Hyperburn has become a popular fat burner, but is it any good?

We'll break this down in a Spartans review so you know how it works, how to use it and if it's for you or not. 

Understanding Fat Burning Supplements

Fat burning supplements have gained popularity as people seek ways to enhance their weight loss efforts. These supplements claim to boost metabolism, increase fat burning, and accelerate weight loss. However, not all fat burning supplements are created equal. It's crucial to understand the ingredients and mechanisms behind these supplements to assess their effectiveness.

Key Ingredients in Onest Hyperburn

One standout aspect of Hyperburn, compared to other fat-burning supplements on the market, is its unique blend of ingredients. The formula includes a combination of natural extracts and compounds known for their fat-burning properties. Let's take a closer look at some of the key ingredients in Hyperburn and how they promote weight loss.

Green Tea Extract

Green tea extract is a well-known ingredient in the weight loss industry. It contains antioxidants called catechins, which have been proven to increase metabolism and promote fat oxidation. Additionally, green tea extract acts as an appetite suppressant, making it easier to adhere to a calorie-restricted diet.

Garcinia Cambogia

Garcinia Cambogia is a tropical fruit that contains hydroxycitric acid (HCA). This acid inhibits an enzyme called citrate lyase, which plays a significant role in fat production. By blocking this enzyme, Garcinia Cambogia can prevent the accumulation of excess fat and support weight loss.

Caffeine Anhydrous

Caffeine anhydrous is a dehydrated form of caffeine commonly found in fat-burning supplements. It is known for its stimulating properties, providing an energy boost and improving focus. Additionally, caffeine anhydrous can increase metabolism and enhance fat burning.

Does Hyperburn Really Work? A Closer Look at the Science

While the ingredients in Hyperburn sound promising, it's important to examine the scientific evidence supporting its effectiveness. Several studies have investigated the impact of Hyperburn's ingredients on weight loss.

A study published in the Journal of Nutritional Science and Vitaminology found that green tea extract significantly increases fat oxidation during exercise, leading to greater fat loss. Another study published in the Journal of the American Medical Association concluded that Garcinia Cambogia supplementation resulted in modest weight loss.

Furthermore, a review published in the International Journal of Obesity analyzed the effects of caffeine on weight loss and found that it can increase thermogenesis and fat oxidation. These studies suggest that the ingredients in Hyperburn may indeed have a positive impact on weight loss.

Hyperburn Customer Reviews and Testimonials

To gain a better understanding of how Hyperburn works in real-life scenarios, let's take a look at some customer reviews and testimonials. These firsthand experiences can provide valuable insights into the supplement's effectiveness and potential side effects.

One customer, Sarah, shared her experience with Hyperburn, stating, "I've been using Hyperburn for three months now, and I've already lost 15 pounds. It has given me the energy boost I needed to stay motivated during my workouts, and I've noticed a significant decrease in my appetite."

Another customer, John, said, "I was skeptical at first, but after using Hyperburn for a month, I can say that it really works. I've lost 10 pounds without changing my diet or exercise routine. I highly recommend it."

These positive testimonials reflect the potential benefits of Hyperburn and the positive impact it can have on weight loss efforts.

Potential Side Effects of Hyperburn

While Hyperburn is generally well-tolerated, it's important to be aware of any potential side effects. Some users have reported mild side effects such as increased heart rate, jitters, and difficulty sleeping due to the caffeine content in the supplement. It's crucial to start with a lower dosage and monitor your body's response before increasing the intake.

If you have any underlying medical conditions or are taking any medications, it's always a good idea to consult with your healthcare provider before starting any new supplement.

How to Properly Use Hyperburn for Maximum Results


Like any fat burning supplement, the harder we work, the better it works.

This means cleaning up the diet & adding in some movement to get the most out of your supplements. 

We recommend taking Hyperburn 1-2 per day, but starting out at just once.

Mix 1 scoop in 300ml of water and consume first thing in the morning upon rising.

This could also be used as a pre-training supplement to help boost energy and focus. 

Where to Buy Hyperburn and Pricing Options

Hyperburn is available for purchase on the official website. It's essential to buy directly from the manufacturer to ensure you're getting a genuine product and take advantage of any special offers or discounts. The supplement comes in different package options, allowing you to choose the one that best fits your needs and budget.

Conclusion: Is Hyperburn Worth the Hype?


For us here at Spartans, yes! The formula is stacked, dosing in great and there's a big range of flavours to choose from.
