Testosterone replacement therapy is a booming industry with hundreds of products on the market. While some of these supplements are backed by solid scientific studies, others are based on shoddy formulas that are ineffective and harmful.

Testro-X is one of the latest products to come on our radar. The supplement seems to have a good number of users reporting it to be very helpful, while others are more skeptical about its formula. Confused about what to believe, we did our own research and prepared this comprehensive review for you.

What is Testro X?

Testro-X is a natural testosterone booster from Umzu. The supplement is formulated to stimulate your body to produce more testosterone. In other words, Testro-X does not contain any precursors or synthetic versions of the hormone testosterone. It uses a blend of natural extracts to support the body functions responsible for the optimal production of the hormone.

The all-natural formula of this t-booster is one of the few things we like about it. The human body usually reacts better to supplements containing natural extracts compared to other harsh chemicals. That’s why natural t-boosters are not linked to issues of testosterone suppression and organ failures which are common with synthetic drugs like prohormones and steroids.

That being said, a natural testosterone booster can only be as good and safe as the ingredients used. So, has Umzu added the right ingredients to this product? We’ll find out, but first:

Who Is Umzu?

Umzu is a US-based manufacturer of dietary supplements. The company takes a holistic approach to address some of the common health problems. They explain that their products are formulated to deal with the root cause of a problem and not its symptoms. The supplements are designed to fix problems by facilitating the body functions behind the problem. This, according to Umzu, should be enough since humans are self-healing organisms.

In a practical way, Testro-x is formulated with compounds that facilitate the release of testosterone from the Leydig cells.

Umzu has only been around since 2015, but they have an extensive product inventory. Besides the testosterone booster, they also have supplements for digestion, brain performance, stress relief, blood support, thyroid support, metabolism, weight loss, collagen, joint health, etc. Most of their prices are also quite reasonable, plus they have a “U Save Club” that gives members higher savings for each purchase.

Testro-X Ingredients

The supplement contains:

Magnesium (150mg)

Magnesium plays an important role in various body functions, one of which is testosterone production. Magnesium deficiency is linked to diminished testosterone levels. By consuming the mineral through this supplement, you should be able to restore optimal T-levels in as little as a month.

In one trial, two groups of subjects were given 10mg of Magnesium per kg of body weight. One of the groups was taking part in tae kwon do practices while the other was sedentary. A third group was not given any magnesium at all. At the end of the trial, total and free testosterone levels were higher in individuals taking Magnesium than those who didn’t. Additionally, the group involved in tae kwon do practices had higher t-levels than those who didn’t.

What does this mean? Well, while the Magnesium in Testro-X can boost your t-levels, it’ll work even better if you add some training sessions to your regimen.

Zinc (15mg)

Zinc is an essential mineral required by the body to perform functions like sex hormone production, immune response, and the making of DNA and proteins. Sadly, our bodies have no mechanism for making zinc which means we have to supplement it through dieting.

While you may get decent amounts of zinc from food sources, supplements have proven to be the better option, especially if you have a severe zinc deficiency.

At 15mg per serving, this testosterone booster supplies a good amount of the mineral.

Ashwagandha (400mg)

A popular ayurvedic medication known for boosting testosterone production. Some reports claim it supports t-levels by reducing the amount of cortisol in the body.

In addition to increasing testosterone levels, this adaptogen can also boost physical performance and fat loss.

Coleus Forskohlii Rhozime Extract (250mg)

Forskolin is believed to be effective for both fat loss and testosterone production. The extract promotes weight loss by increasing adenylate cyclase and lipase, which stimulate the breakdown of fatty acids.

Glycine (200mg)

Glycine is an amino acid that functions as a neurotransmitter in the body. It’s also used to create proteins that are used for muscle growth and other functions.

The compound improves sleep quality and cognition.

Inositol (200mg)

Inositol is a carbohydrate that regulates key neurotransmitters. It is naturally produced in the body and can also be consumed through foods and dietary supplements.

Inositol is used to boost fertility and reduce anxiety and depression.

Boron (10mg)

Boron supports a healthy balance between testosterone and estrogen. It increases free and total testosterone while reducing the primary female sex hormone, estrogen.

At 10mg, Testro-X has enough Boron to make a significant impact on your t-levels.

L-Theanine (100mg)

This amino acid has no direct impact on your testosterone production, but studies suggest it boost relaxation and sleep quality. It also reduces stress and anxiety. By combating stress, the compound should theoretically create a conducive atmosphere for healthy testosterone production.

L-Leucine (70mg)

Another amino acid that can support your muscle-building efforts. Scientists report L-leucine activates mTORC1 in skeletal muscles to stimulate protein synthesis and muscle growth.

Black Pepper (10mg)

Black pepper is a common ingredient in dietary supplements. It increases the absorption of other compounds used in supplements making sure they are fully utilized before excretion.

Benefits of Testro-X

Based on the above ingredients, Testro-X users should expect the following results:

  • Better hormonal function
  • Increased energy levels
  • High stamina and endurance
  • Better sleep quality
  • Muscle growth
  • Faster recovery
  • Improved sex life

Is Testro-X Safe?

Testro-X uses an all-natural formula containing scientifically-backed ingredients that are expertly dosed. Proper usage of the supplement has not been associated with any medical complications.

Nevertheless, users are encouraged to go through the formula and make sure there are no ingredients they may be allergic to.

Additionally, individuals with preexisting medical conditions should consult a licensed physician before taking the supplement.


Umzu recommends taking three capsules every day before going to bed. Some people use the pills in mini-cycles. This involves taking the capsules for only three or four days per week which may improve the performance of the adaptogens. Others use it for two or three weeks and take a one-week break.

You are free to experiment with these methods to identify one that works best for you. You can also consult a TRT physician for a more accurate dosage guideline.

Testro-X Reviews

Here are some testimonials from real users of the t-booster:

“Great overall experience with TestroX. Can tell a significant increase in *** drive with this product. Increased strength and stamina for daily Crossfit training sessions. Promotes deeper sleep for increased recovery after grueling workouts. Recommend this product.” By Alex H on Umza

“I switched from another supplement to Testro-X and could tell the difference within the first week. Used in conjunction with Redwood, I started waking up with an ******** every morning. Good stuff!” Robert N on Umza

“Since taking these, I have seen incredible differences, including deep, restful sleep for the first time in many years. I didn’t know this could be an added benefit! These are amazing.” By TBIRD 190 on Amazon

“I’ve used an entire month’s supply, and this stuff is NOT life-changing. Do I feel a tingle in my pringle every once in a while? Yes. Does this turn me into the incredible hulk and cause me to lift a car over my head? No.” By Alain M on Amazon

Final Thoughts: Is Testro-X Worth It?

Testro-X has a decent supplement with several testosterone-boosting compounds. The all-natural formula makes it quite safe, and we love the money-back guarantee. However, it’s really hard to sell the product for that price tag. For roughly the same price, we’d recommend a more established product packing tried and tested compounds like DAA, Fenugreek, and Ginseng.
