Whats goin on guys. I want to run an EC stack. I have Ephedrine Plus tablets. is 12.5 mg Ephedrine HCL and 200 mg guaifenesin. Now i was gonna buy 200 mg caffeine pills, but i was just reading the lable on my jug of Fast twitch by cyto sport, and it contains 200 mg caffeine every scoop. I was wondering if i could just take a scoop of fast twict with my eph. 1 scoop ft with 2 tablets of eph. What do you think, Thanks again.
