i only speak from 1st hand experience... none of the british lads i know ever do propper pcts, and that includes 2 pros and a british champ... they all have kids, dont need viagra etc etc...
i only started doin them from reading too much on things like this, they all rolled there eyes when i told them,,, now ive went back to not doin them and noticed no difference at all...
far too many internet experts making things much more complicated than they realy are, and sayin things like there set in stone......
and as far as the cant get hard on test... u could get to show level with no 'hardeners' at all, as much as people dont like to beleive it, it realy is down to diet and cardio..
