adolescent anabolic-steroid use stunts adult height via growth-plate closure

In plain terms: Can teenage anabolic-steroid use permanently stunt height?

Yes — androgens aromatize to estrogen, which prematurely fuses the growth plates; this is well-established endocrinology (high-dose testosterone is even used clinically to close plates in very tall teens), so steroid use before growth finishes can permanently limit height.

Disagree, or know a study we missed?

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
