I have been using a product called \"Tribulus Stack\" from Twinlab. I have found it very effective, but
A. The tribulus is an extract made to scientifically proven specs
B. There is a healthy dose of DHEA in that \"stack\".
Lately I have been taking the two supplements separately to save money, but the same basic idea, raise testosterone in an old boomer like me. I cycle between the trib stack and various andros.
Kids, don\'t even think about this please. In fact if I were under 40, I wouldn\'t even mess with this. After that, you have to weigh the risks of old age against the risks of messing with these supplements. If you can afford a doctor who knows what he is doing and can monitor results, that would be ideal.
