You will not be able to gain more than 4-5 pounds of muscle per year without steroids and growth hormone.

Did you mean per month? It is not hard to gain more than 5 pounds of muscle in a year...Did you mean per month? It is not hard to gain more than 5 pounds of muscle in a year...

This is actually a good point. If you are a young skinny type and do a progressive program of heavy back squats squats + deadlifts (and assistance exercises like pullups), and eat plenty of clean calories and do GOMAD (gallon of milk a day), sure you will gain some body fat but you will pile on slabs of muscle, waaay more than 5 pounds, all of it 100% natural.

The protein in the milk combined with the fat for some unknown reason causes steroid-like effects in the body. So you push even heavier weights, and get even stronger, and when you stop doing GOMAD you keep working out hard and the fat melts right off.
