I have used Tongkat Ali from other suppliers about 8 years ago and had quite good results in male stamina. I am now 63 and have had a couple of bouts with enlarged prostate and the problems that occur with that. Taking suppliments to help relax the prostate and full elimination has worked well for me, but when I drank the Tongkat Ali it caused a reversal of what the suppliments are doing and an enlargement of the prostate glan, thus hindering complete elimination. I think this is a wonderful product for the younger men, and woman. It will put a sizzle in your emotions and affection for each other, but I do caution those who are struggling with several trips to the bathroom at night.
