Recently I bought protinex and want to share my experience with you.
Flavour : Protinex comes in many flavours and the most selling flavour is chocolate flavour. I used chocolate flavour but when I put it in the milk it doesnt dissolve completely so I was having difficulty in drinking milk.
Packaging : Proteinx comes in a metal box which is good and strong too. The box has a strong grip on the mouth so even if it falls down it doesnt open.
So I will not recommend proteinx.
