my 12 year old is shredded, but he desperately needs to put on some weight. We've tried pushing food down his throat but it doesn't seem to be helping so I'm hoping I can get him to drink a few hundred calories. Back in the day, when I was in a constant bulk, I used to drink N Large 2 twice a day. It doesn't seem to be available anymore so I'm looking for recommendations on another weight gainer. Taste is going to be a primary concern since he's 12.
