#2 – Instant Knockout Fat Burner


About Instant Knockout

Instant Knockout is a product from Roar Ambition. This specialist supplements company have used 10 powerful natural fat burning ingredients to come up with this product.

This fat burner not only uses a scientifically backed ingredients profile, but contains a monster 4 capsule serving size. If you purchase a 3 month supply, you get an extra month free too. Which they GUARANTEE gets you results. 

Widely reviewed online and with a large amount of positive testimonials on YouTube, Instant Knockout is in our eyes worth the hype that surrounds it and so takes top spot in our top 3.

While Grenade Thermo Detonator and MusclePhram Shred Sport are both good fat burners, they lack the range of proven ingredients and product quality of Instant Knockout.

2. Grenade Thermo Detonator – Close 2nd, Bigger Dose Required


This is the most high profile fat burner of our top 3. While Grenade has a lot of merits and is widely used, with a little research you’d find yourself looking for something with more proven ingredients in it. One thing we do love about Grenades offering is the brand though. It looks great.

3. Musclepharm Shred Sport


Last in our top 3 is Musclepharm Shred Sport, this fat burner was previously number #1, but just couldn’t better Instant Knockout or Grenade Thermo Detonator.

Shred Sport was a good fat burner that was trialled again recently, but ultimately, to get the better results, you need to be training 4+ times per week and training hard.

This is to make use of the amino acids in the product, such as the Theacrine. Overall, you are going to get better results from our #1 and #2.

Read our full review (5 minutes) or check the summary:

The good:

  • Caffeine, Green tea, Black pepper
  • Affordable price
  • Looks great
  • Trusted company

The bad:

  • Need to be training HARD to make work
  • Amino acids could be dosed higher
  • Serving isn’t spread evenly
  • Some side effects reported due to ingredients interacting.

  1. Jane says

    I have read through several fat burner review lately because I need an active fat burner supplement for my mum. This is just so appealing and I’m glad I found this now; it really brought a great relief to me. I’m sure going to give the Instant Knockout a try. Thanks for the info.

  2. Mia Cole says

    Yeah! I know Instant Knockout so well. It’s one of my ever-trusted supplements for burning fat while I was in service. But now, I have relocated and couldn’t find anywhere to get one again. Thank you for this fat burner review, please how can I get the Instant knock out again?

  3. Cindy Mathew says

    As for me, I prefer the PhysiqueSeries over the Instant knockout for burning fat. Though many fat burner reviews may tell you otherwise. It has this special ingredient included in it that do get me on a good mood every time I take the fat burner supplement. The unusual feelings I do have while taking other fat burner supplements was completely taken off.

  4. Izvorul Ascun says

    I’m surely going to give the Instant Knockout a try. I love the assurance you gave on the ‘money back’ policy. However, I hope it help me burn some fat and lose weight even before the three months you stated so that there will eventually be no need asking for a refund. Thanks.

  5. Rita Matic says

    What irks me about fat burner supplements is the stomach bloating feelings I get from their use. I really want to try this Instant Knockout too and hope the story actually changes this time around.

  6. Gemma says

    If you ask me which is the best of all the fat burner supplements I had taken before, I will tell you it’s the PhysiqueSeries. It was recommended for me by my cousin, Janet. I actually doubted the supplement at first, but it gave an incredible result after few weeks. Am glad I found this product.

    1. Fat Burner James says

      We’re glad you like it Gemma. As with any fat burner you just need to stick at it and keep your diet clean whilst doing some bits of exercise. To work out how best to burn away fat, you need to ensure you are in a calorie deficit. A calorie calculator is a great way of doing this, see one here – http://www.calculator.net/calorie-calculator.html

  7. Rachael Jens says

    What I really need now is a working fat burner supplement that works. I have had enough mouth-washing commercials about many fat burner reviews that eventually turned to be worthless. But I want to ask; can I get 2 of these products and combine their effect? I mean, can I actually use both of them at the same time?

    1. Fat Burner James says

      We wouldn’t recommend it. Just buy one fat burner and follow the instructions. We got the best results from using Instant Knockout.
      Remember to keep your diet clean.

      We don’t do commercials round here, not sure we understand that! Just real fat burner reviews 🙂

    2. Cynthia Patel says

      I really don’t think its right Rachael. I used Instant knockout and it worked well for me. I saw great result after using the first 120 capsules. You can also try it out or you go for the Thermaxin Thermo Enhancer if you are a bit low on cash; it also works well.

  8. Vicky says

    If it involves voting I’d vote for Instant knockout as the best fat burner supplement out there. I love it because it completely takes off the usual side effects that do follow many fat burner supplements. I won’t have to worry myself of sleeplessness because I want to burn fat. It can be so annoying!

    1. Fat Burner James says

      Just make sure you don’t take it too close to bed!

  9. Perpi says

    Just 120 capsules and 4 doses per day? That’s apparently around a month use. You mean I can actually lose this disgusting fat in just a month? I can’t wait to get this fat burner supplement. Or am I missing something?

  10. Rachael Mills says

    Hmm, was thinking of going for transparent labs physique series instead of instant knockout but I can see here that everybody that has used instant knock is giving a good review so I think I will also try it out regardless of the price.

  11. Bia Ali says

    It worked perfectly well for me! I couldn’t believe there could be such a fat burner supplement that works so fast until I tried instant knockout. I thought it was expensive, but it’s really worth the price.

    1. Fat Burner James says

      Lot’s of people think it’s expensive. We are glad our recommendation got you those results though.

  12. Gail Val says

    The Instant knockout fat burner supplement actually worked. But to make sure I get the most out of this supplement, I went farther than what the fat burner review said. I combined exercise (up to 3days in a week) and good diet with it. The result afterwards was totally incredible.

  13. Fareha Linu says

    The rigorous exercises being recommended to me all the time in my quest to burning fat was just something else. I decided to settle for a fat burner supplement. I was lucky at my first pick; I actually got the best fat burner. The PhysiqueSeries was just perfect for me. It’s really worth the price.

  14. Ashley Sambrano says

    I think PhysiqueSeries should top the list. Anyway, I did not use Instant Knockout while trying to see the best fat burner supplement. I went straight to PhysiqueSeries and I think it should top the list of fat burner supplements following the kind of effectiveness it offers.

  15. Luciana Jack says

    I am 3 months pregnant but I want to shed some of these unpleasant fats before my baby comes. I will like to know if this fat burner will have any side effect on me or my baby. I will appreciate your response to this effect. Many thanks!

  16. Anna says

    Hi guys,

    i have never posted on things like this before but here goes.

    i am currently following a joe wicks lean in 15 fat burning diet and it’s not been too good. i have found your list to be the best and most honest when it comes to fat burners so far and have put an order in for instant knockout.

    (i tried fit affinity, but it was a waste of my time and money)

    my big question is how well do you think this fat burner will work with the joe wicks lean in 15 stuff? i do workouts around 3 times per week at home and then i try go to the gym once too.

    im looking to just burn away fat from around my tummy. i know nutrition is key, but im really hoping instant knockout works with nutrition.

    thanks for this list of top 3 fat burners anyway, its very helpful and your fat burner reviews are easy enough for even me to understand!

    look forward to hear more. heres a good joe wicks workout for doing too if anyone needs one –
