Master Testo Pro Review - 13 Things You Need to Know

We’re always interested in learning about new supplements made to enhance the lives of the people who take them. This time, our interest was piqued by the buzz around a supplement called Master Testo Pro. It’s a male enhancement supplement that is supposed to “make an enormous difference.”

One thing that we were instantly concerned about was the lack of information about the company behind Master Testo Pro. After that, our research team looked at the scientific evidence behind the ingredients, side effects, and what users are saying about it. Finally, we took all the information the researchers gathered and condensed it to deliver this report that gives you just the information you need to know before trying Master Testo Pro.

What is Master Testo Pro?

Master Testo Pro is a supplement that is used to increase testosterone levels in men. It comes in a capsule form and is taken before a workout to shorten the recovery time after a workout. It is also supposed to improve your workout experience, giving you increased stamina.

In addition to amping up your workout, it’s also supposed to boost your sex life. Supposedly, when you take Master Testo Pro, you’ll also get an increase in sex drive and sexual stamina.

How Did Master Testo Pro Start?

While researching Master Testo Pro, the manufacturer of the product was a major stumbling block for our team. This is one of those supplements that pops up with more than one “official” website but no information about the company itself.

We did find a file for Master Testo Pro on the Better Business Bureau’s (BBB) website. Based on the information found there, the company appears to be based in Huntington Beach, CA. According to the BBB, the business started in September 2017.

Master Testo Pro’s BBB rating is currently a A-. There are two customer complaints listed. Both have to do with unexpected charges after ordering the product.

Beyond that, our researchers were unable to find out anything about the founders of the company. We don’t even know if they follow the Current Good Manufacturing Practices (CGMPs) established by the U.S. Food and Drug Administration (FDA) to ensure product safety.

Although supplements are not regulated by the FDA the way that prescription medications are, the FDA does regulate the quality of supplements. Companies that follow CGMPs usually indicate this on their website and place a seal on their product bottles. In the case of Master Testo Pro, neither of these things are present.


Master Testo Pro Claims

Master Testo Pro claims some amazing results. They say that men who use the product will:

  • Increase testosterone levels
  • Build lean muscle
  • Decrease body fat
  • Increase sex drive

Master Testo Pro Claims

If those claims proved to be true, Master Testo Pro would certainly be a supplement worth investing your money into. Unfortunately, our researchers didn’t find convincing evidence to support the claims. But, we’ll get into that a little later.


Master Testo Pro Ingredients

The Master Testo Pro Websites don’t provide a list of ingredients. Fortunately, you can find images of the product label on the Internet. According to the nutritional label, the Master Testo Pro ingredients are:

  • Tongkat Ali
  • Maca
  • L-Arginine
  • Ginseng Blend

Master Testo Pro ingredients

Tongkat Ali

Tongkat Ali’s scientific name is Eurycoma longifolia. It is also known as Long Jack. It is a plant that mainly grows in Malaysia and Indonesia, though it is found in other parts of Asia as well. Eurycoma is a shrub that produces flowers. The root of the plant is the part that is usually used in medicines and supplements.

In traditional medicine, tongkat ali is used for:

  • Recovery after childbirth
  • Fever
  • Diarrhea
  • Indigestion
  • Jaundice
  • Headaches
  • Stomachaches

There is some scientific evidence that tongkat ali may be useful for improving male sexual function.

A study published in Evidence-Based Complementary and Alternative MedicineeCAM tested a supplement containing tongkat ali on 109 men who were between 30 and 55 years old. The study took place over a 12-week period. Some of the men took 300 mg tongkat ali, and others took a placebo. At the end of the study, the researchers determined that the men who took the supplement saw an improvement in libido. Those who were overweight also lost some fat mass. However, men of normal weight did not see the same effect.

Master Testo Pro ingredients - tongkat ali

Although the results of the study sound impressive, there’s something you should know. The study was funded by the company that makes the supplement used. That means the researchers may have been influenced and had a stake in proving the supplement works.

According to Phytotherapy Research, some studies show that tongkat ali could increase testosterone, but only in men with certain conditions. Men who are infertile might see a small increase in testosterone levels. And, men who are under a great deal of stress may be able to prevent testosterone from dropping. However, tongkat ali does not appear to increase testosterone in men who are healthy.

Tongkat ali has not been shown to improve exercise endurance.


Maca is a kind of plant that grows in Peru. The root of the plant, which is similar to a turnip, is dried and ground into flour used to make foods. It is also used in traditional medicine to treat sexual dysfunction.

Master Testo Pro ingredients - Maca Root

Though it resembles a turnip, the plant is a member of the broccoli family. It has been the subject of numerous studies in Peru, but there has not been much research conducted in other parts of the world. Because maca is a product of Peru, there is some concern that evidence could be manipulated to support the export of the plant.

Maca is most often used in supplements as a sexual enhancer.


L-arginine is an amino acid that is used to create protein. Most people’s bodies make all the l-arginine they need. Additionally, you get some in your diet when you eat high-protein foods like fish, red meat, whole grains, and beans.

Master Testo Pro ingredients - l-arginine

L-arginine is likely included in Master Testo Pro because it causes veins to dilate, allowing blood to flow more easily. As a result, it may help men to get erections.

Some studies do indicate an increase in nitric oxide, but an equal number of studies show that l-arginine does not affect nitric oxide.


Ginseng is made from the roots of several plants in the genus Panax, including:

  • South China Ginseng
  • American Ginseng
  • Korean Ginseng

Master Testo Pro ingredients ginseng

Ginseng has been used in Chinese medicine for hundreds of years. It was used to create a tonic for treating people with chronic health problems. Unfortunately, there’s a lack of clinical evidence showing it is effective for treating any health problem.

Some studies have indicated that ginseng could benefit men with erectile dysfunction. A study published in the British Journal of Clinical Pharmacology showed that supplementation with red ginseng improved psychogenic erectile dysfunction.

Unfortunately, even the researchers involved in the study agree that the number of participants, just 7, was “too low to draw definitive conclusions. Thus more rigorous studies are necessary.”

Ginseng does not appear to affect testosterone levels. According to a study published in the Asian Journal of Andrology, 60 participants were involved in a study to see if Korean ginseng (KRG) would improve symptoms of erectile dysfunction. All 60 of the men involved had mild or moderate erectile dysfunction.

Some of the men took 1,000 mg of KRG three times per day. The rest received a placebo. At the end of the study, testosterone levels “were not statistically significant differences between the KRG and the placebo group.”


Master Testo Pro Benefits and Results

The makers of Master Testo Pro would have you believe the benefits of using their supplement are amazing. They say that you’ll enjoy:

  • Higher testosterone levels
  • More stamina during workouts
  • Increased sex drive
  • Fat loss

The information our researchers found concerning the Master Testo Pro ingredients suggests that some men who have problems achieving erections might see a slight benefit from taking the supplement. They might even get a little boost in sex drive. But, they should not expect to have more testosterone.

As for the supposed benefits for athletes looking for a better workout and bigger, stronger muscles, there isn’t sufficient clinical evidence supporting the use of Master Testo Pro for any athletic benefit.

Master Testo Pro Benefits

Master Testo Pro and Weight Loss

Master Testo Pro is mainly marketed as a male enhancement supplement. However, the makers do say that the product helps men achieve that lean, cut look that many bodybuilders are looking for.

Based on the science behind the ingredients, it does not appear that you can expect to lose any weight as a result of taking Master Testo Pro. Any weight loss you do achieve is likely to be due to other factors, such as burning extra calories through exercise or changing the way you eat.

How to Take Master Testo Pro

One of the Master Testo Pro websites provides some rudimentary information about how to take the supplement, but we were unable to find any detailed instructions. The information our researchers did find says to:

  • Take the capsules before a workout
  • Workout like you normally would
  • Experience a shorter recovery time

We have no idea how many capsules you should take, whether you can or should take them more than once per day, or if they should be taken with food.


Master Testo Pro Price

Unfortunately, we could not find a website or retailer that sold Master Testo Pro, meaning it may not be on the market anymore.

Is the Master Testo Pro Free Trial a Scam?

Possibly. The thing that Master Testo Pro doesn’t make plain on their websites is that when you sign up for their free trial, you must cancel within 14 days or you’ll automatically be signed up for their monthly subscription service. With this service, you’ll be charged $89.95 each month and receive one bottle of Master Testo Pro.

The information about the free trial is only found in the Terms and Conditions for the free trial…at the bottom of the web page.

The Federal Trade Commission (FTC) warns consumers to beware of free trial offers. Before accepting a free trial, they recommend taking the following steps:

  • Learn about the company by researching them on the Internet.
  • Read the terms and conditions.
  • Find out the company behind the offer. The FTC says that when you buy online, the pop up you fill out might be from a different company.
  • Set yourself a reminder to cancel the subscription within the time limit.
  • Check your financial statements for fraudulent charges.

Potential Master Testo Pro Side Effects

There are no side effects mentioned on the Master Testo Pro websites. That doesn’t mean there are none possible, though. While some people might not have any side effects, others could react to the ingredients in Master Testo Pro.

Maca appears to be a fairly safe substance. However, certain people should avoid products containing maca, including:

Pregnant or Breastfeeding Women: Not enough research has been conducted to determine whether maca is safe in this situation.

People with Hormone-Sensitive Conditions: Maca can have some of the same effects as estrogen.

Master Testo Pro side effects

People who have taken ginseng have reported the following side effects:

  • Headaches
  • Nervousness
  • Digestion problems
  • Diarrhea
  • Dizziness
  • Irritability
  • Seizures
  • Slow heartbeat

Possible side effects of l-arginine include:

  • Bloating
  • Diarrhea
  • Gout
  • Pain in the abdomen
  • Inflammation of airways
Side Effects

Master Testo Pro Product Warnings

The Master Testo Pro websites don’t list any warnings about the product.

We would be remiss if we didn’t tell you that you should always talk to a doctor before trying a new supplement. This is especially true if you are taking any medications or if you have a medical condition.

Master Testo Pro Alternatives

There’s certainly no shortage of Master Testo Pro alternatives that are supposed to increase testosterone levels. Some alternative supplements are:

What Users Are Saying

“The company clearly didn’t advertise their ordering policy, nor were they up front about it. They charged me for a product and was not up front about it.”

“I ordered a trial from this company, and was assured that I would only pay shipping for this product. I willingly paid shipping, but 2 weeks later, I was charged over $190. I did not authorize these charges.”

Bottom Line

Bottom Line on Master Testo Pro

In the end, we did find a few things we like about Master Testo Pro. We like that the ingredients are natural and that there’s a slight chance men could see a boost in their libido. However, there are also several things that cause us some concern, such as:

  • There’s a lack of evidence indicating that Master Testo Pro can increase testosterone and improve the workout experience.
  • Accepting the free trial sets customers up for monthly billing at a much higher rate than they’ll pay for the supplement from other retailers like Amazon.
  • Some are some potentially serious side effects associated with some of the ingredients.

Considering there are alternatives to Master Testo Pro; one may think about the benefits of a program that consists of a clinically-proven method of weight loss and offers exceptional customer care.

Among the best weight-loss programs we’ve seen is called Noom. With all the power of human coaching, personalized meal plans and expert and doctor support, you couldn’t ask for more out of a weight-loss app.

Also, the team behind Noom is offering a free trial as a sign of confidence in their program.
