I've been taking this herb every other week at 500mg/day and notice increased sexual energy, stronger erections and orgasms. Pretty potent stuff. My accupuncturist suggested that this herb is very "yang" (hot) and that cooling "yin" herbs may be needed to balance (such as schizandra). ps. I also like knowing that the deers don't seem to be hurt in the antler trimming process.
