Hey all, new member here. I used finasteride for 12 days in early September to treat hair loss. I had a couple of minor symptoms on it (brain fog, ball ache, some loss of libido) which came and went, but eventually decided to quit when I did some further research into sides.

A week after I quit I had my first crash. This essentially consisted of a 24hr panic attack during which I was unable to sleep. Luckily this insomnia only lasted a day, however the following week was filled with waves of anxiety which would come and go at random.

The next 2/3 weeks was okay… I started to notice some digestive issues and general fatigue but at least the anxiety/insomnia was gone for the most part, and in this regard I thought I was recovering.

However, at around the 24 day post fin mark, I had another MASSIVE crash - anxiety, insomnia, suicidal, anhedonia, shrivelled dick, incontinence, total loss of appetite, weight loss, muscle wastage etc. For about a week I slept only 1-2 hours per nights and was pretty much in a constant state of anxiety.

At the time of writing I am 5 weeks post fin and just about recovering from the mental sides of the last crash. I have managed to sleep well for 4 nights (no idea how long this is gonna last) and the brain fog is somewhat gone for now. My sexual sides have also mostly resolved for now (have managed to have intercourse a few times, no chance that was happening a week ago…)

However, my physical sides have pretty much continued to worsen. My appetite is back but I am still experiencing muscle loss, joint pain, fatigue, slight gyno and some nerve issues which I suspect is minor neuropathy (burning sensation in hands and arms).

Bloods wise:
My TSH and T3 are normal, however my T4 has gone from 12.6 before fin to 20.8 pmol/l (range 12-22). Indicates possible hyperthyroidism.

Testosterone: 9.6 nmol/L (Range: 7.6 - 31.4)
Free testosterone: 0.135 nmol/L (Range: 0.2 - 0.62)
Prolactin: 70 mIU/L (Range: 86 - 324)
SHBG: 51 nmol/L (Range: 16 - 55)

So looks like my test is very low and SHBG fairly high (though not technically out of range)

I have an appointment with an Endo on Tuesday (not that I think it’s gonna help) to go through my bloods and maybe get some other ones (eg DHT) done. I’ve had a number of people tell me this is all just caused by depression and I should jump on some SSRI’s - if only they knew :upside_down_face:. Think my best course of action is to wait and see what happens… I will try and update this weekly in the meantime.


Hey @infinite,

I’m sorry to hear that you’ve been going through this awful experience. All of the symptoms you’ve described are commonly mentioned here.

I unfortunately don’t have any first-line treatment suggestions to offer you because we don’t know exactly what’s going on (yet) and there is nothing that truly has a reliable track record of being effective.

That said, I want to advise you to try not to obsess over the numbers too much or have high expectations when visiting specialists such as endocrinologists. While it will not hurt to check your hormone levels via a blood test and see if there is anything you might be able to improve, we currently have no reason to believe that there are any notable or consistent overlap among PFS-patients’ blood-hormone panels. Despite the plethora of symptoms, your hormone panel may return pretty much normal, as it does for most people.

Additionally, the issue is still often disputed by medical professionals and you may be confronted with skepticism and be told that these symptoms are likely psychosomatic in nature, which I can assure you they are not. While I wouldn’t advise anyone to delve into a back-and-forth with their doctor(s) about this, I’m just mentioning it to prepare you for possible disappointments.

In any case, take good care of yourself to the best of your ability, and as I’ve said before I hope things will improve naturally for you in the coming months. We often see people report here and then recover in their first half year or so. So try to give it some time.

Welcome to the forum.


Hello @infinite welcome to the forum. Sound advice from wintermoon Time is very important given where u are (very early on) you have every opportunity to recover. One thing I would add is that you report your symptoms to the MHRA via the yellow card scheme underreporting is what keeps this fucking shit on the market. It only takes 5 minutes.



Thanks for the welcome guys, and yeah I’ll deffo report it Laz.


UPDATE - 6 weeks post fin.

My Endo confirmed I have PFS and told me to wait 3 months.
My symptoms have kind of fluctuated a bit.
Better - brain fog, anxiety, sleep, burning sensation in hands, body temp, fatigue (maybe)
Worse - muscle loss, skin sensitivity, depression, most sexual sides

This is the week that things finally sank in. Might be because my head has cleared a bit.
I’ve gone from hope, to despair, and back more times than I can count. The thoughts of PFS are virtually all consuming. I find myself zoning out of conversations etc, this is something I definitely need to work on. I think a significant amount of my anhedonia, depression and lack of motivation is actually due to this - i.e if I didn’t know what PFS was I would likely feel somewhat better mentally. Still, it pains me to see pictures of myself only 2 months ago and to imagine what I would be doing now if fin didn’t exist.

Sorry for the venting guys, I know you’ve all been here before. You are amongst the bravest and most resilient people I’ve ever come across, and I hope that I can emulate that mental fortitude in the coming weeks/months.


So turns out that during the 2 weeks leading up to my big crash, I had been taking a multivitamin with 400x the recommended vitamin B12 dose. And using ketoconazole shampoo. Yep, a methyl donor known for worsening PFS and a 5ARI. Just my luck :confused:

I hope you’re okay, I’m here for anything.

How u feel today?

Mentally I think I have plateaued. Managed to start working again this week (although my cognitive abilities seem to have declined somewhat compared to pre PFS, especially train of thought/conversations). I will be starting a diet and/or attempting a water fast at some point.

Physically it’s harder to say. Certain symptoms come and go (for instance I dont have the nerve pain I had a few weeks ago, or cold sweats). But the main one (muscle loss/body composition change) has continued. I don’t expect this to stop anytime soon unless my muscles miraculously regain their androgen sensitivity.

How are you doing Henrique?

It’s been 2 months and 2 weeks since I had the crash. I’m on my sixth dose of TRT. My muscle pain has stabilized, my weakness has improved a lot, but it comes and goes too. For a few days now, I have noticed less genital sensitivity, less libido and cognitive problems with reading, difficulty maintaining focus in a conversation. My muscles are still limp. I’m not working, but I plan to go back to work next year. My mother has helped me a lot. Day 11 now I have a doctor and let’s see what direction we will take. Note: I cannot guarantee if the stabilization of my muscle loss was natural or if it was due to testosterone. I’ve had a few mini-crashes, waking up suddenly with a feeling of shock through my body and a racing heart.

UPDATE - 9 weeks post fin.

Saw a nutritionist. While I agreed that reducing gut inflammation would help, I also had to spend 10 minutes trying to explain why high dose B vitamin supplements would make me worse. It is quite infuriating trying to explain PFS to someone who is convinced it is nothing more than low T and an imbalanced gut. Anyhow, I’m now trying a Paleo diet.


  • Dry skin has improved
  • Muscle loss has slowed/weight stabilised
  • Can respond to alcohol
  • Higher libido
  • World Cup starts today

Not so positive:

  • Transient pain/burning in muscles
  • Pain in balls, also sometimes when urinating
  • Collagen loss
  • Still tired most of the time

Although my neurological symptoms have plateaued, this is still a pretty awful baseline, and these are surely the worst of my sides. Low stress tolerance, difficulty concentrating, lack of motivation, partial anhedonia and so on. My brain function is currently a crude simulacrum of its former self - I honestly feel like I have lost 30 IQ points. Luckily I am still able to enjoy music, movies and watching sports - I really hope this remains.

Social interaction is much more difficult, and requires substantial effort. In a former life I was very confident, extroverted and always up for a debate. Nowadays I hardly contribute to conversations, and have much less to say about topics and interests I once held dearly. This makes socialising a double edged sword - while it can improve my mood, it also has the simultaneous effect of reminding me of how much worse I now am at it! Despite this all being caused by a lack of neurosteroids, I am hopeful that my brain will be able to partially adapt with increased exposure to situations I find uncomfortable. Interestingly, when drinking alcohol the other day I felt the closest to normal since the crash (GABA and all that).

I am lucky to have a loving GF who is very understanding. That being said, I am unsure how long that can last given my current predicament and likely non recovery, although perhaps I am being overly pessimistic.

In summary, this condition is absolutely horrible. I really hope Donald Trump gets it (actually on second thought, I don’t even think he deserves this!). I’ll post another update when I hit the 3 month mark.
