PrEP and transitioning

[GingerVicki]

I have a couple of questions.

I've read that PrEP is about 22% less effective for transwomen then homosexual males. Has anyone else heard anything like this? I misplaced the website (not sure how else to say it) but it seemed very relevant, current, and official.

Also, I've heard that people who take PrEP usually lose weight, but I can't seem to prove that via reliable sources. Anyone have any personal answers or recommendations?
