"The Beast 1200" is my favorite weight gainer, and I gained alot of weight on it over the years. It uses casein protein instead of whey, which is supposedly more time released and digests real well for me. I used to go through 4 jugs a month. Tastes good and its real thin, so you can chug it down easily. Awesome shit. Cant get it in stores. Dont have the website and phone number anymore though. Thought I did. If I find it again Ill post it up. I know the guys phone number who I get it from, but not about to post that. haha
