Thanks WarLobo, that's what I was looking for!
So does "muscle maturity" just come with time, provided one sticks to a consistent diet and training program?
Say I reach my desired muscle size, but I keep training and eating consistently, and pushing myself in terms of strength and definition but not size, will I get muscle maturity and that nice hard oak look over time?
Or do you have to reach your genetic peak size-wise before you can develop muscle maturity?
