Accidentaly, I took a blood test at 16 June, under the treatment of fin, the score of “CK” was very high(864). (I have experienced muscular pain on whole body.)

Tell us your story, in your own words, about your usage and side effects experienced while on/off the drug.

Hello. pardon my poor English.

I am a japanese man, living in Tokyo, 35 years old. I am studying jurisprudent and philosophy at university.

Since 13 May 2023 (about three months ago), I took finasteride 0.25mg/day for a month (until 23 June). Before taking it, I had researched japanese medical articles about Finasteride exhaustively by using data base of University. But there is not a single word of PFS. So I thought it safety and took it and then halted(stppped). last one week during the treatment(taking finasteride), I suffered from leakage, then I discontinue treatment. Accidentally, I took a blood test at 16 June, the score of “CK” was very high(864). (I have experienced muscular pain on whole body.) After discontinuation, such symptoms almost got well in few days.

But, one month and a half had passed since discontinuation, I got suffered from sexual diesease(Erectile dysfunction and impotence, Decrease or complete loss of sex drive, Orgasm disorders such as sexual anhedonia and loss of pleasurable orgasm, Ejaculatory disorders), and, being dying exhausted, a terrible headache, and had lost emotion. It was what you call the first crash(12. 8. 2023〜19. 8. 2023). Then, after the crash, I quickly and partly recovered from such symptoms, that is, I almost recovered the function of the sex organs temporarily(20. 8. 2023), and some of the other symptms(headache and dying exhausted )went away. But unfortunately, I soon got suffering from sexual diesease again (it is not perfectly lack of function, but very weak) and still loss of emotion and passion. And I am suffered from cognitive problem. It means death for me.

I think this may be the PFS. So, What is to become of me? Is there any possibility that I avoid the PFS yet?🥲 Or there is no hope?

I skimmed through this report just now…
Okey…So, in my body, AR is extremely overexpressed by 5αRI and then I was crashed (Cessation of finasteride will result in a surge in androgen production owing to the newly uninhibited 5a-reductase enzyme. Presuming a 60% reduction of basal DHT levels during finasteride use, cells epigenetically adapted to a depletion of androgenic signaling owing to the pharmacological reduction of DHT would be exposed to a 300% increase in DHT upon cessation…With a greater concentration of receptors, the organ becomes more sensitive to testosterone and at a certain point, paradoxically, that sensitivity may shut down.). And now after crash it looks completely hopeless…🥲

Can not we put the overexpressed AR back to the normal? Is there anything what we can do for reconstruction?

There is always hope. GIVING UP cannot be an option.

hi, Henrique. nice to meet you.

Yeah…You may be right. I also told me so ――until I read the article “PFS: Manifestation of a Post-Androgen Deprivation Syndrome following exposure…”.

I sincerely want to believe the existence of Hope or Chance. But I have already got crashed and got suffered from typical symptoms … According to the theory of the article, It signifies that AR is terribly morbidly over expressed… I can not imaginate any way of recovery from this Deadlock situation… Or is there any efforts to down-regulate the overexpressed AR into normal level again?

I would really like to have answers to understand what happens in our body, but unfortunately, I don’t. We need to support studies and try to lead the healthiest life we ​​can. I’ve been losing muscle for 1 year. Some symptoms naturally improve, others remain.

Dear Henrique.

I have read your story now…
You are definitely strong!!
thank you for your comment.

Thank you for sharing your story. As Henrique mentioned please don’t lose hope. We have world-class researchers working on PFS. There’s a study going on in Germany looking more into the androgen receptor and epigenetics like you have read into. There’s also a genome study that we are currently fundraising for. You can read about it at:

Please stay strong! We are all in this together.


Donate to pfs network monthly ask family friends to do same. Atleast 100 dollar a month.

Research is progressing.


まさか日本の方と会えるとは!恥ずかしながら私の英語力はお粗末なもので…。おすすめ紹介ありがとうございます🙇 アドバイスもありがとうございます。

ともかく本当に困りました😥 とても現実の事とは思えないです。ついさっきまでここにあった私の人生が、わけもわからないうちにもう永遠の彼方へ失われたなんて… そしてそれよりも先に目の間の耐え難い身体的苦痛に私は負けそうです… 希望は捨てたくないですが…

hi, Toughluck24, thank you for your encourage.

I hasitate to say that I can not send money. Now, I am extremely poor…to tell the truth, I have no job because I got terrible accident 8 years ago and heavy aftereffects…what’s more this nightmare😱 I am so sorry.

I will do what I can instead. I learned a lot and tried to understand PFS. Yesterday, I visited the endocrinology department at the university hospital that prescribed Propecia for me, and I told them what I found out, i.e. what roughly is happened and why PFS is hard to cure, and asked them for additional hormone testing and cooperation. The professor voluntary wanted to read the PFS papers, so I handed them all over. Of course, it is probably in the distant future that treatments will be established, but at least the university hospital will probably no longer prescribe Propecia, at least without strong warning of PFS. I think I saved a lot of the next victims, so I’m sure I’ll go to heaven. Well, I am proud that I have always done good deeds :joy:

I will look for good treatments with doctors of the hospital.


If donations are too difficult, maybe consider telling your story on the Moral Medicine youtube channel which some of our members have made. Awareness is very important.

Great to hear the endocrinologist is interested in reading the papers at least. We have to do everything we can to convince the medical community.


Yes, if you cannot donate we’d love to have you share your story on our youtube channel @aki
