i think idealy it should be switched in and out with omega ultima. ultima is a non stim pre workout. ive used them for so long from superpump to 1rm to every other piece of crap out there it takes me alot. im a 4 scooper too.. cept last time i did it the blinds people finally showed up to fixed the windows or w/e they were doing. so i couldnt work out and i was just wacked, pacing around, having stupid conversations lol
