I do not take my hormones too far apart at all. So far they have always been administered by injection inside my doctor's office. He did redecorate once though, he moved the couch he has me sit on... so, I would say the farthest apart I have taken my hormones administered is about six feet, roughly. Give or take a couple feet. It can't be more than ten. Probably not less than four. Hard to say for sure. Six feet seems like a safe bet.
