Nope, taking large dosages of gear actually makes you very very tired generally. Take a look at some pros who are in all out off-season mode; they look very tired, move slowly and look very lethargic. Why do you think many of them nap all day long? Add in large dosages of GH and you need ephedrine just to get out of bed.
Dude, I speak from experiance, like I said, I was up to 1200mgs of test for a couple of weeks and it severly disrupted my sleep and sleep patterns not to mention sweating like a pig in the middle of the night. Excessive gear not only raises body temp, it also disrupts sleep.
I've seen pros all the time in the offseason and yeah, they do move slow, mainly because their 30-40lbs overweight, constantly shoving carbs down they're throat, ephedrine throught the day then the crash comes, trust me, they are not sleeping because of large doses of gear. And if I had to guess, they take something to sleep as well!
