Cyborg used steroids as we all know, and look at her, even without steroids she's annihilating all the competition primarily through brute force.
Is it possible she's continuing to reap the benefits of steroid use even though she's currently clean?
Absolutely according to a few studies... such as:

The researchers discovered that the lifters who had once taken the drugs had a comparable number of cell nuclei in their quadriceps as athletes who were currently performing high intensity training.
Research suggests that athletes who use steroids for a short period can benefit for their
entire careers.
