I wonder if he meant anabolic steroids or corticosteroids.
From a discussion that I had with Shorter, Hilton was using methandienone, an anabolic steroid.
AKA Dianabol. While an excellent steroid and probably the all-time favorite of most bodybuilders and strength athletes, dianabol does cause users to gain weight from water retention...Oral Turinabol is essentially dianabol modified to correct this problem. If a runner used dianabol for performance enhancement, he or she would want to come off the drug at least a week--and probably more--before the race to avoid carrying needless dead weight. Assuming a lack of drug testing, of course.
