For me personally, the use is medicinal, okay not totally, but as a gastricbypass patient, 3 yrs ago, I use it to help me build muscle mass, and maintain overall good health, as I don't and can't eat as much as most people who pursue a bb lifestyle, I only absorb roughly 70% of the nutrients I take in, and to date, I still struggle to take in about 2500 calories a day, as much as some of you guys take in a meal, I eat clean as hell, lots of protein..but alas, without it, I still continue to drop weight...one of the side effects. And if your wondering, I was 6'3 430lb at time of surgery, probably a bf of around 60, pretty sick huh..and yes it was my fault...I'm now 6'3, 235, roughly 15%, but maintain a well built, athletic appearance, through constant workouts and suppliments.
