jacobo,
Ive had a months supply of fluridil before...............maybe a couple of years back. Im nosy and like to look at and test stuff. Its relatively an elegant little treatement. They come in vials and they give you 2mls a day of the stuff. (Id rather have a sprayer, even though I know sprayers are kinda wasteful).
spironolactone can leave a little white residue, is much better used twice a day, can smell if you are working out and the frangrance covering its own smell gets diluted, etc. Fluridil is a more elegant treatment than spironolactone, but I "kinda" dont think its as effective.
I'd love to be wrong about that. I have seen three good fluridil pictures in which someone regrew some hair. However, if it had 100% androgen-receptor blocking efficacy, it should regrow as much as one would expect RU58841 to, and those pics didn't indicate that much regrwoth.
The question about fluridil is the water degradation. Fluridil is designed to degrade in water, and thus why you wont have side effects with it. However, to get the the dermal papillas, fluridil has to pass a water layer in the scalp, and human skin itself has some moisture. So its effective enough to show some regrowth, but is it as effective as spironolactone used twice a day? Hard question, I would conservatively say that spironolactone is better. I'd like to be wrong about that though.
Then there is the cost issue. Fluridil aint cheap. WHat is it now, about 40 a month or so?
