As I have used this many times and I have not got any good result from this product. This product is only good for those people who is under 18 as this protinex does not contain high protien. It does not contain high protien only it contains less protien. If you want high protien weight gainer then dont buy this one. This product is good for childrens to increase their protien level. I will suggest that if you want less protien and to increase protien level for your children then this product is some what good for them. If you are doing exercise or gym then this not good for growing fast your muscle. Better than this product a whey protien is good for building up your muscles instantly and getting you strong. This product is just making you fool and achieving a high profit and I am suggesting you to do not buy this product at all. And also per serving ( 30gm) it contains around 6-8gm of protien which is very less for specially muscle builders and for those people who need a high amount of protien. Better than this product you can use meat, eggs, peanuts and other item which contain high protien better than this product. If you want a high protien then you should prefer meat to eat and gain a high protien if you are non-veg then you can prefer eggs and peanuts. So be careful and alert before buying this product thanks.
