Well after just finishing 1 full tub and some samples I used of this stuff back in the day, it's time to review this stuff.

Content:

German American Technologies pulls a BPI on this, meaning they list every freaking ingredient as their chemical name.

2-Amino-5-(carbamoylamino)pentanoic acid, more commonly known as the amino acid L-Citrulline.

(S)-2-Amino-5- guanidinopentanoic acid is straight L-Arginine.

L-Arginine Alpha-ketoglutarate is a salt composed of Arginine and Alpha-ketoglutarate bonded together.

(E)- 5-(4-hydroxystyryl)benzene-1,3-diol is Reservatrol.

4-[(E)-2-(3,5-dimethoxyphenyl)ethenyl] phenol is Pterostilbene, which is chemically related to Reservatrol.

3-Aminopropanoic acid is Beta Alanine.

1,3,7-Trimethyl-1H-purine- 2,6(3H,7H)-dione is Caffeine.

2-(Dimethylamino) ethanol is DMAE.

2-acetylamino- 3-(4-hydroxyphenyl) -propanoic acid is Benzoic Acid.

2-Amino-4- (ethylcarbamoyl) butyric acid is Theanine.

Rauwolscine (Rauvolfia Canescens L. [Leaf And Root])


As you can clearly see, Nitraflex contains a lot of the typical elements of a preworkout. Typical N.O boosters such as Arginine, AAKG, and Citrulline. Antioxidant support from Reservatrol and Ptersostillbene. Several different benefits of Beta Alanine which according to the bottle there is 1500mg per scoop. All the energy and focus benefits from 1,3-dimethylamylamine, DMAE, 325mg of caffeine, and etc. The only extraordinary ingredient is the Calcium fructopyranose borate(CFB), which GAT is marketing as a natural test booster. Which unfortunately has no solid or good evidence backing that claim from the studies I read thus far. Nitraflex is also Creatine free.

Consistency:4/10
I'll start with the bad on this review. I've never had as much problems with consistency with any other pre-workout as I've had with this one. I first started taking this 15 mins prior to working out. Which started off great, then quickly I would feel the effects less and less. Pump being the first to go. I switched to 20 mins prior and the same thing happened. Then finally I jumped up to 30 mins and same thing again. I even had to make the jump to 1.5 scoops 30 mins prior which stayed fairly consistent for the most part until I finished the tub. The only problem being I was burning through a 30 serving tub even more quickly and consuming a lot of caffeine just to get more out of a product marketed as being extreme and providing “seething intensity!” I do have a fairly high stimulant tolerance but having to keep bouncing around with dosing time and eventually having to use 1.5 scoops with a product marketed as only needing one scoop I find pretty ridiculous considering everything else available now a days.

Overall Effectiveness:6/10
Pump:7/10
As I previously mentioned with consistency, pump was the first thing that went out the door. However, when I did get good pumps they were average, nothing spectacular to say the least. I never noticed any deeper muscle contractions or anything like that as well.
Energy/Endurance:9/10
This does contain a lot of caffeine and contains DMAE, Beta Alanine, and 1,3-dimethylamylamine so this product does pack a lot of punch when it comes to this aspect. It's not as strong as 3 scoops of the original Jack3d or 1 scoop of the original 1MR, but the energy did last me through my entire workouts and was consistent throughout the whole tub.
Test boosting:1/10
This product does contain a ingredient marketed as a test booster but I never really saw any increased aggression or any alpha male feeling. I did get ***ed off at some times but that was because idiots at my gym seem to think the 20lb dumbbells go where the 55lb ones do. The problem could be with my age but I noticed much more when it comes to this aspect when I used Lit-Up which contains DAA.


Overall Taste:N/A
I don't really care too much on how a product tastes as long as it works. Unfortunately taste was one of the only good thing I can say about this product. Both flavors taste particularly good for being a pre-workout and they do taste like apple and watermelon respectively. They do both however have a very strong “medical,” aftertaste.

Value:4/10
I paid around 30 dollars for one tub of this. Which is by no means all that bad considering there is 30 servings per tub. However, with all the problems I had with this product and the only strong points with this product don't make it stand out above other pre-workouts I've tried by no means. So I have to rate the value fairly low here.

Overall:5/10
Overall this product did not make my expectations. I just had too many problems overall and there aren't many good things I can say about it entirely. I view GAT as fairly good company but I view this product as an almost total let down. Even more considering GAT recommends to go out and pay good money for the non-stim Nitraflex tabs just to get more out of this product. Everybody responds to everything differently, but there are much better products out there for pretty much the same price, I say save your money.

I will apologize ahead of time since this is my first review of a product on here. I should mention that I am stacking this with the Nitraflex tablets, creatine and a daily protein shake (or two). I have taken many other PWO powders and I do think this is one of the best. None of the PWO drinks are magic powders in a can, at least for me, but they do give me the added boost I need for hard workouts. Now I do believe this PWO has way too much caffeine in it. 325mg per scoop! That's like 4 cups of coffee! Ridiculous. I take like half to 3/4 of a scoop and it still does me good. I do see increased vascularity since taking Nitraflex and I do feel that it has given me some strength gains. I can't measure exactly how much because I started this PWO at the same time I switched to a totally different workout routine. Taste is pretty crappy but a lot of PWO are, to me. Not a big deal to me. I will say another negative thing about this that might be a dealbreaker when it comes to me ever buying this again. I do feel that the Nitraflex has definitely had an effect on my hormones, an effect that I did not like. Within about a week after starting Nitraflex, I have been moody, aggressive and overly emotional. No other PWO has affected me in this way before. Maybe it was just too much stacking this with the tablets but I do not like the person I became while taking this product. Is that a testament to the fact that it is doing what it is supposed to do? Perhaps but I will probably still shy away from doing another round of this.

I realize that I'm not supposed to post a review unless I finish the whole container of something and that I will probably get some heat for posting this, but I feel like I've got to let people know.
This preworkout is AWFUL, I've tried lots of them, and this is easily the worst.
It is jacked up full of caffeine, which is expected, but 350 mg is a little much imo.
For whatever reason when I take this pwo I bust out in a pretty bad heat rash and it only goes away until a good ways into my workout.
The only reason I tried this stuff in the first place was because I wanted to try something new and the vitamin shoppe was out of what I was looking for.
I always feel like glorified poop after all of my workouts, which is terrible for someone like me who has to get to class after his workouts.
I can honestly say that because of this pwo I will be straying away from pwo's as a whole from now on.
The ONLY pro I found with this workout was the taste, and that is because I personally love green apple flavored things.
Others may not agree with me, so to each his own. Just had to throw in my 2 cents.

This stuff is not for beginners. It is very potent. Within the first week of trying it I noticed myself stronger and able to bang out more reps then with any other product that I have tried before. Taste is a little funky but if you can get past the taste then this is a great product. It is a little pricey I paid around $42.00 at vitamin shoppe. Its got explosive energy, great mental focus. No creatine. The energy lasts I noticed even 2 hours after my workout.
