Hamburger meat. This is a tip from your mod. Why is it so good for packing on the pounds? Because it contains a pre-digested high quality protein that is easy for the body to absorb, as well as ample calories. Another bonus is that it is cheap. As I mentioned in one of my posts recently, calories are what really matters for growth, and not so much protein.
Grinding the meat to turn it into hamburger meat makes it semi-digested, and eliminates a lot of the trouble your stomach would have to dissolve the fibrous tissue of regular meat. This combined with the high fat content provides your body with the best source of relatively cheap and easily absorbed high quality protein and calories for gains. My best gains were on hamburger meat eaten everyday. You guys should give it a shot.
