you can literally gain muscle taking steroids without working out:
https://www.nejm.org/doi/full/10.1056/NEJM199607043350101
in that study, testosterone users (that didnt lift) gained more strength and size than those that didnt take testosterone+ lifted
taking steroids cuts years off the time it would take to reach your desired strength/size goals
yet somehow steroids makes lifting more difficult
MUSCLE STRENGTH
Muscle strength in the bench-press and the squatting exercises did not change significantly over the 10-week period in the group assigned to placebo with no exercise. The men in the testosterone-alone and placebo-plus-exercise groups had significant increases in the one-repetition maximal weights lifted in the squatting exercises, averaging 19 percent and 21 percent, respectively (
Table 4 and
Figure 1). Similarly, mean bench-press strength increased in these two groups by 10 percent and 11 percent, respectively.
In the testosterone-plus-exercise group, the increase in muscle strength in the squatting exercise (38 percent) was greater than that in any other group, as was the increase in bench-press strength (22 percent).
How could you possibly be surprised that people that aren't taking supplements or working out aren't experiencing weight gain or loss over a 10 week period?
This study is saying doses of testosterone. There is a difference between testosterone and anabolic steroid or corticosteroids. TRT (testosterone replacement therapy) isn't the same as taking anabolic steroids or corticosteroids and the results are not nearly the same. There are local places you can go to in any city and state and obtain TRT. The only reason governing agencies in some sports ban the practice of TRT is because it's difficult to distinguish between athletes simply using TRT or using anabolic steroids, corticosteroids and masking agents. Corticosteroids can be prescribed for a myriad of medical issues like asthma. You aren't using corticosteroids in a competitve fashion.
Now of you want to talk anabolics or cutting agents like ephedrine. We can talk. Not working out or eating proper on that shyt will kill you. You can't even take creatine and not workout or drink enough water without cramping up
