Hunter Burn vs. Instant Knockout: About The Supplements

When looking for a fat-burning supplement, there are several things you want to consider before making a purchase. For example, you want to make sure they use all-natural ingredients, the proper nutrient forms, the right dosages, and that it’s manufactured in a GMP-certified facility.

Of all the fat burners on the market today, two of the most popular ones are Hunter Burn and Instant Knockout. If either of these two supplements have piqued your interest and you want to figure out which one is best for you, you’ve come to the right place. Let’s learn more about them!

What is Hunter Burn?

Hunter Burn Supplement

Hunter Burn is a fat-burning supplement that’s brought to you by ROAR Ambition — the same company that brings you Instant Knockout and Hourglass Fit. They’re a reputable company that also offers testosterone supplements (Hunter Test, Testofuel) and nootropics (Hunter Focus). 

The Hunter Burn formula is designed to work with your body and diet — not against it — to help you burn fat without losing muscle. It features six science-backed, natural ingredients at clinical doses and doesn’t contain any artificial flavors, colors, gluten, soy, GMO, or preservatives. 

The ingredients are grouped into 3 categories — Hunger Neutralizer, Thermo-Burn, and Energy Unlock. Konjac Root and White Kidney Bean suppress hunger, cayenne pepper and matcha green tea promote thermogenesis, and Vitamin D and L-theanine increase energy levels. 

What is Instant Knockout?

Instant Knockout Supplement

Instant Knockout is another weight loss supplement that’s brought to you by the same company — ROAR Ambition. Much like Hunter Burn, it’s manufactured in a GMP-certified facility and to the best FDA standards, ensuring a safe, quality, and effective formula with real results. 

The formula is designed to help you cut down weight, increase your metabolism, promote thermogenesis, suppress appetite, and manage your weight. It was made for the pros and used by the pros, but now it’s available to anyone looking for an effective weight loss supplement. 

The ingredients can be categorized into three major groups — appetite control, thermogenic boost, and energy boost. The nine ingredients include glucomannan, caffeine, green tea, black pepper extract, cayenne pepper, L-theanine, Vitamin B6, Vitamin B12, and Vitamin D3.

Hunter Burn vs. Instant Knockout: Which Supplement is Better?

Overall, both supplements are quality options for anyone in need of a safe, natural, and effective fat-burning supplement. They’re both manufactured by the same, reputable company and they both utilize a lot of the most prominent ingredients in the weight loss supplement market today. 

With that said, they’re designed for two completely different people. Most importantly, Hunter Burn doesn’t contain a direct source of caffeine, while Instant Knockout does. If you want to increase energy levels and enhance athletic performance, Instant Knockout is the better option. 

Hunter Burn, on the other hand, is a low-stimulant formula that focuses more on curbing those cravings, suppressing your appetite, and increasing your metabolism. If that’s what you’re looking for, Hunter Burn is the better option — despite it being a little more expensive. 

Two quality supplements, two quality options. If your workouts can use a boost, go with Instant Knockout. If you’re trying to eat less and increase metabolism, go with Hunter Burn.
