A recent study in Massachusetts found that the average middle-aged man loses nearly 2% of testosterone levels each year. 2% does not sound like much, but over time it becomes significant. A decrease in testosterone levels decreases libido and energy levels and also softens muscle into fat.

Thankfully, there are testosterone supplements that can offset testosterone decreases. However, not all of them work. In fact, our research has found that only about 5% of testosterone supplements can have a significant impact on your testosterone levels. Tribex are the latest testosterone supplement to hit the market. But does it work?

Tribex Ingredients

Tribexis comprised of 840 milligrams of the “Tribex Formula,” a proprietary blend made of :

• Does not require a prescription

The Cons

Tribex is not for everyone. The website contains the following warning:
Do not take if you are a female, especially if pregnant or breast feeding, elderly or under the age of 18, chronically ill, or taking any prescription or over-the-counter medicine, including but not limited to antidepressants (such as MAo inhibitors), stimulants, allergy medications, and medications for high blood pressure or other cardiovascular conditions. Discontinue use if you experience dizziness, headache, nausea, or heart palpitations. If you have trouble sleeping, do not take within 6 hours of bedtime. Keep Out Of Reach Of Children.

Price and Guarantee Policy

One bottle of Tribex can be found online for around $32 plus shipping and handling. $35 for a testosterone supplement is a relatively inexpensive. That being said, Tribex does not really offer anything that separates it from the competition.

We also were unable to find a money back guarantee, unfortunately.


Tribex appears to be a decent testosterone supplement. It contains several testosterone-boosting ingredients that can help if dosed correctly. However, there is no way of knowing just how much of ingredient is contained and there is no way of knowing if it includes a quality grade of Tribulus Terrestris.

Tribex may help boost testosterone levels, but we are wary to recommend it with so many question marks regarding its effectiveness. There are much better testosterone supplements available. If you have tried Tribex in the past, please tell us about your experience in the comment section!
