Overview:
This is a liquid supplement intended primarily for what I believe would be facilitating/enhancing muscle pumps during workouts, much like its legacy supplement, Nitrox II, which I assume this product was intended replace, but I haven’t been able to validate that assumption.

Taste:
It tasted like grape cough syrup, which is pretty gross to me, but I don’t care so much about taste; I just gulped it down. You get used to it after a few doses.

Dosing:
I followed protocol and took ~2 tbsp about 5-10 min before working out. Since this is a liquid supplement, the dosing is never exact, thus you don’t necessarily get the maximum serving count possible (which devalues the product), especially if you’re a bit clumsy like me and spill some of it while trying to pour it into your table spoon. I guess what I’m getting at here is that, frankly, this supplement is impractical to take. I’m not sure what the logic was behind making a liquid solution instead of just putting exact measured doses in a capsule.
Lastly, you are not required to take this everyday to see results, which would add to the value of the product, however, I saw no results, so there wasn’t much value to be added to (read on).

Effectiveness:
For me, this product was a complete and utter dud. It literally did nothing. I was expecting it to be at least as effective as Nitrox II was, however, this product was a total fail for me. No increased pumps or vascularity, no energy or increase in strength. I’m extremely disappointed.

Value:
In short: worthless. I would never buy this supplement again and highly recommend people stay away from it. You only got 16 oz, and at 2 tbsp per serving, that leaves you with about 16 servings, and that’s only if you don’t spill any of it while pouring it into your tbsp. I paid $21.95 for something that essentially only lasts ~16 workouts. Even if this product worked, that’s a poor value.

Availability:
Apparently, this product was recently discontinued from BB.com, and not surprisingly, since it doesn’t work. Hopefully SciFit goes back to making Nitrox II, which worked amazingly well. They should have never tried to “fix” something that wasn’t “broken.”

My first review!!!

I thought I would review this since I have been taking it now for my past 17 workouts, I was interested in this products after finding nitrox 2 being one of the most highly praised products on this website, but was sold out on bodybuilding.com so i went with nitrox infusion instead.

Taste: pretty bad kinda like cough syrup and very thick but if it works who cares right??

When to take it: I take it when I get to the gym then i start streaching for 3 or so minutes then I start my workout. so about 5 minutes before your weightlifting.

Effectiveness: after hearing about this magical supplement for so long I had to try it but by no means is it a miracle supplement but it is a great product that gives you a great pump every time.

Its about a dollar a serving from bodybuilding.com and isnt a great value but isnt that bad either(with s&h 21& for 16 servings)

Final Thoughts: The best thing i like about this product is it motivates you to lift harder to acheive a greater pump, I do recommend this product. I also have stacked it with c4 and jacked so ive never taken it by itself prior to a workout if that means anything. ohhh yeah and 1 ml is the cap size so fill the cap full then take it, I was confused at first theres no mention of it on the bottle or cap. It does increase sexual desire especially in the morning but nothing too crazy.

I just finished 2 bottles of this and I was pretty impressed when compared to other no2 products. I stumbled upon this when Nitrox 2 was out of stock. IMO I think I like this better than Nitrox 2. The biggest effect I noticed was that my libido went through the roof with Nitrox Infusion

This is the first pump product that I have tried and it really kind of happened by accident. What I wanted to use was Nitrox II but bb.com has been out of it and I had some money to spend. I did some reading on this on bb.com and on Sci Fit's site and decided with the deal that bb.com was offering I really wouldn't be out much if it didn't work for me.
Like many of Sci Fit products, this one works. It is a liquid form of Arginine Alpha-ketoglutarate with PH controlled delivery like many of their other products. There are 16 servings per bottle. So, if you were to only buy one bottle it works out to a little over a dollar a serving. In my case I got the 2 for 1 deal at bb.com so this was a great deal. One of things that I really like about this is the timing of when to take it. You take it right before you workout, 5 minutes or less before you start. I workout very early in the morning and this is perfect for me, I don't have to wait 30-45 minutes or whatever for it to kick in.
The flavor was grape and it kind of tasted like grape cough syrup and kind looked like it too. Not bad, not great either, but definitely more than tolerable. This stuff is amazing. I could feel it being absorbed in to my body. I know it sounds weird but that's how it feels.
The first time I took it I took it by itself without my PWO drink just to see how it went.
The pumps were awesome and I thought tomorrow I'm gonna stack this with my Jacked and see how that goes. It went beyond anything I could have hoped for. When stacked with Jacked or C4(I use both) the pumps are incredible. I feel full pump at the end of the first set and it doesn't matter what body part I'm working that day.
By the middle of my workout the pumps are so good that they "hurt". Not in a bad way mind you. Sometimes I even have to take a longer break than normal between sets just to be able to keep going. I have seen veins pop out in places that I never have before. I rarely if ever saw them in my legs and I do now.
Since I have not used a pump product before other than a PWO I have nothing to compare to i.e. Yoked, Nitrox II, Nitrix,etc... I am going to try Nitrox II sometime but for now I will ocntinue to go with this. I highly recommend this and especially for those that don't want to wait the time that you have to with other products to kick it. This was almost immediate. Great value right now on bb.com, 32 servings for $16.99. Give it a shot for the price you can't hardly go wrong.
