My Findings & Verdict

My Rating


FULL DISCLOSURE – I used to work at Roar Ambition and worked on the updates to Instant Knockout Cut to allow us to incorporate the meal replacement Instant Knockout Complete.

The last set of changes made to the product were based on the latest research on the best ingredients and dosages to keep Instant Knockout Cut as one of the very best fat burners on the market.

It was also tweaked to make the formula suitable for vegans, the capsules being changed from gelatine to a vegetable compound.

I have not only worked on the formulation of Instant Knockout Cut, I have tested and used the product many times so although I worked for Roar Ambition, this review is unbiased and in no was associated with or endorsed by them.

Why you should trust me

Unlike a lot of other companies who only research the ingredients and make a judgement base only on that, I actually try the products I review!

As stated earlier, I used to work on this product so have first hand knowledge of not just the formula, but why each of the ingredients was added to the product.

It’s also important to note that I have tried this product on many occasions, both professionally to test it and personally as a fat burner.

I’ve also spent the time researching ingredients, working through the papers and research reports that show what can and won’t work. I’ve also spent the last 5 years in the supplements business so know a thing or two about ingredients. For more see the about us page.

How I evaluated Instant Knockout Cut

Evaluating a product like Instant Knockout Cut is straightforward. First and foremost I have tried this product myself so I know how it makes me feel and if it does what it is supposed to do.

I have then broken down my evaluation into specific criteria that I believe reflect the information needed by someone looking to buy this product.

Then I have done some additional research to make a confident assessment of a product’s potential.

I have started with ingredients as this is one on the most important parts of my final rating assessment. Provided there’s nothing in there I wouldn’t take myself or at least a suspicion that someone might want to try a given supplement, I move on to try the product myself.

I will only do this if I believe that the product is safe, has safe levels of ingredients and I know what I am putting in my body.

After that I want to see if the product is effective in doing what is claims to do.

The last criteria for my evaluation comprises prices, discounts, subscription service, customer service, and more. These are all less influential in my overall ratings, but they are often the things that can tip the scales for anyone looking to try a supplement for the first time, or anyone who is torn between two products.

Let’s take a closer look at each of these criteria for a clearer picture of whether Instant Knockout Cut is be a good fat burner for you.

Instant Knockout Cut Costs – 4/5

Instant Knockout Cut 3 + 1FREE

Ultimate Cutting Stack – 4 Months

Reviewed By: WhichSupps

My cost consideration is a combination of price, bulk or subscription discounts, return policy, and shipping costs. Most fat burners cost somewhere between £15 and £75. The single pack cost of Instant Knockout Cut at £40.00 price puts it at the mid to higher end of that range. And like most of its competitors, it suggests you bulk purchase to make savings.

One additional bonus for bulk purchases is that Instant Knockout Cut comes with Boss Shred, a workout plan that was designed by the team at Roar to go with this product. Not many other companies can give away programs that are designed by the same team (maybe the same company but Roar is a tight team).

How to take Instant Knockout Cut

One of the things that has always been a little awkward about Instant Knockout Cut is how many times you should take it per day.

The website suggest 1 four times per day, as per this graph:

When To Take Instant Knockout Cut

This would suggest 1 at 8am, then 11am followed by 2pm and then 5pm. Don’t take it before bed time, it has quite a bit of caffeine in it.

By taking four equal doses through-out the main part off the day, you’re burning fat for a longer period of time and you’re absorbing all of each dose.

Instant Knockout Cut Final Thoughts

Instant Knockout Cut is a good product, I know it is because I worked on the update to the formula to include clear vegan capsules, took out the Zinc and Chromium to add in more Glucomannan or Konjac Root, which is recognised as an ingredient that can help manage weight.

I’ve also tried it, but I don’t workout as much as I should so the shredding properties were a little lost on me. Yes you have to do some kind of exercise, these pills don’t work on their own!

The appetite suppressant element of Instant Knockout Cut works, you feel fuller for longer when taking these capsules so you eat less.
