I personally use this product. Packaging Awesomee. Taste is also good in chocolate flavour and the new product is good in digesting. But its protein is not so good. I mean it doestnot give you the pure protein. it contains carbs in huge amount which helps you gain weight but its not that effective. if you want to gain some mass then use this as there is no side effects seen but if you are looking for a high quality protein then you can go for UN or ON.
I gained five kgs in two months which is good but you have to also maintain your diet otherwise you will not get the result and yes dont forget to workout. if you are not going to gym then dont use instead use a weight gainer. Hope my review helps u.
