many people are commenting. I am doing a shitload of cardio, sometimes my sessions last for 2hrs straight when running and biking back to back. Last wk I upped my testosterone to 200mgs/wk and my proviron to 50mgs ed in hopes of increasing my RBC count prior to the race. I have had ZERO side effects. BP is great, ZERO acne, no painful pumps while doing cardio. This stuff is just awesome. The only side I have had is a decrease in HDL which is caused by the proviron and was prior to starting the primo. I am very impressed. This is a quality drug with NO sides. The gains are not dramatic but very quality and noticeable. Can't wait to see what I look like come wk 16
