What is it?

ExtenZe is a male enhancement supplement with big promises to improve sexual function and increase penis size by over 25%.

According to the manufacturer, ExtenZe breaks down the nitric oxide present in the body, an important component used to relax blood vessels in order to increase blood flow.

The ExtenZe site states this product is the “number one selling male vitality product.” The manufacturer claims the supplement will help men with lowered levels of testosterone increase strength, stamina and libido.

After taking a look at a number of male enhancement drugs, our review experts have come to the conclusion that Viritenz is the best option out there. Made from a potent, yet natural formula, consumers have consistently given the supplement high reviews, seeing great results without the insidious side effects.

ExtenZe Quality of Ingredients

The ingredients found in ExtenZe are par for the course. Ingredients like tribulus, yohimbe bark, L-arginine are found in a number of male enhancement products. As with many similar products, ExtenZe does not provide an ingredient list with the exact amounts laid out. This makes it a bit challenging to evaluate the quality of the product as a whole.

While most of the active ingredient amounts have not been disclosed, the “less active ingredients” in each pill are as follows:

  • Zinc: 25 mg
  • Folic Acid: 400 mcg
  • Dehydroepiandrosterone (DHEA): 50 mg

As far as safety is concerned, the makers of ExtenZe have stated that there are no adverse side effects associated with taking the supplement. However, there are plenty of accounts by consumers stating the opposite (see below for customer opinions).

We strongly recommend avoiding ExtenZe if you have a high blood pressure, or a history or heart, liver or kidney problems.

While the makers of ExtenZe claim the supplement is side-effect-free, several users have experienced the following after taking the supplement:

  • Heart palpitations
  • Anxiety
  • Shifts in mood
  • Sleeplessness
  • Headaches
  • Allergic reactions

Consumers may want to consider taking a supplement that includes DHEA, as steroids can cause some adverse effects on the user, especially when combined with ingredients like yohimbe that have long been known to cause adverse side effects in users.

If you’re looking for a safer alternative to ExtenZe, here’s our guide to choosing the best male enhancement products.

The Price and Quality of ExtenZe

ExtenZe is priced at the higher end of the male enhancement spectrum, though by no means is it the most expensive. A 30-day supply retails for $59.99, though there are a number of offers. The website offers a 60-day free money back guarantee, and a number of bundling options that bring the price down a bit per unit.

Business of ExtenZe

The company is also known as Biotab Nutraceuticals. Their contact information is listed as follows:

Phone Number: (855) 714-3234

Address: 401 E. Huntington Dr.

Monrovia, CA 91016

Email: [email protected]

ExtenZe has been hit with a number of lawsuits over the course of the past few years. Plaintiffs have cited false claims, shady business practices and a number of adverse side effects as grounds to sue.

Biotab Nutraceuticals does not have a listing with the Better Business Bureau, though the ExtenZe webpage links to a BBB listing that appears to have nothing to do with the supplement, nor Biotab.

If you have concerns about ordering direct from the company, ExtenZe is available at a number of stores; GNC, Rite Aid, Walmart and more.

Customer Opinions of ExtenZe

Customer reviews of ExtenZe have been mixed for the most part, but they do suggest this may not be the most effective solution out there.

Here’s what people are saying:

“After taking the pills according to the directions, I quickly developed flu symtoms.”

“It does seem to get the blood moving, but that’s it.”

“This supplement made me jittery, and gave me a really upset stomach.”

“Used this for a bit, and lost my appetite for the entire time.”

“Used ExteZe for a few weeks with no results. This product is pure marketing.”

Other customers have mentioned they haven’t seen the results that were promised on the website, though a few have mentioned an increase in energy and slight improvements in general physical stamina. Any clinically-backed data proving ExtenZe improves sexual performance remains to be seen.

Conclusion – Does ExtenZe Work?

While some consumers have reported positive effects associated with taking ExtenZe, the cons outweigh the pros by a longshot. Stronger erections and increased sexual performance seen by some consumers are offset by the negative side effects, false marketing claims and bad business practices associated with the manufacturer.

At first glance, ExtenZe appears to have a number of positive side effects — penile growth, stronger erections, improved sexual performance. Ingredients like Yohimbe and L-arginine have long been touted as effective solutions for erectile dysfunction. However, this combination of stimulants, herbs, vasodilators and steroids may compromise your overall health.

There is evidence suggesting that ExtenZe works for some users, however, the adverse effects from loss of appetite to upset stomach and even hives, make it clear that this is supplement is not worth your while. Additionally, any product that claims to increase penis size by x amount is usually guilty of unethical selling practices. For these reasons, we cannot recommend ExtenZe.

Among the many products our reviewers have tested, we’ve found that Viritenz is the best on the market. With its potent formula and all-natural ingredients Viritenz is a healthy alternative to other male enhancement products on the market.

Additionally, Viritenz is manufactured in an FDA approved facility, meaning the everything from the formula to the machinery is subject to regular third-party inspections. To learn more about Viritenz, click here.

I bought extenze a day ago, used it for the first time. Within 20 minutes, my skin had a burning sensation and it was red through out my body, mainly torso and arms. I read online that it would take 8-24 hours for it to go away but within the hour it was completely gone. Should i avoid using this completely? Thanks

Barry says:

That happened to me too. But not right away. It seemed to be working over the course of about 8 or 9 days, And then one morning i took one and 20 minutes later my face got really red and I started flushing, My arms and torso had redness too. I went to ER and they didn’t seemed to alarmed but made me stay for observation for a couple of hours. They gave me Benadryl, and prednizone, and it seemed like it was beggining to clear up anyway, And then i was fine 2 hrs later. Now I’m afraid to take it again. Really freaked me out.
