Mainly bought it to gain weight and increase daily calorie intake. Thought chocolate flavour will taste good.. But taste is not that great with water. Had to mix with banana for some sweetness. Able to notice some improvement in performance (very subjective at this point) Good that they have a less quantity variant for trail

I will comeback or edit this after 1 month and tell the actual review
