.1 Instant Knockout Fat Burner – Big Dose, Proven Results


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.

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.

  • Stay focused, with more energy and LESS appetite
  • Full body fat burn, 24/7 from high 4 capsule dose

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. We couldn’t find as many testimonials online and when we used it experienced some sides effects.

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

The good:

  • Premium brand
  • Green Tea is a proven fat burner
  • Used by athletes, works well with heavy gym sessions
  • Grenade offer support on MACRO counting
  • Widely available

The bad:

  • Small Daily Dose
  • Citrus aurantium can cause interactions and side effects with caffeine
  • No guarantee
  • Some side effects reported due to ingredients interacting

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.

    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

    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

    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

    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

    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

    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.

  7. Rachael Jens

    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 Post author

      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 🙂

      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

    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!

  9. Perpi

    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

    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

    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.

  12. Gail Val

    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

    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

    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

    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

    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 –


    1. Fat Burner James Post author

      Hi Anna,
      Yeah I’ve seen Joe Wicks. He’s a nice guy and has some really good recipes.

      As long as you are training those 3 times a week and eating clean (as Joe Wicks does) you will get good results from Instant Knockout.

      You could probably burn fat with it, just off a slight diet. However the exercise will help. Try and keep meals spaced and smaller, and ALWAYS try and have a capsule when you feel like snacking.

      Hope this helps! – There’s loads of Information on how to take Instant Knockout on their website http://www.instantknockout.com/how-to-take

    came across this from the fat burner tip on green tea.
    very useful and have just read a bit of the very long instant knockout review hahah

    as far as top 3 fat burners go you have one of the best top 3s as they all look great and have good ingredients.

    I am not convinced yet though as I’m worried the caffeine in instant knockout or grenade will keep me awake too much. I’m 46 and need to lose lots of weight quite fast ideally lol

    1. Fat Burner James Post author

      Hello Alan.

      There is around 75mg of caffeine in Instant Knockout.

      If you ensure you don’t take it too close to bed you’ll be fine.

      Remember drinking green tea has benefits too, if you don’t feel commited to a fat burner just yet.

      You can also check our other fat burner reviews as we have covered some caffeine free supplements.

      Thanks and good luck

    I’ve seen other top supplement lists –


    You are pushing different supplements to them and I am confusing myself as to which supplements and why. Can you please help me choose and supplement and find out which one will work best?

    I’m currently wanting to lose fat around my belly. I do do gym 3 times per week and eat ok too! So think a new fat burner supplement will help me.

    Thank you

    1. Fat Burner James Post author

      Hello Julio,

      Thanks for taking the time to message.

      We firmly believe that Instant Knockout is the best fat burner on the market at the minute. Whilst it may help you lose that belly fat, you need to be sure that you are training enough and eating clean to help make a start on it too.

      Fat burning is a slow process but one that a fat burner like Instant Knockout can speed up, you just need to be sure you need it!
