Does what its meant to !
Used it Extensively during the early phases of my 5 years of weightlifting. A great Aid to putting on that mass and size one expects while bulking up. Taste, Mixability, Effectiveness,; this Mass gainer is a winner in every sense. My favourite flavour being Vanilla. From price point too it is a value for money.

Been ordering this for a while now and it is seriously helping me bulk up. Tastes good and is easy to mix. Favourite of mine would be cookies and cream!
