Gaining

I hope she knows your preference and it is you supporting her gaining... At first sight your search for products looks like secret feeding... I hope I'm wrong..

The best tasting weigh gain powder is Scandishake. It mixes great and packs a caloric punch.

When using weight gain powders to put on fat you'll want to stay away from protein based powders. So basically anything with the word "Whey" in the product name.

Instead you'll want to use carb based powders. I personally have never used powder supplements, but if I did I'd put it in the most fattening shake I can make. (When I do make what I like to call my "fatty shakes", I usually use heavy cream, some whole milk *so it doesn't get too thick*, ice cream *flavor is unimportant*, peanut butter and/or nutella, I will also sometimes add some pudding mix to it.)

Any protein powder would help. You can buy them in a drug store and even at Wall Mart.
Mix it with milk and cream and add some ice cream - just for the taste. Drink as much as it said for an ironpumper.
If you add some brandy it will work even faster

I would just take a 1/2 gal of ice cream and let it melt and pour it in a glass and drink it before I went to bed.

Never saw this done before but seems easy enough and sure to add weight fast.

I tried the weight gain powders but they tasted horrible to me and gave me a belly ache.
A good DQ blizzard 3 times a day worked for me.Yummy flavors and tons of calories.

Vin did get quite a pudge for that movie.
