running my first winny(injectable) cycle in about a month. Ive read 50mg ED is the dosage. Im stacking it with sust 250 and tren A. I train 5 days a week mon-fri weight training with 20min of cardio ED. Now do i inject even on the weeknds when i dont train? Or just on the days i train? I know the half life is very short in the body. Also when i pin should i rotate muscles? Ive heard winny is very painful on preceding days and the injection itself. And dont want to keep hitting the same muscle to create more pain for myself. If somebody that has experience with using winny could help me out that would be great, thanks.
