the post from flybuy is interesting.. i'm curious to know if any of the other readers have has the same situation... i have been using top spiro for over a month and have no loss of libibo or other side effects. this could only occur if it made it's way through the skin and become systemic. since spiro is a diuretic, if that happed you would notice the diuretic effect.
finast doesn't work that same as spiro. spiro effects all androgens. finast simply interferes with 5ar and test doesn't become dht. it doesn't work by competing with androgens. like dutas it is classified as an azasteroid.
