I am going little blunt with it. Personally i am not a fan of fat burners. All fat burners work the same way using some garcinia, grape seed extract & caffeine. This one contains no caffeine. But, that’s not enough to stand out. For my body type caffeine is a boon, my pre workout is a black coffee since ages. Caffeine is a friend to my body. But, those who are caffeine intolerant, have issues with kidney, lower water levels in their body or dull skin must stay away from caffeine & coffee both.
About this product: Yes it’s effective. But, i would rate it 5.5 out of 10 in terms of productivity. Remember one thing, supplements will work like a wonder if your diet & workout is balanced.
