so i ran it at 20mg.. did not get a 2 or 4 fold effect from running it at 5mg.. no loss of strength, actually makes cardio and weight training much easier..
ever press so much and hard that you become dizzy from lack of o2?? does not happen here, and recovery is much faster..
I run it optimally 5mg 2x a day on workout and non work out days..
what does it do sexually?? again, your hrt is slower and thus you will take longer and not be out of breath..
my wife runs it 5mg 1x day and she can get her hrt to 174 and still carry on a conversation.. now that's increased respiratory function proof right there..
