No, that is incorrect: https://www.nejm.org/doi/full/10.1056/NEJM199607043350101
A relevant quote from here (which examines the above study): https://www.strongerbyscience.com/the-science-of-steroids/
The group that took testosterone without exercise gained just as much, if not more, muscle mass than the people taking a placebo and actually working out.
Keep in mind, the dose for this study was 600mg/week of testosterone with nothing else added in. This wasn’t a several-grams-per-week pro bodybuilder steroid stack. This was a fairly low dose that might represent someone sticking their pinky toe into the world of steroids.
So for people who say, “oh, steroids don’t make you bigger and stronger. They just let you work harder,” I’m sad to inform you that such a statement is patently false. They may help with recovery and let you work harder, but I guarantee you that you could stick with the exact training routine you have now, start taking steroids, and gain more size and strength from it – no extra work required. And an untrained person might (would probably) gain more muscle from just taking steroids than they would if they actually worked out.
In any case, whatever your desired physique, even if it is the one without too much muscle mass but with very low fat, steroids will make it easier to get there.
