While I don't know much about Steve I would say that drugs are a lot more common in pro sports than people think. If someone's livelihood, not to mention their family's livelihood relies on them being in the best shape possible, you can bet there's a pretty decent chance they're using. Especially if the sport calls for extreme size. You are right though, if you train your whole life to be a big, thick linebacker you're essentially perma-bulking, and likely to have gotten pretty near your natural peak for lean mass meaning that you could cut down to a very desirable physique. But if said person cuts down, and leans out at like 240 lbs with 8% bodyfat, it's not just because they trained hard for so long, it's unnatural.
Data on MTX support the use of intramuscular MTX in Crohn disease, but such data are lacking in ulcerative colitis. The only trial of MTX in ulcerative colitis used a low-dose oral therapy [ 93 ] ; whether a higher-dose oral MTX or parenteral MTX (IM or SQ) may be effective in ulcerative colitis has not been studied. Several clinical trials showed that AZA continuation in patients with ulcerative colitis prevented relapse, as compared to those who discontinued the medication. However, other trials have shown trends but no statistically significant benefit of AZA in ulcerative colitis. [ 94 ]
