> Something like 4% of males admit to steroid use at some point. If you consider that non gym goers probably aren't using steroids (let's hope), that means a significant portion of fit males are.

"At some point" is not the same as long term or chronic use. From https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6517163/ :

> There is a distinction between lifetime ever-use of AASs and chronic use. Lifetime prevalence use includes a high percentage of short-term (even a single episode of) experimental use in teenagers and young men.
