vaso 9

Why buy Vaso-9? According to the official website, it “is guaranteed to increase penis size by an average of 31%.” Not only is that claim bold, it’s very specific. And specific claims are usually generated from user reviews and research.

But that’s not always the case and a lot of marketing departments realize specific numbers can draw visitors in and hook them. Let’s find out if you can really expect to add size and improve your sex life with Vaso 9.

What Do Users Say About Vaso-9?

“We have a 96% success rate,” declares “Most men add between 2” to 5” to the length while some men add even more.”

The site features testimonials from men claiming Vaso-9 made them bigger. But I was concerned because is the most biased information source. The company will say just about anything to sell their product. Some companies even write fake testimonials.

The only way to find the truth is by reading unbiased reviews; not what the biased company says. Unfortunately, I couldn’t find any users reviews online.

Was Vaso-9 Researched?

“Is Vaso-9 clinically proven?” asks the official website, then answers with a resounding yes. So then, where’s the research? “Vaso-9 is backed and supported by numerous double-blind-placebo controlled studies.”

Just because Vaso-9 may contain proven ingredients doesn’t mean the company can say it was clinically proven. There’s a big difference between combining researched ingredients and researching an ingredient combination.

Vaso-9 was not researched and unbiased users reviews are lacking. So, I’m not sure where the company gets their “31% increase in penis size” statistic.

Were the Ingredients Clinically Tested?

To this point, I wasn’t impressed with how well the Vaso-9 company was supporting their claims. So I was relieved to see several ingredient studies listed on the site. Perhaps the claim about researched ingredients would be true…

Unfortunately, the official website doesn’t support every ingredient with research; mostly just tribulus terrestris. So, I found all but 2 of these studies.

Tribulus Terrestris supposedly boosts testosterone levels and libido. But the researchers don’t agree on whether it’s actually effective. One study showed tribulus terrestris improves erections and sexual performance.[1] But 2 studies listed on showed tribulus terrestris does not raise testosterone levels.[2][3]

L-Citrulline converts into L-arginine, which releases nitric oxide and increases blood flow. Although L-arginine is the most common nitric oxide potentiator, L-citrulline may be more effective because it’s more bioavailable. One study showed L-citrulline improves erections in men with mild erectile dysfunction.[4]

L-Arginine Nitrate gets turned in nitric oxide once it enters the blood stream. Nitric oxide widens blood vessels and allows more blood to pass through. When nitric oxide levels decrease, erectile dysfunction may result. In one study, L-arginine nitrate raised nitric oxide levels and enhanced erections.[5]

Eurycoma Longifolia is a well-known aphrodisiac that also increases testosterone. Study participants with hypogonadism saw their testosterone levels increase to normal after taking eurycoma longifolia.[6]

Maca Root is used to heighten libido, improve fertility, and promote testosterone production. However, researchers showed maca root has no impact on testosterone levels.[7] It is rich in nutrients though, and may increase stamina.

Avena Sativa is the fancy name for common oats. Some people believe it enhances sexual desire, performance, and erections. But if there are any studies, I was unable to find them.

Long Pepper has several benefits, but none are related to sexual performance. Typically, people use long pepper to suppress nerve activity, treat muscle spasms, and drive gas from the intestines.

During my research, I didn’t find a single study proving these ingredients increase penis size. In fact, I don’t know any natural ingredients able to produce that result. So, why would the company guarantee Vaso-9 increases penis size when this isn’t even possible?

Safety and Side Effects

In answer to the question — “Are there any negative side effects?” — the Vaso-9 company says “Absolutely zero.” But I wasn’t convinced.

First off, natural ingredients can cause side effects. If huge dosages are used, the risk for side effects increases. The Vaso-9 company doesn’t disclose their dosages, so consumers have no way to see if safe amounts were used.

In addition, the ingredients haven’t been tested enough for researchers to verify they are safe or not.

What’s the Best Time to Take Vaso-9?

You can take Vaso-9 any time — as long as your stomach is empty. Take 2 pills before a meal, 2 hours after a meal, in the morning, during the day, or before bed. Drink a large glass of water when you take Vaso-9.

Vaso-9 is actually pretty affordable; especially when you buy in bulk. The only place to buy online is

Is Vaso-9 Worth Trying?

The company makes many claims about Vaso-9 that aren’t backed by research or unbiased user reviews. The formula may improve sexual performance, erections, and libido. But it cannot cause the penis to grow longer. Even the studies on don’t support the company’s claims about penis enlargement. The claim about “absolutely zero” side effects isn’t supported either.

I’m disappointed in the Vaso-9 company for making so many unsupported claims. And I’m more than a little concerned about the company’s reliability. I don’t recommend buying Vaso-9 because you could probably find a better male enhancement product.

    I tried it for 60 days and gained nothing more than a harder erection. I likely wouldn’t recommend it.
