They do, albeit in much lower dosages to avoid or at least reduce the androgenic effects (hair/genital growth, voice deepening) of testosterone. Usually steroids with a better anabolic/androgenic profile are taken in addition or instead of testosterone.

Of course, there's also a small subset of female bodybuilders that lean into steroids to an extent to essentially chemically transition and I wonder if many of these might just be trans without noticing or disclosing it. As an additional caveat, in some places it can also be significantly easier to live as a woman on a lot of steroids than a trans man.
