I had an awful experience with this herb several years ago. In my opinion, a man interested in having powerful erections, balanced androgen production, and great orgasms should avoid this herb, because it shuts down DHT production(the king male androgen), which has drastic affects on male libido and sexual energy. Just google "Saw palmetto erection problems" and read the unfortunate experiences of other men. If you're taking it for prostate health, switch to stinging nettle root extract. Cheers.
