Don't worry. I've actually discovered the secret to gaining all the muscle mass you could ever want....
Eating tons of healthy foods while putting in the work it takes to put on real muscle.
That's all there is to it. There aren't any special tricks everyone is hiding. Just load up on healthy foods. Try getting in like 3000-5000 calories a day. Then lift hard 3-6 days a week.
