Weightlifting is already separated by class. As I understand it, weight alone is not enough to create a “fair” competition. A historical use of steroids changes your body composition so that you have more strength at the same weight, even if the use was years ago. From the article the implication is that the same is true for testosterone, giving male to female transitioned people a unfair advantage (as long as transition was post puberty).

Testosterone actually is one of the aforementioned steroids. The first sentence of the article at https://en.wikipedia.org/wiki/Testosterone (at the time of this comment) is
> Testosterone is the primary sex hormone and anabolic steroid in males.
