I am not really sure if it was working or not, as this is a supplement that you take to protect yourself, but as far as my heart and liver i was ok when using this in conjunction to prohormones..
So if thats how it works i quess it did the job and quite cheap compared to other sups.. And also practical as you only take 2 caps in the morning.
It's a powerful product and it really helps lessen mental fatigue. In fact the effect lasts at least 8 hours for me!I don't like pre-workout stuff with creatine because it upsets my intestines so this product is perfect for me. By the way, the taste is quite decent and it dissolves well in water.
