See, this is how little I know about this stuff. LOL It's 200mgs per ml. Here's the backstory: Started with 1 ml once a week. I asked if I could divide it into two doses 1/2 ml at a time twice a week. The answer was yes. He did a peak and trough test and my trough was high so he cut my dosage in half. So for a month or so I was doing a 1/4 ml twice a week. We did another peak and trough and the trough was normal but my free testosterone was a little high. I told him I felt better on two 1/2 ml doses a week and that was fine with him he said he'd have to keep an eye on my hemoglobin I think is what he said and I'm back to my twice a week 1/2 ml.
I would think that would be enough testosterone to get and and maintain an erection but the problem persists and then the orgasm issue is still there as well. I have no idea what could be causing this. The only thing my doctor said was "the brain is the biggest sex organ in the body." That didn't help.
