Tribulus Pro is a supplement marketed as a natural hormone booster for athletes. It contains 100 capsules, each accounting for one serving of 625 mg of the blend.

With this supplement boasting of Tribulus Terrestris as its main ingredient, is it really worth the value?

Here’s our take on Tribulus Pro’s claims.

About The Brand

Tribulus Pro is manufactured by Universal Nutrition, a New Jersey-based sports company. The brand has been around for quite a while, producing bodybuilding and sports supplements since 1977.

Universal Nutrition pushes sports nutrition forward as a vital aspect of the industry.

Main Ingredients

Tribulus Pro combines both Tribulus Terrestris extract and powder for optimum results. This supplement also uses active compounds including:

  • Sterols
  • Alkaloids
  • Flavonoids
  • Saponins

Other ingredients include:

  • Magnesium stearate
  • Dicalcium phosphate
  • Gelatin

Keep in mind that Tribulus Pro is produced in a GMP facility on equipment that processes peanuts, eggs, soy, and milk. If you are allergic to any of these ingredients, approach Tribulus Pro with caution or better stay away from it altogether, just in case.

Some users report an increase in testosterone levels after using Tribulus Pro. Does this mean Tribulus Terrestris works as intended?

Yes and no.

Tribulus Terrestris is marketed as a natural ingredient that boosts testosterone. However, research says otherwise.

Despite this fact, it's still possible that the extract in Tribulus Pro helps you with your testosterone dilemma in an indirect fashion.

Here we have two science-backed explanations of how it possibly helped some users boost their T.

1. Bulgarian Tribulus may Be Present in Tribulus Pro

As stated above, Tribulus Pro contains Tribulus Terrestris as one of its main ingredients. However, the brand didn’t specify the exact kind of Tribulus Terrestris this supplement contains.

Knowing the type of Tribulus Terrestris present in the supplement is important.

While it’s true that Tribulus Terrestris can’t help you boost your testosterone, some types of this extract can help you maintain a healthy level of T. Take, for example, Bulgarian Tribulus.

Bulgarian Tribulus works by inhibiting the effects of the enzyme that converts testosterone into dihydrotestosterone - 5-alpha-reductase. As a result, this helps to prevent your T from going below its healthy range. When you maintain a healthy level of T, it's possible to increase testosterone when you keep an active lifestyle.

On that note, Tribulus Pro most likely contains Bulgarian Tribulus. This could be the ingredient responsible for the reported increase in testosterone levels of some athletes and weightlifters.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

2. Tribulus Terrestris and Component X

As we mentioned, most strains of Tribulus Terrestris are ineffective in boosting testosterone levels alone. On the other hand, some studies reported that combining Tribulus with other components can lead to a slight increase in testosterone.

What other components, if any, are present in Tribulus Pro? 

It's hard to say, since the Supplement Facts label mention a Proprietary Tribulus Blend. It could be just Tribulus, or maybe a blend of Bulgarian Tribulus and Asian Tribulus, or maybe a bit of Tribulus and something else. Who knows?

In any case, the documented testosterone boost in some Tribulus Pro users could mean that a mysterious Component X is present in the blend, and that's why it works.

Other Health Benefits

Benefits of Tribulus Terrestris

  1. Improves Blood Sugar Control
    In one study, 98 women with type 2 diabetes took 1000 mg of Tribulus Terrestris daily for three months. The study reported that the supplement significantly reduced blood sugar levels in those women.
  2. Lowers Cholesterol Level
    The same study showed that the women taking the supplement experienced lower cholesterol levels than those who took a placebo.
  3. Enhances Libido
    Many people take Tribulus Terrestris for its ability to support sexual function, including libido. Various studies just prove how it can enhance sexual desire in men and women with a reduced sex drive. Keep in mind, though, that its effectiveness for erectile dysfunction is inconsistent, according to research.

How To Use

As a dietary supplement, you should take 1 capsule of Tribulus Pro daily with breakfast or dinner. Some customers take several capsules per day for better effects, but we recommend sticking to the manufacturer's instructions.

Side Effects

Taking Tribulus supplements should be safe for a short period of use. However, it may still cause side effects including the following:

  • Constipation
  • Cramping
  • Diarrhea
  • Exclamation Triangle
  • Exclamation Triangle
    Stomach pain
  • Exclamation Triangle
  • Exclamation Triangle
    Sleep issues
  • Exclamation Triangle
  • Exclamation Triangle
    Heavy menstrual bleeding in women
  • Exclamation Triangle
    Kidney damage in very rare cases

Most people don't experience any side effects when taking Tribulus Pro, but you should still be aware of these rare issues. Don't hesitate to reach out to your doctor if you feel anything out of the ordinary when taking this supplement.

The Verdict

We love how Tribulus Pro uses natural ingredients such as Tribulus Terrestris. This makes it relatively safe compared with the other supplements out there.

However, is it really worth the investment?

If your only goal is to boost your testosterone, then Tribulus Pro can be a hit-or-miss. While there are users who report a significant increase in T, there are also complaints about the supplement’s performance and ineffectiveness in other cases.

Here are what users have to say about Tribulus Pro:

  • Some shared how they got good results after using it long-term. This reinforces the idea that immediate effects should not be expected.
  • Some users also noticed that taking the supplement together with DHEA, sticking to a balanced diet, and taking fish oil kept their strength while they were trying to lose weight for a bodybuilding program.
  • However, some customers didn’t notice much difference whatsoever after taking the supplement.

As we explained above, Tribulus Pro may not directly increase your testosterone. However, it might help you maintain a healthy level of T IF it contains Bulgarian Tribulus.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

Considering the uncertainty of how it will perform its supposed primary function, the Tribulus Pro hormone-boosting supplement might not be worth your time and money.

An Alternative to Tribulus Pro

If you’re looking for a Tribulus Terrestris supplement and are worried that this one will be ineffective in boosting your testosterone, you might want to change your strategy and shift to maintaining your level of T. In this case, you might be better off with Tribestan.

Tribestan is a supplement with 100% Bulgarian Tribulus. As a result, it can help to inhibit 5-alpha-reductase (the testosterone-to-DHT converting enzyme) effectively in your body and thus keep your T healthy in a scientifically confirmed fashion.
