My favorite workout as of now has to be
APS Mesomorph.
Hands down the BEST Pre Workout Stimulant I have ever taken. Ive finished tubs of Jack3d, N.O. Xplode, Fast Twitch, Muscle Fuel, c4, and super Pump. None can Compare to the amounts of Energy and Focus that APS Mesomorph Gives you..
The only cons I can think of Is being overly Wired.. If you are caffeine sensitive, then I wouldn't recommend this product.. or at least start with half a scoop and work your way up.
I also recommend taking APS Mesomorph before your morning workouts early.. so you have the rest of the day to get it out of your system, making it easier to sleep at night..
