Weight Gainer Shakes?

I used to use this and loved it,
4 scoops whey protein, vanilla or unflavoured, get a good qulaity whey protein isolate.
1 cup real ice ream not frozen dessert
1/2 cup natural peanut butter
2 banana
1/4 cup honey
3-4cups of milk depending on how you like the consistancy
some ice if you like it slushy
I cant remember all the numbers perfectly, drink this over the day, not in one sitting,
I think in total around 100-120 grams protein, i think around 200grams or so carbs, and around 30 grams or so fat, with 4 cals per 1 gram protein and 1 gram carb and 9 cal for 1 gram fat, puts it around 1000+ cals.  Eat good clean food the rest of the day 5 meals or so, depending on starting weight and your goal.  Make a good pre workout and post workout meal too.  Can get pricey but it is not loaded with artificial sweetners and preservatives a lot of the mass gainers have, there is some real good qulaity food in there.
I am pretty sure you can look this recipe up on google, keywords, whey protein, ice cream, peanut butter shake
Good Luck

I used to have the same problem, and realized I wasn't eating as much as I thought I was. Add an extra pb&j + a glass of milk before you go to sleep. Even if feel it will be too much, act as if its the medicine that's helping you gain/ maintain weight. Also eat a bigger breakfast. Add in extra sides with your meals, you'll gain/ maintain the weight you want. IMO stay away from those types of shakes, just get your calories from real nutritionally dense foods and you'll be fine.
