About Crevalor

Crevalor is a powerful thermogenic supplement that enhances performance and stamina, gives you more explosive workouts, and boosts confidence and sexual drive. How?

By featuring a blend of natural, science-backed ingredients that will optimize your free testosterone levels and increase blood flow where it counts. In fact, the manufacturer claims that Crevalor can help “you gain 35% more muscle mass”!

One pill that can make you look and feel like a “real” man? Where do you sign up, right?

Sorry to burst your bubble, but we want to make sure your hard-earned money is well spent. So we think you’ll just be throwing it out the window with Crevalor. To explain why, let’s start with two things: thermogenics and testosterone.

What Is a Thermogenic? Will It Help You Lose Weight?

Thermogenic simply means “to produce heat,” so when it comes to thermogenic supplements like Crevalor, they’re intended to increase your body temperature. And as the thought process goes, if your body temperature is increased, so is your metabolism, thereby helping you lose more weight than diet and exercise alone. Do they work?

This ultimately depends on what you mean by “work.” Yes, there are some clinical studies showing that thermogenic supplements can improve weight loss (see here for a short, but useful, list). But it’s far from a scientific fact.

And even in the studies that reflected positive results, they were modest at best. For example, one study showed that men only burned an extra 100 calories per day when using thermogenics, while another showed that participants only lost an extra 1.3 pounds over the course of a month. From a muscle gain perspective, participants only gained an extra 3.3 pounds of muscle mass over the course of 10 weeks.

What does all of this mean? While we’ll talk more about ingredients shortly, it’s technically possible that Crevalor’s thermogenic properties could help you burn extra fat and gain extra muscle, but the results will almost certainly be less revolutionary than we’re led to believe.

What is Testosterone? Can It Be Increased?

Testosterone is a sex hormone produced by the pituitary gland, which is responsible for a variety of things commonly associated with “manliness,” including growth of the penis and testes, body hair, a deep voice, big, strong muscles, and height.

Up until about the age of 30, most men produce plenty of testosterone to keep their muscles ripped and their libido strong. Once we reach this age, however, testosterone production begins to decrease about 1% per year, leading to side effects like reduced sexual desire, erectile dysfunction, low self-confidence, increased body fat, less muscle bulk and strength, and more. Can anything be done about this?

First, it’s important to distinguish between free and bound testosterone. Most of the testosterone in a man’s body is bound to another sex hormone known as sex hormone-binding globulin (SHBG). If it’s not, the testosterone is known as “free,” which is the only type that’s biologically active (i.e. that can be used by your body to increase muscle mass, etc.). This is why supplements like Crevalor claim to increase the levels of free testosterone in your body.

But there’s insufficient evidence showing that a nutritional supplement can increase free testosterone. Instead, WebMD recommends getting plenty of sleep, keeping active and maintaining a healthy weight, reducing stress, and carefully monitoring your medications.

Alright, in general, we’ve learned that supplements will probably only provide mild fitness benefits, but not any boost in testosterone levels. But what about Crevalor’s ingredients specifically?

Is Crevalor’s Ingredients “Backed By Science”?

We don’t know exactly how much of each ingredient it contains (we’ll come back to this in a second), but Crevalor claims to feature l-arginine, maca root, horny goat weed, tribulus terrestris, and yohimbe.

L-arginine is converted into nitric oxide inside your body, which is a chemical that’s known to widen blood vessels and increase blood flow. As such, it’s listed as “possibly effective” for improving symptoms of erectile dysfunction.

Maca may be effective for improving sexual desire in men, and the active ingredient in yohimbe (known as yohimbine) is thought to be effective for improving impotence.

But even though these might provide some benefits, we have no way of knowing if Crevalor contains enough. For example, you’ll need 5g of l-arginine, 1,500 to 3,000mg of maca, and 15-30mg of yohimbe per day in order to experience any positive effects.

Are These Ingredients Safe?

Although they might not provide you with the “mind-blowing” results claimed by Crevalor’s manufacturer, most of the supplement’s ingredients should be safe, with mild digestive upset as the most common side effect.

However, there are two important things to remember. First, some ingredients (such as tribulus) are fairly new, and long-term safety hasn’t yet been established.

Second, remember how we talked about the lack of a product label before? Well, in addition to what we’ve already discussed, this also means that we don’t know if Crevalor contains yohimbe (the plant material) or just yohimbine (the active ingredient). This is an important distinction, because according to WebMD, “Yohimbe, taken by mouth, is POSSIBLY UNSAFE. Yohimbe has been linked to reports of severe side effects including irregular or rapid heart beat, kidney failure, seizure, heart attack, and others.”

How much will you pay for these ingredients?

The Trap: Crevalor’s “Free” Trial

Despite the fact that Crevalor probably won’t provide the results you’re after (a common theme among nutritional supplements), Crevalor’s free trial—in our opinion—is the biggest red flag that it should be avoided. Why?

First, you might be enticed by the fact that you only have to pay $4.95 to obtain a bottle of Crevalor. But this is how they trap you.

Buried in the fine print or in the Terms, what you might not realize is that 14 days after you place your order (which might take a week or more to receive), you’ll be charged the full price of $89.99! Then, the company will keep the money rolling by sending you a new bottle once every 30 days, and charging your card $89.99 each time.

Now, you might think that you can rely on the Crevalor’s 30-day refund policy if you’re not satisfied, but we think the company will make it as difficult as possible to cancel your trial, end your autoship enrollment, or request a refund.

But here’s the catch: According to Crevalor’s Terms, refunds are only available for unopened product, less S&H charges and a $19.95 restocking fee. But in order to be eligible, you have to agree to “try the product and evaluate its performance before requesting a refund or cancellation.”

So, if you opened the product, you’re not eligible for a refund. But you’re also not eligible if you didn’t try it, literally making it impossible to get your money back.

But don’t take our word for it. Let’s find out what customers have to say for products like Crevalor.

Crevalor’s Competition

Here at HighYa, we’ve reviewed dozens of testosterone boosters like Crevalor (and even wrote an in-depth t-booster buyers guide), including Alpha Limit and Spartagen XT, as well as thermogenic weight loss supplements like Aptulux and Instant Knockout.

And in general, customer feedback isn’t good, averaging just 2 stars (read: be very careful). While many customers complained that these supplements didn’t work, most seemed to reference poor customer service when trying to cancel a trial or autoship program or request a refund.

In numerous instances, customers claimed to have been yelled at, made to believe everything was their fault, and were even purposefully disconnected. Some decided to stop dealing with the company altogether, instead working with their credit card to dispute the charges. Ultimately, we think you’ll experience much of the same with Crevalor.

Our Recommendation? Stay Away From Crevalor

Ok, we’ve covered a lot of ground, so let’s quickly recap what we learned about Crevalor:

  • Many of the supplement’s ingredients won’t work. And even for those that might, there’s probably not enough contained inside to make much of a difference.
  • On top of this, it’s impossible to boost free testosterone levels through supplementation.
  • The product is only sold through a free trial and autoship program, which alone is enough for us to recommend staying away from it.
  • Online customer reviews for products like Crevalor are almost always bad.

As if this wasn’t enough, Crevalor features a quote on their site from MMA star Randy Couture, stating: “I gained an extra 8 pounds of muscle thanks to Crevalor while preparing for the Expendables 3 movie.” However, there’s no third-party evidence online showing that Randy endorses Crevalor, or that he’s even heard of the product. In our opinion, this is a fake celebrity endorsement only intended mislead.

Instead of ordering Crevalor, we’d recommend talking with your doctor if you’re experiencing erectile dysfunction, lack of sex drive, or any other symptoms of low testosterone. After getting you on a treatment plan, we think this will provide much more value for your hard-earned money.
