Karl has been drinking way too much Haterade... I have trained with Turk since he began his bodybuilding journey and know that he has never used juice (though he does look freakier than guys that do). He won his pro card as a natural in a tested show where they grab you right when you walk off stage and give you a piss test right there so how much more proof do you need?
There will always be haters like Mr. Karl, who's poor character and low self worth is extremely obvious in this thread, but I know that just motivates Turk even more.
At the end of the day it doesn't matter what anyone says on internet message boards, what matters is the hard work and dedication that Turk puts in 24/7 and the results speak for themselves.
Now i will wait for Karls response which will probably be extremely childish and immature and go something like "you are in love with Turk get off of his dick" which i can assure you i have never been on...
