I knew of a guy who had been on cycle for years with very few breaks and his natural levels were non-existence. He and his wife were trying to have a baby but because of his condition there was no way. So, this is what he did, bear in mind, I'm not telling you to do this, it's just what he did and it worked. He had been off all gear for nearly 8months but still nothing was working, so he got on a large dose of HCG very large, if I remember correctly, he stayed on it for 4 or 5 wks at 2000-3000 iu's ed. After that he got on nolva for another month, I can't remember the dose, but it seemed to work, he and his wife now have a little baby boy.
