Will C4 cellucor extreme work for me?

[colorfully]

Hi all, i wanted to ask a simple question regarding c4 cellucor extreme.
I just started taking jack3d cause i wanted that extra "oomf" in my workouts, but it hasn't worked for me. First time, i took one scoop like recommended, then the second i took two, nothing happened, again. I'm about to up my dosage up to 3 and if that doesn't work i dont know whats gonna happen.
I dont know if i have a tolerance to caffeine or whatever, i don't drink much soda and coffee, but i do weight 207lbs. (dont know bf%)
but please bodybuilding, tell me whats wrong with me, i just want gains D:

also, on a sidenote, even if i dont feel the effects of jack3d, will i still see muscle gains from the ingredients? thanks

Time in the gym builds muscle not pre workouts[ they may do it indirectly by motivating you to GO to the gym and ENERGY to do stuff at the gym]

Jack3D isn't really a muscle building supplement. It's a workout aid to give you an energy boost while increasing concentration and focus.

Take some Creatine Monohydrate. Jack3D for me didn't really do too much, I did feel it but it wasn't as strong as other pre-workout supplements i've taken. It didn't live up to the hype for me. Try something else and see if that changes.
