I love getting all tingly from BA... take it daily now thanks for Mr. Cooper's rec.
I've taken NO-Xplod in the past and didn't like it. It had to be dosed just right to be effective. Too much and I got naseous, too little and I felt nothing. It also made me crash about 2/3 of the way in and I hated that. There is a NO-Xplod v2 now and I have some samples but haven't trie dit yet.
I've also tried Animal Pump. I'm pretty sure this is non-stim, but its 30 packs in a can and a lot of pills to swallow. But it did exactly what it said. Nice, smooth, clean energy all the way through, no crash, great pump.
Currently on Hemavol + Maximize v2 and I'm diggin' it. Feels different/better than what I've tried previously but I'm going through it pretty fast at about 2 scoops of each!
