I think you should definitely try and help him, especially if you know him personally. You could be the difference in him having kids or shooting blanks. He not trying to be ignorant, he just been misinformed. Shit if a doc told me something I'm inclined to believe them more than disagree with them. Before I joined this site I figured most docs would have some knowledge in AAS, but I've learned that most do not, not even endocrinologists.

After this if he doesn't listen then HE IS IGNORANT
