Been taking c4 for weeks now and noticed that when I would take i scoop it was ok, but taking 2 keeps me up and gives me real bad anxiety and jitters. No more of that. From now on I'll only take one scoop and only during daytime training.
Last night I trained late and took 2 scoops then a few hours at home trying to sleep and woke up with anxiety. Also just didn't fell right, real jittery. Did not like that. Finally got to sleep around 6 am and when I woke up I felt great when the stuff was finally out of my system.
C4 is the one supp I really did not like
It did nothing for me
