Never said to avoid using ND.
No point in jumping on it if you keep on beating up your joints and tendons especially if you already have underlying tendon/joint issues.
Need to train smarter.
Far from common 100 mg/week of ND is going to throw on much muscle if we are talking about pure dry gains!
Would not even waste my time with such a dose if the goal was to throw on some size.
200 mg/week is where its true anabolic potential starts to shine.
