What to do with Mass Gainer?

[WorldClassDBag]

To clarify my friends bought me a 10lb bag of mass gainer from GNC. I didn't ask for it but they bought it for my birthday. I have no idea what to do with it. I can eat 5000 cals without an issue so it isn't really neccesary. So what should I do? I don't wanna toss it out and I doubt anyone wants to buy it. Can't return either. Do I just say fuk it and use it?

Use it as your postworkout shake (it is high in carbs / protein)

Use it post workout, use it whenever in order to add calories to your diet and hit your macro numbers for your goal of gaining weight. For example if your bulking your carbs and calories will be higher so to hit those numbers you factor in your weight gaining shake in order to easily achieve those.
