Hey guys I have seen everyone recommeding ON whey protien but I have used 2.04 kg ON whey protien of chocolate flavour and I am doing workout from last 5 months I started using it after 3 months and I finished this box few days back but I didnt see any much improvement instead I had to do two tests of Kidney function and Liver function .Everyone says if the product is sealed then it is original I bought the original product but still didnt find it effective on my body I think everyone should prefer natural diet like chicken fish eggs etc Thats my review on it.THANK YOU
