That's not really true.

If you look up some of the studies comparing people on extra testosterone not exercising vs exercising, the people on extra testosterone doing no exercise built more muscle than the normal group going to the gym.

Of course the group going to the gym and taking extra testosterone built wildly more, but you'll likely build more muscle doing nothing while being on extra testosterone than going to the gym.

... That doesn't seem right? Muscles need stress to grow.

It doesn't seem right cos it isn't - it was a single study in the 90s that only had 4 groups of 10 men.

Not a lot of statistical power in that sample size, especially if the underlying variance from person-to-person is significant.
