Drugs allow you to do a lot of things which would be less than wise and useful if you were drug-free, for example training twice a day with a six-way split.
I confine my advice to drug-free trainees. Use the fullest possible range of motion, and go ahead and lock out your joints. If you lock out violently
then in the long-term you may get injuries, just ask Olympic weightlifters.
