It is the worst product I have ever tried, It contains steroid which is very harmful to body as well as brain.I have tested this product deeply and found a high amount of steroid in it.Its flovour is good but I am warning you beware of these such products in market.These supplement makers are playing with the future of youngsters.These products will make your body muscular but have a tremendous negative impact after some time.So if you want a mascular body then exercise for 1 hour daily and eat a healthy natural diet which has a good impact on body.Dont ever depend on these such products to make a muscular body.
