I've actually been tested for HSV1+2, HIV, chlam, and everything else we could think of within the past couple of years. I didn't really engage in any risky behavior prior to that, they were just checking. Also, we've known my immune system wasn't really up to snuff since I was little. I have every virus and injury longer than everyone, that's just me.
I've been on HC since May 17th, started at 10mg a day, now at 25mg a day, so about five weeks total.
