I am a huge MHP user & dark rage was my preworkout of choice wth all the great perks of a preworkout. Pumps,focus,intensity,euphoria,strength,size & the list goes on. Huge thumbs up to dark rage & MHP. Yes I am MHP strong! I was reading reviews about jack3d & found it to be another placebo type product or hype. I read reviews on it & I decided wth the price I should give it a shot & believe me it is hard to take me away from MHP cause all products produce results for me. Anyways, jack3d I bought a tub & went right to 3 scoops & tht workout was very intense & the feelin was like nothin I ever felt & loved tht feelin & strength I was having. It wowed me 4sure. The next day I culdnt wait to use it again in the gym cause tht is the feelin I want in every workout but the nxt time I took it I didn't get the same effects wich was a down side 2 it. The workout was stll intense & its worth the price but I wish I culd get the same feelin as the first 3 scoops cause I loved it. Overall pumps & such r stll great & overall I give this product a close 9 of preworkouts I tried. Dark rage stll stands to be the best for me but jack3d is a close 2nd. One thng I dnt like is the type of creatine used in there formula. I wll admit, there is no product like tht on the market so good job usplabs...
