For my six foot six inch build I'm a bit on the lean side.

I've made a 50 dollar bet with a local guy that I can make significant
muscle gains by March 10. He refuses to acknowledge that vegans can
gain a lot of mass.

If anyone knows any really good tips for gaining muscle, whether it's
a variation of sets, diet, additives, etc, then please let me know
about it. I need to back on some mass and show this bozo that a vegan
can put on the same sort of mass.

My body type appears to be mesomorphic so I think I've got a good edge
right out of the gates.
