so here's the deal. i looked for the best weight gainer for a while (one w/ a good calerie/protein ratio) good blend of protein, not too much added sugar) I came down to 2 ideal proteins.
-EAS Mass Factor Dietary Supplement, Chocolate
I also mix peanut butter, flax seed oil, and oats in every shake. tastes great, and is an ideal amount of caleries, and protein. Hope this helped.
