Some sportsmen (body builder) are afraid that Finasteride might prevent the normal muscular development, is this true?
Finasteride is a medicine which blocks the transformation of the testosterone in DHT where the enzyme 5 reductase Alpha exists. The DHT rate in the blood decreases by 70 % and the rate of testosterone increases slightly by 8 %. The experience does not show any change as far as the secondary sexual characters are concerned. There is no feminization and the muscular mass does not decrease. We can thus reassure those who are afraid of losing their muscular mass when they take Propecia.
