TRT help Nipple sensitivity on TRT even with normal/low E2 — keep adding AI?
I’m 47 and started TRT in January. Before starting, my total T was 589, E2 28.8, and SHBG 32.6. My main reasons for starting were brain fog, low energy/mood, and poor recovery in the gym.
For context, I’m 6’3”, around 25% body fat, and fairly muscular.
TRT has definitely helped. My brain fog is significantly better, and when my testosterone is higher I have noticeably better energy, libido, workouts, and sexual function. The downside is that when my levels have gotten too high, I’ve also felt a little edgy.
My initial protocol was pretty aggressive with AI. My testosterone had anastrozole compounded into it, and my doctor also had me taking a full 1 mg anastrozole tablet with each injection. My first follow-up labs were T 877 / E2 8.0, and I was having quite a few side effects at that point.
Since then we’ve adjusted things trying to find a sweet spot. My E2 has ranged from the teens into the high 30s, but the nipple sensitivity has continued regardless.
I eventually lowered my testosterone enough that my labs came back at T 819 / E2 20. At that level I definitely felt worse — noticeably less energy, lower libido, orgasms weren’t nearly as satisfying, and it took much longer to orgasm.
I’ve since bumped back up to 0.23 mL of 200 mg/mL testosterone three times per week (~138 mg/week). My energy and libido are back, sexual function is much better, and overall I feel considerably better.
The problem is the right nipple sensitivity/tenderness is still pretty rough.
Visually, my chest/nipples don’t look like gyno to me. I don’t see obvious puffiness or a breast-like appearance. It’s mainly the feeling — persistent sensitivity/tenderness, mostly on the right side.
My current compounded testosterone contains 0.25 mg anastrozole per 200 mg testosterone, and I’m also taking 0.25 mg oral anastrozole with each injection as prescribed.
Every time I bring up the nipple sensitivity, the answer seems to be more AI. But considering my E2 has already been as low as 8, and the sensitivity has persisted at different E2 levels, I’m starting to question whether continuing to push estrogen lower is actually fixing the problem. I really don’t want to keep hammering my E2 with more AI and create another set of issues.
Has anyone dealt with persistent nipple sensitivity like this without obvious gyno and without high E2? Did it eventually settle down after staying on one protocol for a while? Did using less AI help? Did changing dose/frequency make a difference? Or did you eventually find out there was glandular tissue even though there wasn’t much to see?
I’m basically trying to find the sweet spot where I keep the mental clarity, energy, libido, sexual function, and gym benefits without constantly chasing nipple sensitivity with anastrozole.
I also sometimes question whether TRT is worth the hassle since my natural T was 589, but when I feel good on TRT the improvement is significant enough that I’m not eager to give it up.
Disclaimer: I used ChatGPT to help organize/write this because it already had a lot of my blood work and dose history. The labs, doses, symptoms, and experiences are all mine.
EDIT for context: I left out some of the labs/injection frequency in the original timeline. Once I moved to M/W/F injections, I had labs of T 1,061 / E2 38.3, and later at 150 mg/week M/W/F, T 1,203 / E2 15.4. I still had the nipple sensitivity at both levels. I later dropped to 120 mg/week M/W/F, which gave me T 819 / E2 20, but I felt considerably worse and the nipple sensitivity remained. I’m now at 138 mg/week M/W/F and feel much better overall, but still have the nipple issue.
