I am 37 6'0 212lbs with 22% BMI. I am taking a stack of Deca and Primobolan 400mg/300mg weekly. I am shooting 2x per week Mon and Fri. Since I have been on this stack (8 weeks) I have gained 12lbs. I am happy with my results but I have noticed that I get winded very easily lately. Is it because I am heavier? Or is it due to the juice? I do run and do various aerobic workouts like P90X to keep my body fat low and to stay in shape. I used to be able to run 4 miles no problems now I have to stop. Just wondering what you guys think? This is my first experience with Primo
