I haven't experienced any side-effects at all other a slightly higher PSA count after the first few cycles so they had me go for a prostate biopsy just to be on the safe side & it came back negative. Since then, everything's returned to normal & things are great.
So, no rashes & no change in the shape of my jaw or anything else for that matter. As for hair loss though, just look at me:

I had a full head of hair a year ago.
LOL. Just joking, I've kept it shaved since my 30s. And, when I shave it my hairline is no different than it was two years ago when I began TRT. So, you should be fine when/if you decide to try TRT in a few years.
Good luck.
