1. I've used a few NO2 products, specifically 4EverFit's "AKG2", and "Detonator".
2. AKG2 is in the form of capsules. The compound that causes the diolation is called "arginine alpha-ketoglutarate". The capsules have no taste. You take 4 at a time, on empty stomach. They really, really lowered my blood pressure. Actually, too much. I became very vascular (which I am not by nature), and I was happy with that. I also noticed some increase in my pump, which was a bonus (although it was not nearly what the ad's claimed it would be). Basically though, I only purchased the NO2 product in order to increase my vascularity, and any thing else was a bonus to me. I experienced some problems with the AKG2 tablets, they made my chest feel, deep and breathing difficult for short momments. I also had trouble doing cardio while I was taking them, I always felt sluggish and starving, but my lifts went up a little bit. It is noteworthy that I have constantly monitored my blood pressure while taking these NO2 products, and I would highly recommend you doing the same. Case in point, on the AKG2 product, I noticed that my blood pressure began to get dangerously low about 1 hour after digestion, so I backed off from 4 capsules twice daily, to 2 capsules 4 times daily. This worked.
3. Detonator is a powder form, and it tastes like Yak p*ss. (it's really awful) It's a 3 to 1 ratio formula of Nitrous Malate to AAKG and Nitrous Malate to OAKG. So because there are different types of vasodilators, and this product puts together 3 of the best, so that if you do not react to one all that great, you get hit by the others. I have not experienced any of the unpleasant effects of the AKG2 product. The pumps have been slightly better. I have not found myself fatigued on Detonator. I have found myself slightly more hungry, but not as much as with the AKG2.
4. Something that may be of interest to some of you, I was forwarned that NO2 products can produce....ummm....increased blood flow to certain other area's of the body, and I can speak from first hand experience (no pun intended) that I've been getting 2 hour erections since I started taking the product. Not just once a day, but randomly as well as on call. The wife is liking it, so even if I decide to stop taking the NO2, I'll probably end up finding it mixed in with my food anyway.
