I usually goes to the gym about 430am and yes this is the best pre work out that does not have crush effect on me during the workout it maintain the energy level through out the workout and after. 1st time trying it definitely not the last time.
Have you had a long and tiring day? Have you felt that you could have done more?
Black energy imbues you with that awesomeness to allow you to work till you feel satisfied and have a sense of fulfillment at the end of the day. Even better, you will still have energy left to complete house chores and spend time with family.
Give it a go ladies and gentlemen!
