Remember his feeler sets?
I am a powerlifter and weightlifter, but recall a period of time where our gym was attracting more bodybuilders. And these guys did have the bigger "bodybuilding look" because of the drugs and the training style.
Anyway, one of the new guys told me he would take me through a leg workout. My usual squats at that time would warm up to around 160kg, ass to grass, and then do 5 sets of 5 reps at this weight, and 1-3 reps at a higher weight if peaking for a competition. So, he told me to follow his instructions.
From memory something like 140K max reps (I think i did maybe 20), strip off 1 plate each side, 100K max reps (maybe I did 20 again?), then something like max on 80kg, 60kg, bar. Man were my legs pumped after that, and aching with lactic acid for a few days. I think if done right, and with drugs, you could get massive growth doing this occasionally.
