Supreme 90 Day system

Has anyone here tried this? I had always been tempted to get the p90x but it was just too much $$ and I came across this. It's 20.00 and you get 10 Cds. I just received this and have started the system and WOW. Let me say that I am 48 years old and an avid exerciser, I jog, bike, I do interval/circuits, have elliptical, free weights, weight machine and many exercise videos, work out 6 days a week for 60-90 minutes, and I am just not getting what I want. And I eat pretty good/healthy too. I guess it is due to me aging, hormones, hysterectomy-all that good stuff. Been knocking my head against the wall and so I decided to try this because what I was able to see online is that it is very similar to the p90x but way less $$ and all of the reviews were good. Only doing a few workouts will say that it is challenging (good) and I am feeling it so time will tell.
