Depends on the individual and where you are at with your genetic potential. Are we talking about 2 people who just started working out, or someone who has been training for years. Noobs are gonna gain much easier. Hell I went from 160-200lbs in my first 2 years natty. That was 15 years ago. Hvae only been up to 270 since, even on teh juice, but my body likes to stay around 250.
But to answer your question, stfu and gtfo.
