sets!

Is it just me or does anyone else only get sore the next day if they do ony upward of at least 8 sets of between 8 and 12 reps? I find I don't grow any with only 4 sets, I figure as many as I'm doing would be overtraining but, I'm only sore the next day if I really push my body really hard with that many sets.....
does anyone else have this problem?
I feel I can do much more, especially my chest, I have done up to 12 sets and spent up to an hour just on my chest, it feels really good.
I only work one body part a week, so I figured it would work.
I'm probably way over training, but I need that soreness the next day.
Even with heavier wieght, I need the hight sets for the soreness.
Anyones opinion is welcome.
By the way, I'm also on Anadrol, and sustanon.

try adding alot more weight to do the smaller sets. heres what i do, i start out with a set of 12, then a set of 8, then set of 6 then 4 then 2 then 1 and then one more set of 8, use alot of weight tho, itll burnout ur chest.... PS. dont do it with out a spot.
