The only things you need to aid in consolidation are daily multivitamins. Calcium, Vitamin D, Zinc, Vitamin C, Copper, Silicon, Phosphorus, Vitamin B6, and Vitamin K are all great for bone healing. A good amount of meat in the diet helps too.
There's no real reason to risk anything by taking HGH or even steroids (as asked in other threads). At most, ultrasound therapy should be the only thing extra if you really feel the need for it.
