So I purchased some on my last order with nutra since it's at such a great price. I started taking 2 caps before bed last week and I immediately noticed that I awoke MUCH more refreshed and my libido had improvided significantly. I'm also a little more relaxed on my diet and have noticed that I've not put on as much water and fat as I usually do with this kind of diet, ofcourse it's only been a week so we'll see about the fat burning effects. But for the sleep and libido effects, this stuff kicks serious ass!!! Although I do have a question, I notice that most of the cAMP bottles I've seen the ingredients listed with Cissus. My bottle didnt have the cissus but appeared to have mucuna pruriens instead. I want to order a few more bottles of this stuff, but I want to make sure I keep getting the cAMP with mucuna pruriens. If there was a switch of ingredients somewhere along the way and I missed it I apologize as I'm mostly a lurker. I anyone has any idea on this I'd greatly appreciate it. But just to re-iterate, you can feel this stuff work instantly for sleep and libido. 2 caps cAMP with 50mg zinc before bed makes pissing in the morning extremely difficult, lol!
