I'm trying to gain mass. 47kg 170cm right now. Goal is 60kg. To make my gain easier, i've decided to drink 1-2 cups of protein a day. Yes i know lean solid meat protein would be a better option but i don't have the appetite to swallow that much food in a day and also i don't have much time to prepare them.

I'm targeting around 2,000 calories a day to start off for now.

So back to the point, should i go with whey 100% (only 120 calories / serving) or mass gainer like BSN true mass (420 calories / serving '2scoops').

Will mass gainer increase my bodyfat with a large margin compared to whey? Since my point is gaining lean mass it's kinda confusing should i go with whey or mass gainer for the big calories gain.

Trying to !
Not for me dude. I can have a decent 400 calories meal and don't feel like eating for the next 8 hours. Been eating 1 or 2 meals a day for a pretty long time.

Anyway, lets not discuss about substituting real food i know it's better but i'm only into the option of choosing between whey/mass gainer.
