best home-made weight gain shake?

[Eno]

well the good tasting ones usually have a pretty ridiculous amount of calories from sugar in them and pretty enthusiastic serving sizes - try myoplex MASS if you can find it on sale.. 500 calories and i personally don't think it tastes half bad.. get strawberry and toss in a scoop or two of designer whey.. and you got a 650 calorie shake that isn't too bad. drink two a day and you should be well on your way.
myoplex MASS label for you.
