Speaking from a medical stand point, unfortunately no type of steroid or HGH will help speed up the formation of new bone. Actually, if steroids are taken, they may even slow the healing process down. Best advice is to let nature take its course, unless you could convince your brothers Dr. to perscribe a bone growth stimulator. Most Drs will only perscribe them for cases where a non, or mal-union are suspected. It may be worth a chance though. We put our patients in them all the time.
