Eve never tried it but weight gainers are generally all the same with minor changes in ingredients. They do their job, but you want the bulk of your macros coming from whole foods, not weight gainers.
Also you can make your own weight gainer for less than half the price. More than 60% of weight gainers are simple sugars like dextrose. You can buy a sack of dextrose for like $10, add some protein powder and there is your weight gainer.
I will go into detail later when I make a thread about this.
