Gotcha, that makes sense. May I give some advice? Compete as a bodybuilder in a drug tested organization. I did so, 6 times. Make sure they give a polygraph, as it is much cheaper and IMO better at outing cheats. It was the ANPPC if I recall correct, and guys were drug free.
I am generally pro steroid, but I HATE it when guys run gear and then beat the piss test. You will also prep differently.
Drug free bodybuilding is great (IMO) unless you are one of those sanctimonious judgmental shits.
Were you natural when you made those lifts, because those are exceptional numbers if you were. They are still good numbers even if you were on.
Power-lifting will give you a good foundation to build upon, and higher reps will fill your muscles out.
