Does what they say it will do.
By Donald Flanagan
I am completely satisfied with this product. I am a 52 year old man that works out about an hour 3 days a week. my chest, abs, and arms look better than when i was in high school. I am a pharmacist and I recommend this product to anyone looking for a supplement to weight training. And it keeps getting cheaper.

Pretty Solid Product...but!
By reyrey1332
I have been on No2 Black for 3 weeks now. I have to warn you though, DO NOT START OFF TAKING THE MAX DOSE RIGHT OFF THE BAT!!!! I am 5'10 and weigh 165. The dosage on the bottle for my weight says to take 4 pills in the morning and 4 before lunch. The first day I followed the bottle. I immediately came down with the most splitting headache ever! It caused me to vomit, and I had chills and a fever. I was fine the next morning. I think it was just my body's reaction to that much arginine at once. So I decided to drop the dosage to 2/2 for a week, then 3/3, and now I am up to 4/4 in my 3rd week. I've never had a headache again.Ok, so how well does this stuff work? Well, you feel it immediately. Even on the low dosage I felt something weird in my muscles all day. You can feel the increased blood flow. I wouldn't say you have a full on "pump" the entire day...but you definately look more swollen and even more toned at times throughout the day. The pump you get during your workouts are unbelievable! This is what sold me. I've been working out my whole life, and I've never experienced the pumps in the gym like I do while on No2. It won't dramtically increase your strength or endurance, but it does a little. I have seen more gains than normal, but nothing crazy. I think it's more mental. You see yourself looking and feeling better so you push harder. Not sure if it's the No2 or just in your head...lolBut, I have to admit...I look better on this stuff. It may not have the same effect on everyone, but it makes me more cut and toned. Some people who mix it with creatine get more of the swollen and pumped look. I get more of the pump and cut look. (which I prefer)It's a good product...just be careful with the dosage when you start. I did research, and not everyone gets the headaches...but if you do, trust me they are bad! Worst headache you'll ever feel...good luck

Good, but I switched back to using Nitro Powerstorm
By James Exley
I got back into working out after not working out for almost 10 years. I?m 29 years old and I know that the right supplements can REALLY make your weightlifting more effective and enjoyable. NO2 black was something I tried after using Nitro Powerstorm for quite a while. I read good reviews for this though, and I was willing to switch if it did a significantly better job. So, I got NO2 black and started using it religiously. At first, I didn?t even notice that I had switched to something other than Nitro Powerstorm. It felt like I was using the same thing, and getting the same results. I had great stamina at the gym, I had a lot more pump, and I felt great. My strength and muscle size gains were consistently going up and I was stoked. But, I noticed after a little while that I was getting the runs after taking it. Mostly I noticed it while I was at the gym, and then for about 2 hours after taking my recovery protein shake. I wasn?t used that happening, so I backed up a little bit and realized it was probably this supplement, because I hadn?t changed anything else. Anyway, I switched back to Nitro Powerstorm and I was fine after that. I had great strength gains and a whole lot of stamina while working out, but I didn?t have to run to the bathroom every 15 minutes while taking it. So, I think that this product is good, and most likely not that many people will have the same problem as me while taking it. However, I?d like to avoid using it in the future.
