Non-essential amino acid that buffers lactic acid in the body by increasing cellular carnitine levels leading to greater endurance, strength, and power.
A combination of arginine and alpha-ketoglutarate that boosts Nitric Oxide (NO) levels in the body while helping remove excess metabolic waste allowing you to workout longer and have better pumps.

Ingredients per 3 tabs:
Arginine AKG 750mg
Arginine HCl 250mg
L Ornithine HCl 250mg
L Citrulline Malate 150mg
Vanadyl Sulfate 15mg
So let's start off with the basics, where I will demonstrate my Wikipedia reading abilities. There are 1.6g of beta alanine, and that is definitely enough for it to be effective. Arginine AKG and HCl seem to be in decent amounts as well. Beta alanine increases blood flow and Arginine is the precursor to Nitric Oxide, so it's no surprise that these ingredients are present in good amounts here.
I don't know much about Ornithine and Citrulline other than they are fairly common preworkout ingredients. Finally, vanadyl sulfate is an interesting addition. Vanadium has been shown to mimic insulin, though it isn't a necessary dietary supplement. As far as this dosing goes, I believe if to be sufficient (though I personally don't think including it made any difference). There are vanadium tabs sold at GNC that only offer 1mg per pill so I'd say this is doing pretty well on dosage.
I give this an 8 on effectiveness because I absolutely got great pumps and it kicked in within 10 minutes, just like the bottle said it would. I love using this on shoulder days and seeing all dem striations across my delts, haha. The bottle also says you'll look vascular all day after taking this, but if you read closely on their website, Complete Nutrition recommends taking 4-8 tabs daily depending on weight. Well, no crap you're gonna look pumped all day if you keep devouring at that rate. I weigh 165 and the 3 tabs prior to workout is enough to sustain my pump.
As you all know, Complete Nutrition is mad expensive. Depending on where you are, this will cost between 50-70 bucks for 120 tablets, which is 40 servings. I bought them on a half-off sale and paid 35. It was an impulse buy, as I don't think you really need NO in your stack, but I'm pretty sure $35 for 40 servings is the limit at which I'll buy. That makes the price cheaper than Cellucor NO3 Chrome, and I like the supplement profile of this a bit more.
Yes, I would recommend this product if you can find it for half off like I did. Even though I think these nitric oxide boosters aren't essential, I think the profile with the beta-alanine makes it a great stim-free, creatine-free preworkout if needed. I have begun using it for that purpose, so I've really been able to stretch out the servings in the bottle. Also, if you want to check out your mad aesthetic bicep peaks in the mirror all day when you lift, NX6 will get you there. If mirin' yourself is what it takes to get you to the gym, then I guess these NO products work after all.
Chances are if you ever find yourself looking for this at Complete Nutrition, they will tell you how awesome stacking NX6 with Buzzerk (check my review of that, too), but that's just because NX6 compensates for Buzzerk's weak beta alanine content. The more you know already, the less the salespeople there will push things onto you. One visit I saw a guy getting suckered into buying $150 worth of crap, but I digress...
Sorry for the length! I tried to do my best to keep it organized and provide as much detail as I could!
