So I am trying to gain some weight and drinking some weight gain shakes (have like 900+ calories each). For those who know, if I pre-made like 8 drinks (blend the powder + milk), then stuck them in the fridge right away, will they go bad? I find myself not taking them because I hate making them ALL the time, but if I can make a huge batch and then just whip them out and drink them whenever, I would actually drink them all the time. Anyway know?
