Kens books the lion den tell about his aas usuage but not specific compounds. Id have to say tito, randy, frank are natural. they probably walk about at 230 not during prefight time. And weighing 205 isnt alot for someone 6 feet tall. PLus tito claimed to either max or workout I cant remember at 315. I saw randy doing bent over barbel rows with 225 nothing impressive. So Id say its superb conditioning. Also I say the training video for tito v randy and I think tito was only squating 405. YOu have to think about all the cardio these guys do including road work/jimp rope, then all there mma training(sparring,bjj) is all hardcore cardio. Prime example I was 185-195 my sophmore year of college dont know the bf, but after 12 weeks of pledging getting the piss hazed out of me and working out 4 days a week weights only I was 205 at 8% bf. Natural and this was binge drinking, eating garbage, puking several times a day ect. You dont need juice to be in good shape at minimal weight.
