A reader on Reddit answered it this way. Not a bad attempt but I can’t endorse it all. I see incidence reports that run from 1% to .1%. Here is the reddit response
0,02 % of people based on clinical studies made from pfs foundation….
This is 1 of 5000 people in lifetime during using
Of which medium time to get normal is 3 years…
3 years without medication, like trt proviron ecc
You literally have 50 more chances to die on a car accident
You have 10 more chances to die walking by street
And you have 2 times more chance to die choked on food…
So in reality is pretty safe like a drug, and to be even safer just do a blood work controlling your hormone panel….
Than after this every 6 months do hormone profile to check if everything is in range and you are good to go….
The majority of pfs, comes from hormone that was bad at the start of medication and during the medication they hormones get messed up (which can be seen on blood work) and they continue because they didnt have sides and then when they stop they body overact and pfs comes….
Other than that you can have once in a year a stop of one month, to wash the chemicals in your body, and restart again….
With all this literally the chances to get something its almost 0.
And in many reputablr clinical studies, after discontinuation of the drug, more people experienced persistence of sides on placebo grouo than the finesteride group….
Which doesnt mean that pfs fin sides doesnt exist, but many people nocebo themselfs to think that they have something which they dont, and many people have some problems in they body outside the drug
1 in 5000 is a real pfs, so if there is like 1milion consumers, we can expect that we have 200 pfs patients with it…
This number is so low, that doctors cant know how to take out this people from that, and this is why having blood work pre fin and during fin so that an endrychonologist will know how to bring you back in normal state if they have something to work with….
