I think I draw the line at giving someone specific advice regarding how much testosterone they should be injecting themselves with. You shouldn't be doing that unless you have the relevant expertise and know the circumstances and goals of the patient and their medical history. In any other situation it's just irresponsible. However common it may be for random anonymous people in the internet to give out unsolicited medical advice, I can't agree that it's ok. It certainly doesn't contribute anything of value to the discussion.
