Excellent pre-workout, great energy boost before gym sessions
Outstanding pre-workout supplement! The C4 gives me consistent energy and focus for intense training sessions. I notice improved endurance and better muscle pump during workouts. The protein punch flavor is actually enjoyable - mixes smoothly without grit or sediment. Starts working within 15-20 minutes of consumption. The 210g size offers great value for the price. Highly recommend for anyone serious about their fitness routine. Will definitely repurchase!

Helps get the job done.
I actually just take half a scoop because i'm kind of sensitive to caffeine, but it's quite nice. I prefer the raspberry flavor, but to be honest, this was more. Cost effective It does help you work out, the taste is quite decent, there's not a bitter, weird aftertaste
