Ok is this natural limit with a low bodyfat(7-10%?)
Isn't there another natural limit with higher body fat(13-18% on up?)
Couldn't juice help you get to your other natural limit and trick your body into keeping that muscle without all that fat, which you could easily get if you chose to be a fat ass?
Wouldn't the body naturaly hold more LBM with alot more fat, knowing it has the back up energy stores to have energy for all that LBM?
I'm not even tallking about 5%, just being lean. I think the body hates to have all that muscle and not alot of fat and has to be tricked into a new set point.
So someone that is 5'10" and just ate and ate and ate and then trained(no anabolics) could get up to 300lbs and have alot of muscle and fat.
Someone can also cycle and end up at 220 at 5'10" and have the same LBM as the guy at 300#, but has trouble maintaining it because he doesn't have enough fat. Not that he is 5%, he could be 9%, the body just doen't think its right.
I think it takes time for the body to see it can survive at that "FAT NATURAL LIMIT", once you over come the time factor, you should have no problem!
