I did the first stack for 6 weeks. I was eating 3,500-4,000 calories a day (my usual), and taking in 225-250 grams of protein a day. The second one I ran for 8 weeks, and the diet was the same, i never really change my diet unless i'm trying to lose bodyfat. Also if this was a sales account why wouldn't i post up web links to stores, and other businesses? I'm a personal trainer, the primary reason I have tried a lot of the pimped up supplements is to see what works and what doesn't work. That way I can better inform my clients. Plain and simple. Plenty of the stuff I have tried hasn't worked for me as well. I personally haven't gotten anything from CellMass or any of the Xyience products save for the NOX-CG3 which was pretty good.....though it did make me fart a lot lol.
