post anastrazole crash on a pfs sufferer? Need Help.

TL;DR: Long PFS history since Nov 2023 (fin crash → partial recovery on TRT for over a year, doing well). In June 2026 added anastrozole (3-4 doses over ~3 weeks) to a 300mg test + masterone protocol → crushed my E2. Dropped test dose from 200mg to 100mg/week in July to try to fix the T:E2 gap, added HCG 500iu EOD. ~20 days later developed a new, severe symptom cluster: joint pain, dry mouth/lips/skin, frequent urination, worsened tinnitus, insomnia (new — never had this before), full-body muscle twitching, increased body hair, worse speech/brain fog/anxiety, flu-like symptoms, cold hands/feet. Not sure if this is a fresh crash from the AI, or from dropping test dose (less substrate to aromatize), or both. Scared this is Post-AI Syndrome / permanent. Need input from anyone who's navigated this.

Background: PFS since Nov 2023 (fin, even short low-dose exposure, crashed me hard each time confirmed on rechallenge). Recovered substantially through 2024 on no treatment. Started TRT Jan 2025 (200mg/week) for residual Pre mautre ejaculation did very well on it for over a year, best I'd felt since PFS onset, aside from persistent tinnitus. Ran 500mg/week + masterone briefly in late 2025, no issues. Back to 200mg/week through early 2026.

What changed June 2026: Bumped to 300mg test + 100mg masterone/week, added 0.25-0.5mg anastrozole only for 2 weeks, 3-4 AI doses total. Masterone gave no results (possibly already acting as a mild anti-estrogen itself), and between that and the AI I believe I crushed my E2.

July 2026 the new crash: Developed severe anxiety, no dopaminergic response, libido gone, genital numbness/no blood flow, cold glands. Bloods: TT ~2000 ng/dl, E2 only 46 pg/ml at trough (should be closer to 100 on that dose given my normal ~20:1 TT:E2 ratio). Cut test dose 200→100mg/week to close the gap, added HCG 500iu EOD (helped briefly, now stopped helping).

~20 days after the dose cut, new symptoms appeared: joint pain (elbows, knees), dry mouth/lips/scalp/face, dry foreskin, frequent urination, tinnitus spiking, new insomnia/fragmented sleep (never had this before), full-body muscle twitching, increased body hair growth, worse speech and brain fog, flu-like symptoms with runny nose, cold hands/feet. Losing muscle and glycogen fast.

My question : Is this a continuation of the AI crash, or is it a separate effect of dropping my test dose (less aromatizable substrate on top of an already-suppressed E2)? Everything was stable from 2024 until I touched anastrozole in June I'd used it before on a 500mg/week blast without any issue like this. Should I come off test entirely, go back up in dose to give E2 more room to aromatize, or hold and wait it out? Has anyone recovered from a crash like this, especially the joint pain / insomnia / dry mucous membrane cluster?

I've read about people developing permanent estrogen receptor damage from AI use and it terrifies me I know of a few people in this community who didn't make it through something similar. I had clawed my way back to feeling mostly normal by June after years of this, and losing that in a month has been brutal. If anyone has real experience with this or if anynoe can give me any guidance what should i do next? should i increase the testosterone to make room for aromitastion or should i stop the testostreone altogether or should i change ester the for faster aromitastion or should i add dbol or e2 valerate to increase my e2?? please help me i cant continue like this. i Used to so handsome and happy before but this low/crsuhed e2 has taken life out of my body. i dont find joy in anything, i cry everyday seeing my body like this. One thing i know is that i had got better from the pfs crash with time but this time i am on exogenous testosterone i dont know what should i do alleiviate my symptoms? Please help me, Please !
 
My initial thought is that you are bouncing around way too much with your protocol so your body is responding accordingly. With regard to the newest symptoms, it’s likely due to the drastic reduction in test doses. In less than a year you’ve gone from 200 to 500 to 200 to 300 to 100. Your blood levels with continue to decline for 5 weeks as your body calibrates to its new steady state. Not to mention the other compounds you’re haphazardly throwing into your protocol.


My thoughts would be to simplify things so your body can find homeostasis. Bump the dose back up a little and cut out other compounds except maybe HCG, but even with that I would only add after about 8 weeks on a steady protocol. And don’t freak out. The human body has an incredible ability to heal itself, but you need to stop sending it on a rollercoaster with all the wild adjustments you’ve thrown at it.
