The reason that I wanna consume mass gainer instead of whey is because I'm way way underweight. And I didn't know that mass gainer would have such a strong aftertaste.

In case u wonder, I'm 173cm and weight only 100 pounds/45kg.

Something to add on.I'm not like some random guy who takes only protein and don't do work out. I'm currently taking protein and hitting the gym.

Not that I don't want to get myself real food. If it worked that way I won't be that underweight d. Every morning I won't have appetite to eat food so normally I would just drink plain water. But if I drink some protein in the morning maybe I will get some nutritions instead just plain water. Rice ah eat until sienz d everyday rice, my rice portion sometimes also can eat 2 person one..
