We are only able to give general advice as we do not know the entire DNA makeup of each person.
we are only talking averages that the person WHO WISHES TO GAIN MASS should be able to get to natural for that height.
I was a skinny scrawny kid all through high school at 5'11" and never got past 175 while in school.
I learned how to eat and trained and got to about 210 before ever taking any AAS
again, its just generalities. a 6 foot person that wants to be Mr Olympia should be able to acheive at least 210 before starting to add AAS to the mix
if someone whom is 6' and only 165, just wants to add 10-15 lbs of muscle, then they should easily be able to do that naturally cause a 6' frame should hold that without needing to use steroids to get there
