My reference for "jacked" would be more like a bodybuilder. Sprinters aren't really "jacked" more like lean and muscular.

Professional bodybuilders all use steroids. There are "natural" bodybuilders that don't use steroids or PEDs, and a few competitions for them, but the sport in general is saturated in drugs.

Compare sprinters with longer distance runners.
