I tried Jack3d today for the first time as I could not wait til Monday to start. I only took 1 1/4 scoop and I felt it within 30 mins. The workout was great, but my stomach felt awkward the whole time and I did not have much of an appetite after. If this is a common side effect let me know. I am worried about it affecting me being able to have a shake and meal after my work out as that is the most important time for me to have it. I am trying to bulk and obviously appetite is a big issue for me. Any help is appreciated.
