Sizegenix Review: Does It Really Work For Male?

You are not alone if you are having difficulty conceiving a child. According to a Mayo Clinic article on Healthy Sperm, one out of every seven couples is infertile. 

Male infertility can be caused by a variety of factors, including abnormal function, blockages, low sperm count, and complications during the delivery process, among others.

It’s fortunate that men can address these issues by making a few lifestyle changes. These lifestyle changes include a healthier diet, the elimination of bad habits, and increased energy.

They can also look for non-prescription supplements to help with these issues. Sizegenix is one of these supplements, and the majority of its constituents have clinical evidence that they can improve sperm count, functionality, and quality.

Without further ado, let’s find out in this Sizegenix comprehensive review.

What is Sizegenix?

Sizegenix is another male enhancement supplement designed to provide a surge of nitric oxide in your penis tissue to promote its growth and strength. 

They name their secret delivery is known as Nitric Oxide Surge Wave Technology. However, the supplement is based on a proprietary blend which is a red flag in itself. 

Sizegenix is mainly promoted for three purposes which include size, performance, and pleasure. 

When you see through the Sizegenix review, you’ll find that the opinion of people regarding it is completely mixed. This means the number of people satisfied and dissatisfied is almost equal. 

Still, the supplement claims that it is clinically tested and all-natural. However, we were unable to find any evidence or clinical test for the supplement. 

Sizegenix Manufacturer

On its product page on Amazon, it mentions that Sizegenix is a product by Incredible Health Decisions. The official website of Sizegenix doesn’t seem legit and trustworthy.

The website contains a few absurd pictures for the product promotion. They claim to be the only product on the market that can actually make your penis bigger and stronger.

Sizegenix says that their male enhancement supplement is not only raved by adult film stars but also by many athletes, singers, and business persons. These things sound too big to trust. 

However, their business doesn’t have a BBB page, and thus no data on business accreditation and customer satisfaction rating is found. 

Ingredients Evaluation

Sizegenix male enhancement is made using blending several ingredients in the form of a proprietary blend. 

Even though we don’t have any information about the dosage of ingredients except niacin, the other ingredients can still have some benefits.

There are also 

Here’s an overview of ingredients in Sizegenix

  • Niacin (Vitamin B3): 45mg

Sizegenix Proprietary Complex (Proprietary Blend): 1577mg 

  • Butea Superba
  • Tribulus Terrestris Extract
  • L-Arginine Nitrate
  • Vitis Vinifera
  • Protodexx Matrix Complex
  • L- Citrulline

Niacin (Vitamin B3)

Niacin, also known as Vitamin B3, is a water-soluble B vitamin (essential vitamin) that helps your body convert energy from food into ATP.

It can lower your cholesterol by increasing good HDL while decreasing bad LDL, and thus raising HDL levels can increase nitric oxide production.

There have been animal studies that suggest niacin can help boost testosterone levels, but no human studies have been conducted. Another study found that it can effectively help men with mild ED.

Proprietary Complex

The proprietary blend in the Sizegenix is called the Proprietary Complex, which contains Butea Superba, Tribulus Terrestris Extract, L-Arginine Nitrate, Vitis Vinifera, Protodexx Matrix Complex, L- Citrulline, and four more ingredients.

The label says each serving contains 1577mg of this complex but does not list the specific amounts of each ingredient.

Butea Superba

Butea Superba is an aphrodisiac plant, which means it stimulates sexual instinct, induces veneral desire, and boosts pleasure and performance (1). It is used to treat ED and increase sexual desire, but there is no good scientific evidence to back up these claims.

Because Butea Superba (Red Kwao Krua), a Thai medicine herb, is sometimes considered to be the male counterpart of Pueraria Mirifica, a phytoestrogen known as White Kwao Krua, 

The phytoestrogens found in such high concentrations within the herb can aid in boosting strength, energy, and accelerating recovery times because they mimic male hormones (2).

According to one clinical trial, Butea Superba appears to improve erectile function in ED patients without obvious toxicity and can be used as an alternative herbal remedy for erectile dysfunction.

A small animal study on the effects of long-term treatment with Butea Superba extract on sperm motility and concentration discovered that.

It significantly increased sperm concentration and delayed the decrease in motility with time, with no evidence of sperm anomalies or testicular damage.

Tribulus Terrestris Extract

This is a common ingredient in male enhancement supplements and testosterone boosters. It has also been used in ancient medicine.

Numerous studies have shown that it can increase testosterone and, in turn, improve sperm count, viability, and motility.

Similarly, several studies have discovered a link between Tribulus supplementation and increased libido. Furthermore, studies have revealed that it does not affect testosterone levels or erectile dysfunction.

A recent study called into question its mechanism of action, but it appears to be safe and effective.

L-Arginine Nitrate

L-Arginine, an amino acid necessary for your body to produce nitric oxide, is also a component of Sizegenix.

Lower Nitric oxide levels in the body have been linked to (ED) erectile dysfunction (3).

According to the Mayoclinic, taking oral L-Arginine may improve sexual function in men with ED caused by a physical cause. A recent 2019 review suggests that L-Arginine significantly improves erectile dysfunction when compared to a placebo or no treatment.

An Iraqi study looked at the effect of L-Arginine on sperm parameters in the treatment of infertile men and discovered that it helps in doubling motility and nearly doubling total sperm count.

L-Citrulline in Sizegenix is an amino acid that the body produces. It is transformed by the body into L-arginine, another kind of amino acid necessary for the synthesis of nitric oxide.

And erectile dysfunction is associated with low nitric oxide levels (ED). 

Some evidence suggests that taking L-citrulline supplements can help with mild ED symptoms, particularly in men but additional research is needed to confirm this link.

Vitis Vinifera

Vitis Vinifera, also known as the grapevine, is a flowering plant native to southern Europe and western Asia that is now cultivated worldwide.

There is limited evidence that Vitis Vinifera can boost sperm count.

Some research has linked Vitis Vinifera to improved sexual performance in men when compared to a placebo. According to one animal study, this extract affects some fertility parameters and reduces spermatogenesis in rats.

Another animal study concluded that the effect of Vitis vinifera L. juice on adult male rats’ fertility could be reduced.

There are also some conflicts of interest for Vitis Vinifera when looking at some of the animal studies.

Vitis Vinifera supplementation and improved spermatogenesis in humans requires further study to make a more conclusive connection.

Sizegenix Benefits

Due to the variety of ingredients present in Sizegenix, some of you might be able to notice a few Sizegenix benefits as proposed or claimed by the company. 

However, we are concerned about the thing that for most of you Sizegenix may not work. So, do not have very high expectations until you try. 

The benefits of Sizegenix as claimed by the company includes: 

  1. Increased size of your penis
  2. Enhanced bedroom performance
  3. Pleasure enhancement due to improved penis size
  4. Increase in testosterone levels by almost 74%

The benefits are a result of the Nitro Oxide Wave Surge technology. But, we are not sure if most of you will notice any one of the mentioned benefits.

How does Sizegenix Work?

Sizegenix explains that their supplement works by promoting nitric oxide surge in your body. The main functioning is supported by L-Arginine since it is known for producing Nitric oxide. 

The nitric oxide creates enough space in the two chambers of your penis to let the flow of herbal ingredients into the chambers.

Sizegenix also mentions while most formulas have a delivery rate of 15-28%, it has an 87% deliverability rate. This enables the male enhancement to hit their ingredients with maximum effectiveness.

Also, Sigezenix uses Butea Superba, Tribulus Terrestris, and Long Jack of high quality forming the cornerstone herbal compound of the formula. 

The formula can also lead to an increase in the level of free testosterone which can saturate the inner penis tissue and cause expansion of capillaries giving your penis a great shape. 

Possible Side Effects Of Sizegenix

The recommended dosage for Sizegenix is two capsules per day.

Although there are probably no significant risks of adverse side effects associated with taking the ingredients in Sizegenix, knowing the precise amounts of each ingredient in its formulation creates some problems.

Because the Niacin dosages in this supplement are higher than the RDA, it can cause flushing, especially when first starting out. It can also cause minor side effects such as stomach upset and diarrhea (4).

The following are some common symptoms/side effects associated with male enhancement pills, according to Mayoclinic:

  • Indigestion and changes in vision.
  • Reddening of the face.
  • Persistent headaches.
  • Backache.
  • Congestion in the nose.

The Proprietary Complex blend is primarily comprised of herbs and plant extracts, therefore we do not have any significant safety concerns with these ingredients.

Furthermore, the Sizegenix label states that if you suffer from depression or are being treated for conditions such as high blood pressure, kidney, liver, thyroid, or psychiatric diseases, you should not take this supplement.

Always consult your healthcare provider before attempting to try Sizegenix or any other Male Enhancements Supplements.

Sizegenix Review From Users

Out of several users who purchase Sizegenix very few of them were completely satisfied with the product. 

Users basically praised that Sizegenix instead of increasing their penis size was able to bring their size to the fullest. However, the effects were mainly noticed in long term. 

The negative review mostly mentioned that the product doesn’t work for them and the claims made by the company were fake and not sustainable. 

If you want to buy Sizegenix, we think you must look at the negative reviews too since the negative reviews are significantly higher in numbers.

Should You Buy SizeGenix? The Verdict

Sizegenix male enhancement is a proprietary blend-based supplement that might or might not work for everyone. The company doesn’t have very high trust as far as we noticed. 

Coming to the number of users satisfied with the experience Sizegenix provided, it was almost equal to the number of users dissatisfied.

In simple terms, the Sizegenix review didn’t stand out as we expected. So, it’s better to avoid such products instead of risking your money.

Also, unlike most other supplements, Sizegenix doesn’t even have any money-back guarantee policy, which means if you are not satisfied, it’s simply a waste of dollars. 

We might recommend you to look for some better alternatives to Sizegenix that are more trustworthy and has a higher satisfaction rate. 

That was all for the Sizegenix review. Now, we would like to turn to you. What are your thoughts regarding this supplement? Let us know.
