Okay, I'm bacccck, as promised. After a day off, I returned to the gym to do back. I took Need's advice and decided to combine my two pre-workout supps. I took two full scoops of Jack3d (I usually take 3), and I took 2 caps of Amp02.
I started on the lat pull down machine, with a 105 x 20 to warm up. Then I upped the weight to 135x10, and after the second set, I thought there was something wrong with me because I thought the muscle in my forearms was going to rip through my fucking skin. I've never experienced a pump like that in my forearms. Veins were seeping out like crazy. I continued with 6 more sets going up to 165x5, and by the end, my back felt like it was going to explode. I switched to underhanded close-grip pull downs, and the pump was just tremendous.
I had so much fucking energy, I was literally taking 30-45 second rests in between sets and doing an entire set without loosing any strength or reps at the same weight. I can't say it was all the Amp, because when I took it by itself it really didn't do anything; however, taking both together was one of the most incredible feelings I've ever had at the gym. I'm going to continue with this combo for legs tomorrow, then chest the following day and report back. So far, so good!
