How is it that the owner of this site is reputedly a fan of Revivogen, yet there are a significant number of people here saying Saw Palmetto "doesn't work"?
"Saw Palmetto Extract
Saw Palmetto has shown to effectively block the formation of DHT and is also believed to block the androgen receptors which are found on the hair follicles. Like GLA and ALA it also blocks Type 1 and Type 2 forms of 5 alpha-reductase and has shown to be more potent than Finasteride, the active ingredient of Propecia.

In the following studies Saw Palmetto extract was shown to inhibit both type 1 and 2 forms of 5 alpha-reductase (Finasteride or Propecia® only inhibits type 2), was more potent than Finasteride, and was able to effectively reduce binding of Testosterone and DHT to their receptors on various tissues. Please note that in the following studies Saw Palmetto Extract is referred to as Permixon or lipido-sterol extract of Serenoa repens (LSESr)
