Hi guys, I'm new around these parts, been lurking a bit, but need some help.

I have been around the gym for years on/off and have gone from as low as 155lbs to 223lbs depending on what I was trying. Right now I'm 190lbs, and am at the point that I would like to put some meat on my chest, but would like to cut/shredd. I was watching this infomercial (I know I know), but seemed to make sense, has anyone seen or used this P90X system? is it a bunch of BS? or does it actually work?? the testimonials look astonishing.
