i would just like to give my input about the product...first off, I dont buy into ANY hype of ANY product. I never give a product more credit than it deserves and im actually very critical when it comes to how well supps work. With that said, i tried a sample packet of this stuff, not expecting any more than just another preworkout supp to give a little boost. About 10 min after i took it my face and arms started tingling, then when i looked in the mirror i noticed i was turning red and felt my body temp rising. Ive taken all the other preworkout supps out their, never have i experienced this. At this point i almost went into a panic to call poison control or something bc i didnt know what the hell was going on. About a half hour later, the tingling subsided and i went to the gym. I felt like a madd man at this point and i was actually afraid of what i might say or do once i got to the gym. Mind you, i took this on an empty stomach first thing in the morning. I cant stress enough how insanely focused and intense i was in the gym. I dont post very much, and spend most my time researching, but i really felt the need to share this experience. Again, i am very critical about supplements and it is very rare that i am completly satisfied with a supplement, but this stuff is almost too much lol. oh and i am in no way affiliated with ntbm and ive never even talked to needto or any of the staff members before.
