I had these pimples sort of things really, lots of sores all over my back for about 6 years, nothing i did would get rid of them.2 months into finasteride, theyre gone I guess it was caused by excess DHT or something !
body builders that take steriods and have an increase in testosterone get pimples on thier back. perhaps the finasteride killed off the testostorone that was causing the blemishes?
