I’ve been taking this supplement for a week now. Started to notice the change in energy on about the 3rd day. The sweat affect it gives you is nothing BUT AMAZING!!! I’m still taking 1 pill a day so I can just imagine how 2 will improve my workouts and help me reach my overall goals. This I can say is a supplement that was WORTHY OF MY TIME AND MONEY! I take it in the morning with my breakfast and it’s still in my system once I use my pre-workout.I’ve noticed a uptick in my muscle mass abs strength to! All I can say is THIS IS THE REAL DEAL!!
