I'm a serious weight lifter and want to know if Propecia could cause any fat gain or affect muscle tone? What other sidea ffects does it have?
Thanks

I've lost over 40# since I've been on Proscar (propecia). I don't know about muscle tone though- I haven't heard... I have been watching fat and carbs to lose the weight...

I haven't experienced any side effects...

Initially, I definitely gained strength and libido. Seems to have stabilized.
All of a sudden, so to speak, I can get bigger arms than I have before.
My guess is that I have more free testosterone in my blood now, and that is good for muscle development. Finasteride can increase testosterone in the blood by 15%, I've read. That is a mild increase, and has proven safe for me at least with no unpleasant side effects.
The body, however, has a way of compensating and reaching an equilibrium or tolerance condition where I believe basically testosterone levels return to pre-finasteride levels.
In early July, to "celebrate" my 1st full year on 1/4 Proscar, I will publish some pretty extensive results of my past year's weight, body fat, and such. I will also have pre and post testosterone levels available.
I think this info will at least shed a little light on this subject. I'm not sure what the results will be yet, of course.
My testosterone levels pre-finasteride were normal, and reflected an active male who lifts weights regularly but not religiously.
It'll be interesting what the "after" readings will be.
