Tribulus Research and Studies
Much tribulus research and studies have
been conducted, and there are some contradicting results regarding the positive benefits of
supplementing Tribulus Terrestris.
There's always controversy and contradicting advice on the effectiveness of tribulus terrestris. Obviously, the marketing materials you read from supplement makers will tout the effects and benefits of tribulus like it's a miracle herb; and then on the other hand, talking with other like-minded fitness individuals, and just simply browsing bodybuilding chat forums, you'll find a wide range of opinions on the subject, and I'm no exception.
Please keep in mind here, that my take on tribulus is purely personal opinion, and only based on my own past and present experiences of using various tribulus based supplements. It by no means, is a verdict on the effectivness of the herb.
There are a large number of studies that provide contradicting results on the effectiveness of tribulus. Various studies on rats have demonstrated that tribulus increased testosterone and sexual activity 1, 2 , while other studies found that tribulus had no effect on muscle strength, body composition, exercise performance in human subjects 3, 4. Obviously, taking these studies at face value, the studies involving human subjects would obviously carry more weight compared to the studies involving rats and other animals.
However, from personal experience, and based on user reviews of various tribulus based supplements, I would have to say that tribulus works, but not for everyone. Enough users have submitted postive reviews to show that tribulus based supplements do work. I can say from my past experiences that each time I've taken a tribulus supplement, I've noticed a difference - these include increased acne breakouts, and increased libido etc...
