6'1' or 185cm and I do not believe I am small for an asian guy. I did grow up with a half-asian diet. Testosterone in men is never a problem as long as you eat enough and excercise when growing (And as long as you don't suffer any congenital disease that messes up your hormone system). Peak testosterone is reached at 20 years approx. and it's also when the body stops growing. Higher testosterone levels during younger ages can stun growth (Since it deposits more calcium in the bones and they stop stretching).
Starting at 20, the skeleton reinforces itself until 30 and then the skeleton only gets weaker. High-impact excercises are recommended to increase bone strength and prevent brittleness during aging.
