The earlier post said 10-15 lbs ON THE BACK! That's simply impossible - end of story!

For a rare breed of genetic monsters, with optimal training and nutrition for a year, I can possibly believe 10 lbs lean muscle gained (except for absolute beginners, where the consensus seems to be that 15 lbs in a year is possible). But I'm sure the other 99.99% are delusional regarding how much actual muscle they've gained.
