I've used Testosterone replacement for 23 years. Started with patches that caused red rings where they were applied. Moved on to Androgel, which is like an alcohol based cream that you simply rub on your shoulders in the morning after a shower. Androgel is far and away the best replacement I every had, but it's on patent and without good health care coverage you'll never get it. Currently I'm back on the shots. I've tried to do them myself, but injections in my leg cause it to swell for a week after the injection. So I visit my local clinic very other week and they give me my shot in the rear. It doesn't even cost me anything out of pocket.
