I fully agree about the 30lbs in 4 weeks are bullshit
Think about it logically if everyone gained 30lb on a cycle, how big would they be after 10 cycles, about 300lb plus their original body weight. It does not make sense.
Lets say they gain 30lbs and loose 20Ibs of water after 10 cycles that’s still 100Ib and I don’t think there are a lot of people who have gained 100lb of pure muscle.
If, I made 4-6 pounds of “muscle” in a cycle, I would consider it a great result.
Be happy your doing great
