NOS X9 (Precision Engineered)

In developing NOS X9, Precision Engineered researchers went back to the lab to create the most hard hitting nitric oxide product we’ve ever released. NOS X9 combines the nitric oxide inducing properties of pure L-Arginine with L-Arginine-Ketoisocaproic Acid to stimulate blood flow during hard training. A powerful dose of Yohimbe is also included for its alpha-2 antagonistic properties - which help stimulate energy and metabolism while further supporting blood flow. Once you add NOS X9 to your training program, your workouts will never be the same!

Difficulty sleeping

First things first I bought this product from GNC when I opened the bottle some of the pills had exploded and some were cracked it looked like they had exploded from the inside out. I looked at the expiration date and I still have a couple of month. I wanted to try it so I separated the exploded pills from the cracked pills to the intact ones. I took the three pills as Directed but the tingling sensation was to much I couldn't concentrated on the work out because it felt like the hair on the back of my neck was standind on edge my hands were shaking and my eyes were burning also felt like my heart was beating faster than normal. I also tried taking a knapp but was unable to because of how I felt. I have tried NOS products before and never had a problem. I will try and return the bottle to GNC.

This is one of the best nos products I have tried. It dosn't give you barley any bad side effects, besides maybe a couple stretch marks (for me)I think you should give this a try I really like this product. It gives you a great pump and good Vascularity.

Skin tingling

If you buy this product, BE CAREFUL! Although the bottle says to take three pills, when I did this, within 30 minutes my neck, elbows, and knees were bright red. It was the most intese pump I've ever had, but next time I try these I'm starting off with one pill and going from there; I recommend that you do the same. I am, however, only 135 lbs., so this may have had something to do with the level of intensity which I experienced. If I had to compare this product to N.O. Xplode as far as the level of the pump experienced, if N.O. Xplode was a 4, this product is a 10.

This was another one of the supplements I picked up for cheap at my local GNC. It was on the clearance rack for 11.99. It's an arginine product, but it also has the KIC. I looked online, and there is good research that supports it as a good anti-muscle fatigue item. In my 30 days using the product, I thought that the pumps were great, and I did find that my workout sessions lasted longer than normal--I wasn't as tired. Muscletech makes a similar product, but I'm sure this is cheaper. The only problem that I could see with this is that the pills were pretty large--if you aren't used to them, you could choke on them. Overall, I would say this is a 8/10

Upset stomach

This is a nitric oxide product that i bought at Vitamin world after using other nitric oxide product drink mixes. It comes in pill form, which makes it easy to take. It's basically arginine and yohimbe. So as far as ingredients, it's pretty simple. The serving size is three pills to be taken before and after workouts, but after experiencing upset stomach from taking three pills after a workout i stopped with that. I get a warm, energetic sensation from these pills (from the arginine) and decent energy, even though there are no stimulents like caffeine. The price was only thirty dollars for a bottle of 180 pills and they are fairly large pills that can be hard to swallow. Overall though, they have been a decent alternative to NO Explode considering the price. If money is a serious issue, these could be worthwhile, but i wish i had spent the extra money and gotten a product with less side affects. For a store brand product though, it wasn't bad. I'd give it a 6/10.
