i never recomend weight gain powders to my members who want to gain weight and this is why:
1-it is so dence that people who don't have an apetite,once they have it get full and don't want to eat their regular meals.
2-this is the main reason,for the amount of calories that you are geting per serving,you are not geting enough protien,let me explain,lets asume that a serving of a certin product is about 800cal and the amount of protien is 60 grams,for me thats so much calories for 60 grams of protien,i'd rather my members go with whey protien 3scoops give you around 65grams of protien and only 350cal,also if some one needs to up the calorie content then they can eat some fruits or complex carbs with their serving of whey protien.
