I used it for approximately two weeks and experienced minor side effects, if you'd call them that.
I definitely noticed a lack of (perhaps weaker) morning wood after the first week, a minor hit to the libido, I also experienced watery semen which prompted me to stop. No one has really answered my questions as to what watery semen actually infers, so without hesitation I stopped taking propecia; fear of self-castration. I also fear I started to develop gyno but I'm not too sure about that in honestly. I only took 0.25 every day, just to be safe. I have stopped now and feel 100% fine.
I definitely recommend at least trying propecia because it could be your wonder drug. I recommend a dosage of 0.25 to be safe.
By the way I only started experiencing sides after a week.
