Oh wow that's amazing. He must've been so brave to do that!

[Samantha]

I feel a lot would be proud of him, he battled the disease and won, not everyone can say that. He looks so much better now!

wish i could do something like this. i have the fastest metabolism and cant gain weight or muscle. big up to this guy.

I call ********. Fast metabolism or not you are still restricted to the human's biological structure. I doubt you are even eating 1500 calories a day. Try eating 3000 and you will definitely see weight gain.
For skinny guys, eat lots of food (no, you are not eating lots, eat more. I don't care what you are saying, more).
