My doctor - an experienced specialist in steroid usage - tells me that research (conducted, I think, in Canada or USA) showed that steroid users who remain on their steroids for a year without any breaks find
that their natural testosterone production does not kick back in even after a year of non-usage. He says their gland atrophies and they wither away alarmingly. I would like to hear from anyone who has first-hand
experience of this, or any medical specialist who has seen the research
data.
