"High" end indeed
But yes I know what you mean, though I don't know much about it either. Isn't it drugs that increase testosterone, like steroids, that can make people rage? :dunno: My impression is that SG is unstable enough without chemical enhancement.

the only thing I know of (ie witnessed ONCE so have seen how freaky it is) is 'roid rage' - which I gather was (in that case) synthetic (and illegally but apparently easily imported steroids)....very, very scary. cannot imagine personally why anyone would do that stuff but them I am SO not into exercise it isnt funny. but I believe those drugs do have psychiatric 'side effects' and add that to an already 'disordered' person - what a mess!! but of course this is all speculation on a boring Friday night!
