My son has SMBA
Has anyone tried 17-AAA to retard progression? How about lowdosenaltrexone ?

I am not familiar with either of these items. Before taking anything, I would recommend checking with your son's neurologist if he/she is familiar with KD. If not, contact someone who is quite familiar with the disease. It was only a few years ago that some doctors were recommending testosterone pills or injections to help with strength. Now we know that testosterone does much more harm than good. If you cannot make contact with someone, please let us know and we will ask our Scientific Review Board.
