I think you guys are pretty much on the same page, in agreement that proper Steroid use + skill is enhancing, and Gear is a poor substitute for real skill and conditioning. The operative word here would be proper, in a nonethical sense.
The unfair advantage issue aside, the problem with gear in MMA, I believe, is that some of these fighters who I suspect use are doing so improperly, gaining mass for strength that makes less agile and the extra mass bad depletes stamina if done without additional compensatory cardio conditioning or else you gas from oxygen depletion and excess bodily heat. There's also the additional risk of connective tissue injury that's not developed in relation to the new muscle, it's overall better to put in on slower and surer to adjust to than suddenly and not.
I don't know what these guys are using, I would be using high dose Var and EPO with Rich Franklin's max endurance workout myself and a very strict planned diet,but I'm just a damn cheater, I guess. A smart cheater, though, better living through chemistry. :twisted:
