Tribulus is known to increase libido, and may cause changes to general mood.
- Huge dose of tribulus in each serving
- Black pepper extract may improve absorption.
- May not increase testosterone unless the user is infertile
- No other ingredients.
Tribulus is a very simple formula which uses a massive dose of the tribulus plant in an effort to boost testosterone levels.
Although it’s a great dose, the research says you won’t get any testosterone increases unless you’re an infertile male.
That being said, if you’re strictly after libido enhancement, this supplement may work for you.
Underground Labs also produces a more complete testosterone booster called Roidz.
