I used this weight gainer twice. It has a flashy packaging and looks very promising. But its not effective at all. It creates a dependency on the product which is not good for you. The flavor is okay not too good. It’s better to take Whey protein if you are a gym person and looking for rapid weight gain. I just gained around 1kg and not much difference is noticed after 3 months usage. I would recommend you to take natural weight gainers like boiled fish , meat , raisins, nuts, eggs etc. It’s far better to have a slow but steady weight gain with the natural items rather than these overpriced products
