Sweet, absolutely love this stuff. Here is a review for those that have not tried it:
Taste: If you like what seems to be the patented Prima/Sci lemonade flavor, you will like this. Actually quite a good taste for a pre-workout supp (9/10)
Mixability: Not a real problem here, a little tends to sit on the bottom (I mixed 2 scoops with about 8oz of water), but after a little swirling half way through drinking, it all dissolved (9/10)
Strength: I really like this stuff for strength. Felt great at the gym, really cranked some serious weight (9/10)
Pump/Vascularity: I do not respond well to the typical NO/pump products, but actually got some descent pumps out of this around gym time. Muscles felt full and good to go. (9/10)
Endurance/Recovery: Well, it was good for anaerobic endurance, at the gym lifiting weights, I felt fairly invincible. As for anaerobic endurance, I felt like it had little or no positive or negative effects. (7/10)
Energy: I am sure it is mostly a caffeine and I am not a fan of pumping caffeine into pre workout supps, but regardless, shortly after taking the N20, I had a good wave of energy that persisted throughout the workout and did not create any form of crash (8/10)
Other: I do not like the fact that it is a proprietary blend, actually very frustrating to me and I wish Prima/Sci would rectify this. I understand the reasons for using a proprietary blend, but Prima/Sci is usually better about disclosure in formulas and I would like to know whether or not I should be adding additional bulk for certain ingredients
Overall: When it comes to lifting alone (anaerobic workouts), this is the best preworkout supp I have used.
