How is your E2? 250mg is on the high end of weekly doses. You could be aromatizing too much T into E. High or low E can decrease libido.
What is your T level at 250mg/wk?
How are you dosing? I’ve heard it’s better to do lower more frequent doses rather than high doses spaced out. Ideally, you take a short acting ester (ex cyp) every night before bed, to mimic the natural T cycle. Most T is produced at night and peaks in the morning. Some people say the more frequent dosing prevents too much E where they dont need an AI. Maybe try every 3 days at least.
I wouldn’t give up on TRT yet. It usually takes a while for people to dial in their regimen. And some people say it takes months for their body to respond. There is no telling whether your PSSD will respond to TRT, but generally doctors say that you can go up to 6 months on TRT before permanently reducing your natural T production.
Ive never tried TRT for my PSSD but I seem to have small improvements on T boosting supplements/lifestyles, so it might be in my future. Ive seen a few PSSD people try it without success and a few with.
