Who is using Jack3d and how is it working for you? I have been using it preworkout for about a month and to be honest I see no difference in energy levels. Im using one scoop 40 minutes prior to my workouts. What are your experiences with Jack3d? Should I go to 2 scoops?
If you are gonna go to 2+ scoops, I recomend that you try 1MR instead. About $40 per container, but has 2x the amount of caffeine and 1,3 dimethyl than jack3d. That's where the energy comes from......my 2c anyways.
i started with one scoop tried 1.5 scoops and settled with 2 scoops pre workout. It puts me in the zone and the pump is decent. I think it effects my post training appetite though...not sure but keeping an eye on it..
