Do you think that an athlete that has a total testosterone of 600 performs the same as one with one of 840? You are right that its not the sort of difference where you'll see gaining a pound of lean mass a week, but in natural bodybuilding, being able to add 10 or 20% more lean mass a year than otherwise is huge.
oh okay that makes more sense but were those studies done on normal healthy men that were not deficient in test?
