This site clearly says that Saw palmetto does not reduce dht blood serum and will not stop any hair loss but they rate revivogen as an excellent alternative to propecia as well as crinagen...its funny because they both use saw palmetto, if it doesn't work why are they putting it in there??? especially when it has been proven that topically, saw palmetto is just not absorbed to the extent it would need to be productive. I think this hair website is just being run by sponsors so I can't really depend on the reliability of it. Who owns this site anyway? I bet propecia or revivogen.
