Instant Knockout Review: A Strong Testosterone booster

The History of Instant Knockout

Instant Knockout is manufactured by Roar Ambitions, a London based company that specializes in the manufacturing of dietary supplements and energy boosters. The company claims that their main clientele is composed of educated men aged between 21 to 30 years seeking the latest ingredients and best formula. The company specialized in producing fat burning supplements and testosterone boosters, which are the two key areas that most men seem to be concerned about, for easy and quick muscle building. The company has a very good chance to expand their range, but given that they are playing within their strengths by the production of these supplements, they have come up with platforms that allow them to develop some of the most effective supplements available in the market today. They are always in consultation with athletes and nutritionists in an effort to get the latter’s insights so that they use the best available ingredients for their products. Their products are updated every 6-12 months.

What is Instant Knockout

This is a fat burning supplement containing 10 natural fat burning ingredients that help your body to burn fat gradually, with little or no side effects. Not all the ingredients contained in this product work for the purpose of fat burning. The product was initially intended to help athletes, especially mixed martial arts fighters and boxers to shed excess body fat faster. It is a formula that helps them shed the extra weight and get ripped without having to worry about portioned eating or losing energy or stamina. The product’s benefits to the athletes include:

  • Synergistic look: just looking at the results of the product will make you realize that the product was well thought out
  • Appetite suppression; Most fat burning products bank on fiber intake. Instant Knockout does not.
  • More than just a fat-burning supplement: it is an added performance booster with lots of caffeine.  

Instant Knockout ingredients

There are three main ingredients making up instant Knockout, but the total composition of the capsules is made up of more than ten ingredients. In this post, we are going to look at the three main ingredients specified by the manufacturer.

  1. Green tea extract: there is a lot of positive documentation about the benefits of green tea extracts. According to a recent study conducted by the University of Pennsylvania where they were gauging the effect of green tea on lab mice with high-fat diets, the conclusion was that the mice exhibited up to 27.1% body mass reduction and 36% abdominal fat reduction after a short while. The mice that did not take green tea extracts showed no changes.
  2. Cayenne Pepper: this is yet another product that is becoming trendy in the market, especially for weight loss purposes. Cayenne pepper contains capsaicin which is the most active compound in chili peppers. According to some research, capsaicin may even have potential effects that work to improve vascular and metabolic health.
  3. Glucomannan: A dietary fiber that absorbs water when ingested to make the user feel fuller for longer. It is claimed to curb hunger and promote satiety.

The other additional ingredients contained in Instant Knockout include caffeine, chromium, piperine, zinc, green coffee beans, vitamins B6 and B12.

Suggested dosage

For maximum performance, the manufacturer recommends that one capsule should be taken four times a day, right before meals. They should be taken with plenty of water. Users should be careful not to exceed four capsules in a day.

How does the product work?

Instant Knockout, just like the name suggests, instantly knocks out the competition with its fat burning strategy and composition formula. The most amazing feature about this product is how it manages to keep things short, yet explosive. All the ingredients contained in the supplement are either backed by science and researches or have previously been used in successful workout products before, this means that instant Knockout is among the best supplements there are.  The only downside about this product is how the manufacturer omitted the use of standardized or premium ingredients. However, the performance of each ingredient in the product has such a big impact on the overall performance of the supplement, making it hard to just ignore any of them.

  • Green tea + Caffeine = increased fat oxidation, metabolic boost, and performance
  • Cayenne + glucomannan = appetite suppression and the ignition to the fat-burning processes
  • Green coffee beans + glucomannan = blockage of the absorption of the carbs and balanced blood sugar which results to even more appetite suppression
  • Black Pepper and everything else included = making every other ingredient more potent.

Benefits of instant Knockout

  •  Fat burning
  • Appetite suppression
  • Spiking up energy levels and alertness
  • Improved physical performance.

Side effects

In most users, Instant Knockout is very well tolerated by their body systems. However, not everybody is built strongly enough for such high-performance ingredients. Cayenne powder, when in raw form, is associated with a burning or hot sensation in the stomach. The 300mg caffeine dosage, on the other hand, may carry some typical stimulant side effects such as irritability, aggression, and jitters. Below are some of the recorded side effects from regular users:

  • Insomnia
  • Irritability
  • Headaches
  • Drowsiness


Just like any other dietary supplement, Instant Knockout should be used responsibly. Only four capsules should be ingested per day, just like it is indicated in the manufacturer’s prescription. A physician should be consulted before combining the supplement with any other medication or before beginning any training or supplement regimen. The company also states that the product is not meant for men exclusively, despite the masculine marketing strategy.

It is a very powerful fat burner, and it does not matter whether the user is male or female, the results are just the same in either. Human bodies tend to burn fat throughout the day, and this supplement allegedly can enhance this process further so that the fat burning process takes place both when you are active and when you are sleeping or resting.

How much does the supplement cost?

The published prices of Instant Knockout are as follows:

  • One month supply (one bottle); $59
  • Two months supply (two bottles): $118
  • Four months Supply (four bottles): $185

You should also note that Instant Knockout comes with a 90 days money-back guarantee. The manufacturer gives you a chance for a test run so that if you are unhappy with the results, you can always ship back the product. This goes to show you how much faith the manufacturer has in this product. That right, there is a mark of quality in itself.

Although many drug stores and supplement retailers do not store Instant Knockout, the manufacturer’s official website offers free delivery when you order more than three bottles, which will come with an added a discount of one free bottle. The manufacturer also offers free deliveries for two bottles ordered from either the US or the UK.

Using other supplements alongside instant Knockout

According to the official website of this product, it is okay to combine the ingestion of this supplement with other supplements, as long as you do not exhibit any adverse reactions after use. However, it would be advisable to seek the attention of a professional before combining this product with prescription medication, especially if you are diabetic.

Instant Knockout already contains 300mg of caffeine for each day consumption. The company, therefore, discourages users from consuming any other form of stimulant or products containing any amount of stimulants. Too much caffeine can cause severe side effects such as nausea, headaches, insomnia, and jitters. The product is also not to be taken late at night because one of the most reported side effects is insomnia.


Although there are a number of comments from customers praising Instant Knockout, there is no recorded evidence that the product has been clinically tested and proven to be containing 100% natural products. There are also other customer reviews that indicate the side effects of the product, which raises even more concerns, especially due to the manufacturer’s safety guarantee claims. One goes to wonder, is everything else true?

If you really want to purchase reliable dietary supplements, it would be advisable to go for products that have been clinically tested and the results published in all marketing channels. You should also consider reviews from real customers to look at the side effects of the product and the most common adverse effect.

Here is the thing about fat burners; none should have a too complicated serving or dosage guide. For everyone interested in weight loss, the more the time spent in the gym working out, the more they miss out on life. Instant Knockout offers them a chance to forget about most of the time spent trying to get ripped and toned so that they can focus on other things. But in the end, you will need to support the supplement with some workouts to get the best results.

The product has exceedingly outdone itself in a number of ways. It attacks fat from different fronts while at the same time preventing the sensation of hunger or cravings, all this while keeping everything simple and short for the athletes. What more could you need?
