I've read a little about him and his work with many veterans suffering from traumatic brain injuries. I've read where he says he starts them off with 60mg a week doses. He says he uses such low dosage amounts so he doesn't completely shut down their own system. Is this really possible? I thought once someone took any amount of exogenous testosterone it shut down their own production? It's interesting to consider his apparent success with so many men suffering from TBI's with such low dosage amounts. Just curious as to anyone with knowledge of Dr Gordon and his strategy to give just enough testosterone while not completely shutting down the bodies own production.
