I have been using their Xpand (pills), NOV, Mega Milk, Mega Gainer, Dyma Burn, CLA, Creatine, Glutamine, ISO 100 protein powder and the Super Aminos. One thing that truely amazed me is the NOV and Xpand combo. My blood pressure is regularly high, 160/100. After taking these two products together, my blood pressure went down to 128/82. This was during a two month time frame. No change in diet and no change in my "supplement" usage. I went to my doctor to get my blood work done. That's when I found out that the L-Arginine in the NOV is what lowered my blood pressure. I am taken 4 Xpand in the AM, 4 NOV before and after my workout and 4 Xpand before bedtime. I really like thier products. Their worth a try.
