There are isolated cases where people stop producing significant amounts of testosterone anyway. Danny Bonaduce makes his $ on shock, take anything said on that show or by him/his affiliates with a grain of salt. He also wants to be on testosterone for the rest of his life, and doctors in that echelon will propose anything to keep that kind of customer happy. Chris Benoit (the wrestler who just killed his wife, kid and then himself was also prescribed testosterone on the basis that his body was not producing enough. Take a look at his photo's and tell me he was being prescribed a dose of testosterone to supplement his retarded gland, it's all about the $.

There are substances you can take that will start your natural testosterone production back up again, clomid/chlomid is one of them. Bonaduce is an amatuer when it comes to steroid abuse, (though it is a major contributor to why he is so phychotic) I've seen and worked with the heavy hitters and the industry and never seen it actually happen. Countering that argument with more hear-say is meaningless.

I'm not saying it couldn't happen, but if there was a correlation to testosterone use, I think I would have come across in the hundreds of people that I worked with. Same goes for T3. It takes time but an otherwise healthy person's system will start producing again.

Now, if you were to take large amounts of testosterone for years on end, never taking a break, until you were 55, I could picture atrophying yourself so badly, at an age where the body has already begun to break down the recovery would be difficult...but someone that stupid reaps what they sow, and their experience cannot be used to estimate what would happen with proper use.
