Diesel Test Hard Core Overview

Diesel Test Hard Core is an herbal testosterone supplement from Get Diesel, a nutritional supplement company that focuses on workout products. With this product, you're supposed to see your mood improve, your workouts get harder and longer, and your sex drive grow to be bigger than before.

This product contains many of the same ingredients that we've seen in other products. In fact, the only thing we've seen setting this product apart from others is its lack of presence, lack of professionalism, and lack of reviews.

Diesel Test Hard Core Claims

Diesel Test Hard Core is an herbal nutritional supplement. What does that mean? It means that each pill consists mostly of extracts from various plants, herbs, and fruits, all of which are supposed to have concrete effects on the body comparable to drugs or medicines. Some come from Chinese and Japanese natural medicine traditions, and others from India, Europe, or the Americas. All together, the ingredients in Diesel Test Hard Core are supposed to help your body increase the amount of testosterone it produces and minimize estrogen. Since testosterone has much to do with fat loss, muscle growth, stamina, and sex drive, all of these parts of your life are supposed to get a boost that you wouldn't have without it. Although anabolic steroids and herbal testosterone-boosters have the same purpose – increase testosterone – boosters like Diesel Test are supposed to be more natural and safe, since they don't introduce anything new to the body, only help the body make more hormones itself.

Who is Get Diesel, the company behind this product? There's not much information out there. Despite there being references and links to their main website, the actual address seems to be defunct and blank. No, the only information we could find about them was through their Facebook page. While it's nice that they have someplace to hang their hat online and give us an idea of who they are, it's not a very informative page, and their lack of a real website betrays a lack of professionalism and makes them look like amateurs.

Since there's no real detailed source of information about them, we don't know who exactly these people are, or if they're qualified to be selling nutritional products – or even owning a business, period.

The only way to buy this product “directly” from the company is via another website owned by the same guy who runs Get Diesel, a website called FeFiFo. They don't take products back when they've been opened, which is a huge problem – after all, how can you know if you don't like a product until after you've tried it? That leaves you only being able to return unopened items, within 30 days, although they deduct 5% from the transaction (presumably for a re-stock fee).

What does that mean? That means they do not guarantee satisfaction. Otherwise, they would gladly accept open bottles of product that people determine didn't work for them. As of now, if you bought one bottle of Diesel Test from them and it didn't work for you, you'd be out of luck: even if it doesn't work, you get no refund.

Diesel Test Hard Core Ingredients

Diesel Test Hard Core contains a huge list of mainly plant-based ingredients. Here are some of the primary active ones:

  • Epimedium
  • Cayenne
  • Asian Ginseng
  • Tongkat Ali
  • Schizandra
  • “Chonese” Dodderseed
  • Knotweed
  • Diindilomethane

Epimedium and tongkat ali are common aphrodisiacs in Eastern herbal medicine traditions, prescribed for men and women who have trouble getting “in the mood.” Epimedium is even called “horny goat weed,” and for good reason.

Diindilomethane is a compound found in some cruciferous vegetables, and is sometimes used in testosterone supplements to prevent production of estrogen. The idea is that with lower amounts of estrogen in the system, testosterone won't have much to compete, making testosterone more prevalent. But does it work that way? We'll cover that soon.

Schizandra is a plant used primarily in traditional Chinese medicine for increasing energy output, as well as endurance and stamina. Unfortunately it comes with some side effects which could include:

  • Gastrointestinal pain, appetite loss, and heartburn.

“Chonese” dodderseed (it's actually “Chinese”) is an herb used in traditional Chinese medicine used as a “tonic” for general well-being. But as you'll see, this ingredient has no real purpose being in this supplement, and for good reason.

Knotweed is used for a number of symptoms and has been used to treat water retention, coughs, and skin diseases, since it's claimed to be an anti-bacterial.

This Top 10 list has our picks for the best male vitality supplements.

The Science Behind Diesel Test Hard Core

There's a lot of problems with some of the ingredients in this supplement.

Diindilomethane, for exmaple, is in other testosterone supplements, and they all claim the same thing: it helps testosterone levels by reducing estrogen. Where's the evidence? The only study we found was at the National Institutes of Health, where diindilomethane (in indole-3-carbinol) was tested for its ability to reduce peanut allergy symptoms in mice (NIH). That's it. Nothing about estrogen.

Schizandra is pretty problematic, because like many Chinese herbs, there's not enough evidence that it works, and it comes with some side effects like itching, stomach pain, and heartburn (WebMD).

Dodderseed, also a Chinese herb, has very little science supporting the idea that it works, but one thing we noticed that really makes us question why it's in this product in the first place is another of its claimed effects: as a laxative (WebMD, Examine). Why would they include something intended as a laxative in a supplement designed to increase testosterone? We have no idea, and unless people are interested in possibly having to go to the restroom halfway through their workout, they might not be very happy with this supplement.

Here are the best men's supplements for more stamina, more confidence, and more sexual prowess.

Word on the Street about Diesel Test Hard Core

Since there's no main website to look at for Diesel Test Hard Core's customer reviews, we referred to Amazon, where it's sold via the Get Diesel account. Reviews, unfortunately, are mostly negative:

“This is an incredible, natural testosterone-booster, and I've always noticed improvements in my workouts and my mood when taking it. Thanks, Chuck Diesel!” (Notice how it sounds like an advertisement? We wonder how legit this review is.)

“This product isn't as effective as the original.”

“Honestly, this product doesn't work very well. I don't notice much of a difference while taking it.”

“Fantastic. The best testosterone booster I've ever used!”

“I got a bottle that malfunctioned, and they offered to give me a replacement – but I was never sent one! Terrible customer service!”

“This doesn't work.”

“I saw no change in my testosterone levels after using this.”

And on top of all of that, there are only 16 reviews on the Amazon page – 16! Surely if this product we worth checking out, it would have more people buying and reviewing it, but so far, it looks like almost no one has even tried this, and if they've tried it, they definitely weren't impressed enough to write a decent review of it.

Is Diesel Test Hard Core Worth a Try?

So what have we learned? The company that makes this product, Get Diesel, has no website, only a Facebook page that contains no information about who they are. They also have no BBB profile, so there's no way to check up on their customer service history. There's no company return policy that we can read, so there's no guarantee that you'll get treated well if something goes wrong or you're not happy with the product. The supplement itself has a huge number of ingredients, but many of them have no evidence that they work, and some come with some uncomfortable side effects if you're not careful enough.

But worst of all, there are almost no customer reviews of the supplement itself, and the few that there are are largely negative, with people complaining that it doesn't work and that the company's customer service is terrible.

What would we suggest? Keep looking. There are other supplements out there that are far more trustworthy, and run by more professional companies with more transparency and accountability.

Diesel Test Hard Core vs Activate Xtreme

Both of these products are based on increasing testosterone in the body, and both do so through similar ways – they both contain herbal extracts and vitamins that are supposed to help the body's natural testosterone-producing ability. They're about the same price, too, at $42.95 and $44.99 respectively. Activate Xtreme has its own website, which puts it slightly ahead of Diesel Test in terms of their image. You can't find Activate Xtreme on Amazon, it looks like, but you can find it on other nutritional supplement e-stores like Elite Nutrition and Supplements Geeks. You also get slightly more tablets with Diesel Test, with each bottle containing 128, versus Activate Xtreme's 120.
