Guys,
I'm not making this up.
The New England Journal of Medicine ran a groundbreaking study on supraphysiological doses of testosterone a few years ago (2001??). It was a double blind study (the best kind) in which subjects were given...
A- placebo, with no training
B- placebo, with weight training
C- 600mg/week testosterone suspension, with no training
D- 600mg/week testosterone suspension, plus weight training
...the training program was pretty sensible, three 45 minute workouts per week. I believe the diets were pretty much standardised too. I think it ran for 4, 6 or 8 weeks, can't quite remember... but anyway it was a relatively long term study with lots of subjects.
The average results: (from memory, might not be exact)
A- placebo, no training negligible muscle change, gained small bit of fat
B- placebo, weights gained 6 lbs musle, lost small bit of fat
C- 600mg test, no training gained 7 lbs of muscle, lost small bit of fat
D- 600mg/week test, weights gained nearly 14 lbs of muscle, lost fair bit of fat
However, since then further studies using similarly large doses of testosterone (large by medical community standards not so large by bodybuilding standards) have found that the exercise response is related to the amount of exercise. They tested guys training once, twice, three times, four times, five times, six times and seven times a week with each session lasting an hour.
The biggest muscle gains happened with testosterone using subjects training three times a week.
Twice and four times a week caused similar growth responses.
Once a week did better than five times a week, because five times a week caused practically no muscle growth despite how popular gym folklore would have it.
Six and seven times a week actually caused the subjects to LOSE MUSCLE.
For non-supplemented subjects the results were less spectacular in terms of muscle gained and surprisingly different with respect to frequency.
Twice a week worked best.
Once a week or three times a week was the next best.
Four times a week produced some noticeable muscle, but the gains tapered off.
Five times a week had practically no effect at first, and later on in the study lead to a loss of muscle.
Six times a week caused the guys to lose muscle from the start, and many of them got sick.
Seven times a week left very few subjects standing at the end of the study.
Different studies with different levels of workout intensity (the above study worked the guys to failure) showed different results but the general trend held across the board.
So it's best to train approximately 2 hours a week, or 3 hours a week if using steroids. For the average trainee who wouldn't be working out as hard or intensely as was forced on these subjects under laboratory conditions the data would seem to indicate 3 hours a week (4 hours for steroid users).
Other studies showed that very advanced, muscular, long-time trainers took LONGER to recover: ie they couldn't train as much without a drop off in response. Really, really hard training bodybuilders did best on about an hour a week of training (two 30 minute sessions), steroid users could generally train 50% more often and make the same gains from workout to workout.
Does that clear things up guys?
Scary to think non-training steroid users can gain more muscle than a hard training weightlifter just by sitting on the sofa, eh? [see groups B and C above]
