do you realy need to know,,, why make bodybuilding so complicated?... ronny and dorian were at the max size they could possibly acheive until the next new big drug discovery, theres a limit to how big u can get...
on the subject of receptor downgrade,,, it doesnt exist!.. i'll tell u why in everyday terms...
u take a 269lb bodybuilder, he's been on for 2 yr straight,, isnt grown like he used to ( see above ) , so he comes off to clean up.... looses size and conditon in the 6 month to a yr off.... comes back on, spends 6 month to get back to where he was, then is back to where he was before..
only thing that will change that body will be more drugs, different drugs ( slin etc ) even more time on etc etc... when youve already got to that stage where the extras are added and your still stalling,, your done, thats your peak size more or less,,, they think its downgrade cos there on 2000mg more than 2 yrs ago and there not gaining...bullshit....
