I have been using this product for the past 2 months and there is not much difference in my body. in the last two months I have only been able to gain 1 kilograms using this product. I am very dissatisfied with this product and I wont be using this again, in the future. I bought chcocolate flavour and it is not effective at all. it is better for you to buy another supplemet with higher calories. muscle blaze has only 250 calories per serving.
