What Is RexaDrene?

Published on: May 7, 2017

RexaDrene is a male enhancement supplement that claims to be able to increase the size of your penis, as well as increase your stamina in the bedroom in the process. The product claims to provide these benefits using a proprietary blend of ingredients that are claimed to be clinically tested.

The company behind the supplement, Cybex Biotech, doesn’t have much publically available information, but it looks as though they’ve been around for a while. As of the time of this writing, there doesn’t appear to be any current legal disputes filed against the company, nor RexaDrene itself.

Let’s just talk for a moment. Clearly, you don’t have to look very far online or offline to see that many men grapple with inadequacy and the perception that others have on the size of their penis. This very real issue has been turned into a sort of joke in today’s society, and many different factors (such as the rise of pornography and its exaggerated standards for penis size) have served to make the issue more tangible for millions of men around the world.

It stands to reason, then, that a pill claiming to offer a surefire way to achieve a larger, more impressive penis would be a huge boon to men from all corners of the globe who suffer from performance anxiety and other issues relating to penis size.

The question, of course, centers around whether or not this supplement can actually deliver on the claims made by the manufacturer. If not, this supplement has the potential to do more harm than good for many who believe their troubles can potentially be fixed by a pill. In this next section, let’s break down exactly how this pill claims to work inside the body.

How Does RexaDrene Claim To Work?

RexaDrene’s main website warns us that unless we have a chemistry degree, we likely won’t understand how the product works. Despite this, the company says that in short, the pill works by increasing the amount of blood supplied to your corpora cavernosa, which are the chambers that fill with blood to achieve an erection.

According to WebMD, the penis has two of these larger chambers, as well as one smaller chamber which carries urine and ejaculate. By “going to work” on these chambers, the manufacturer claims to be able to increase the overall width, length and hardness of the penis, as well as adding additional sensitivity to the region in the process.

So, in order to answer a fundamental question about RexaDrene, we first need to ask one: can a pill really increase the size of your penis?

Can A Pill Really Make My Penis Larger?

In short, the answer is: not likely. According to this article by WebMd, there isn’t currently any ingredient or combination of ingredients that can actually increase the base size of a man's penis. There are a number of other alternatives to pills, such as surgeries and implants, but those have proven to be very inconsistent with their results on the whole.

Keeping the above in mind, there is still the possibility that RexaDrene would be able to slightly increase the perception of size in an erect penis, likely by increasing and maximizing the amount of blood that floods into the corpora cavernosa during an erection.

This means that in some instances, men have difficulty achieving a “full” erection, and that taking RexaDrene might possibly “fill out” the dimensions of the penis, causing a perceived growth in size as a result.

In order to evaluate if this is really the case, however, we will need to take a look at the ingredients listed within RexaDrene, cross-referencing them to the established scientific data to see how the supplement stacks up to what we know about male enhancement.

What Ingredients Are Used In RexaDrene?

According to the products website, RexaDrene uses a combination of 5 different ingredients in its proprietary formula. These ingredients include Tribulus Terrestris, L-Citrulline, Long Jack, Arginine/ Alpha-Ketoglutarate, and Tribulus Aquaticus. In order to better understand the function of each of these ingredients, let’s break them down one by one below.

Tribulus Terrestris

WebMD lists Tribulus as a plant that produces a spine-covered fruit. The site states that the ingredient has been used in the past to treat Erectile Dysfunction, but claims that there is insufficient clinical evidence to support this use. Additionally, there is no mention of this ingredient being useful for increasing male base penis size.


L-citrulline is a naturally occurring amino acid that is also produced by the human body. It can be found in fruits such as watermelon, and has been used for a wide array of health problems in the past.

There is some evidence according to WebMD that the amino acid improves blood flow throughout the body by opening up veins and arteries, but there is no evidence listed supporting the manufacturers claims that it opens up the two chambers located in your penis directly.

Long Jack

Otherwise known as Eurycoma longifolia, this evergreen shrub is said to have been used for many years in Southeast Asia for enhancing sexula virility. WebMD shows us that there is insufficient evidence present to support any benefit this plant may have for erectile dysfunction, and again says nothing about increasing the size of the penis.


This appears to be two separate ingredients. WebMD states that L-arginine actually might possibly be effective for treating erectile dysfunction, showing that taking 5 grams of the substance can improve sexual function in healthy men. The second substance, however, showed no listed uses in treating erectile health.

Tribulus Aquaticus

According to an article on Livestrong.com, this aquatic plant belongs to the same family as the ingredient listed above, Tribulus Terrestris. While the site lists several uses for the substance, treating male erectile function wasn’t one of them. It also doesn’t appear to have any evidence supporting the claim made by the manufacturer that the substance can help increase production of free testosterone.

Now that we’ve broken down each of the ingredients used in RexaDrene, we need to look at any potential side effects that might come along with taking the supplement.

Potential RexaDrene Side Effects

According to WebMD’s info on the ingredients listed above, some possible side effects that might crop up from taking RexaDrene include abdominal pain, bloating, diarrhea, gout, blood abnormalities, allergies, airway inflammation, worsening of asthma, and low blood pressure.

That being said, because we don’t know what amount of each ingredient is used in the pill's formula, we can’t say for certain how likely you are to encounter these, if at all.

In general, you should always check with your doctor first before beginning to take a supplement that can effect a vital part of your body.

RexaDrene Pricing & Return Policy

Currently, the male enhancement pill is only available by phone and by the main website for the product itself. The pricing structure is laid out as follows:

  • Single bottle (1 month supply) - $39.95
  • Three bottles (3 month supply) - $79.95
  • Five bottles (5 month supply) - $119.95
  • Seven bottles (7 month supply) - $159.95

There doesn’t appear to be any sort of autoship program or any other hidden fees associated with the purchase, and the company offers a 90 day full money-back guarantee.

It looks as though the only way to contact the company to file a return is via the online contact form found on the products main website, so keep this in mind if you are trying to return the product.

The Bottom Line: Will RexaDrene Really Work?

Bringing everything that we’ve learned about RexaDrene together, the answer to this question is not as simple as it at first may seem. It’s important to tackle one of the main claims made by the company; that this pill will make your penis larger. According to WebMd, there is currently no known ingredients that can actually increase the base size of a penis.

There is also not enough evidence from authoritative sources supporting the manufacturers claim that RexaDrene will increase your stamina and sensitivity in the bedroom.

We were able to draw this conclusion by looking directly at the ingredients used in this pill, acknowledging that none of them had any medical data to back up the claims made by the manufacturer.

This being said, some of the ingredients listed within the product have shown positive clinical evidence towards increasing blood flow and helping treat erectile dysfunction in otherwise healthy men.

This lends some credence to the theory that some men taking RexaDrene might indeed notice a perceived improvement in the size of their penises when erect, if only by helping an erection reach its full capacity. That’s one thing, but expecting your penis to actually physically grow to a larger size is another matter entirely.

Having said that, at HighYa we always recommend talking to a qualified professional before purchasing a product such as this online. Seeing is it is highly unlikely this supplement will actually increase the base size of your penis, and that it’s main potential benefit potentially looks to be treating erectile dysfunction, we feel that a better option might be to talk to your doctor about dedicated treatment options for this very real and serious condition.

    RexaDrene does NOT work

    • Morgantown, WV,
    • May 10, 2019
    • Verified Reviewer

    I took RexaDrene as directed for almost 1.5 years and I received zero results. I tried to contact their support several times and they were no help. In fact, they ridiculed and mocked me and refused any help once they did respond. They basically laughed in my face and told me "best of luck".

    I feel the product is a complete lie, sham, and a rip off and I really hope they lose their shirts.

    Bottom Line: No, I would not recommend this to a friend

    I highly recommend RexaDrene

    The guys at RexaDrene have your back, and don't forget they have a killer male enhancement formula where you are going to see results right away. Like I was saying before, they really go the extra mile to make sure every order has a happy customer on the receiving end of it. I had my package stolen from my front door and the people over there at RexaDrene shipped out a replacement order right away.

    Bottom Line: No, I would not recommend this to a friend

    Didn't do anything at all!

    I had bought this product back in March of this year. I decided against myself to get a one-month supply, so I ended up getting the three-month supply instead. I had read the guarantee that if they product did not work, return it within 90 days. Well, it didn't work. I even read and followed the instructions. So unless you have $130 laying around to blow on something unless, do not buy this product!

    Bottom Line: No, I would not recommend this to a friend
