Thought this was really interesting. A review of a study done over 10 weeks, 4 groups of men, same diet. 1 group was natural and didn't lift, 1 was on roids but didn't lift, 1 was natural and did lift, and finally 1 was on roids and lifting. The ones who trained done the same program. The results are quite interesting. http://www.aworkoutroutine.com/steroids-vs-natural/
Spoiler alert, here's the results for those who can't be bothered clicking the link,
Group 1 (no exercise, natural) experienced no significant changes. No surprise there.
Group 2 (no exercise, drug use) was able to build about 7 pounds of muscle. That’s not a typo. The group receiving testosterone injections and NOT working out at all gained 7 pounds of muscle.
Group 3 (exercise, natural) was able to build about 4 pounds of muscle.
Group 4 (exercise, drug use) was able to build about 13 pounds of muscle.
I've never looked into steroids very much. I'm a complete neutral on the topic in general. So i'm not sure if there's been studies like this done before or not but it's the first i've came across it.
What's especially interesting is the guys on roids and doing no training gained more muscle than the natural guys who trained. Proving, at least to an extent, that guys using steroids can make progress doing stupid programs (or, no program, as the case may be).
p.s I never scrutinised the study itself just read the review.
