yes those numbers get very small but I am a believer that the body can't heal until all of the hormone is gone. Sust is just a bad choice if your going to come off.
What do you mean "heal"? Are you saying testosterone will damage your body or do you mean the body can not restart HPTA axis before the hormone is completely out of your body? I can get test gel 50mg/pack and still get my own production back. Docs own words. You don't have to be squeaky clean to start getting your hormone production back.
