Thermo Rip is a fat burner that’s made in the USA by Fitness Labs. The company is based in California and has been trading for more than 18 years.

I’m going to begin this review by pointing out Fitness Labs doesn’t market Thermo Rip as a fat burner for general use. It’s not for the average person who needs help to lose weight. The company developed Thermo Rip especially for people who like to work out and want to get lean and ripped.

As any handyman will tell you, it’s important to choose the right tool for the right job. If you were to use Thermo Rip Fat Burner without a keen focus on training, it would be like trying to use a wrench to hammer in nails. Sure, you might make some progress but the task would be much easier if you selected a hammer instead.

On the face of it, Thermo Rip Fat Burner looks like it may be a pretty good product. However, although it boasts some respected ingredients, in the majority of cases, the inclusion rates are unknown.

That may not be a problem if the product had plenty of customer reviews. Unfortunately, it does not but, if you are strapped for cash, this product does have an attractively low price.

But how good is Thermo Rip Fat Burner and should you buy it? By the time you have finished reading this review, you will have all the tools you need to help you decide.


Thermo Rip Fat Burner: The Promised Benefits

According to Fitness Labs, Thermo Rip Fat Burner can help you to get “lean and ripped” by providing three key benefits:

  • Enhances Metabolism
  • Reduces Body Fat
  • Increases Energy


Things to Bear in Mind

Like other weight management products, Thermo Rip Fat Burner is a supplement. It’s important to understand what a supplement is and never to see any form of supplement as a magic pill.

The word “supplement” refers to something you get or use in addition to something else. For instance, Some people work two jobs to “supplement” their income.

Diet pills and other weight loss supplements, supplement the efforts you are already making by controlling your diet.

In this case, it’s important not to see Thermo Rip Fat Burner as a product that provides an excuse not to try and eat healthy foods. The pills will work best if you use them alongside a healthy diet that contains nutritious foods that are low in fat and sugar.


Thermo Rip Fat Burner: List of Ingredients

Each (2-capsule) dose of Thermo Rip provides 1,075 mg of Thermo Rip Complex. It’s a proprietary blend.

The Thermo Rip proprietary blend is a combination of five ingredients:

      • Sinetrol-Xpur
      • Green Tea Extract
      • Caffeine Anhydrous
      • L-Tyrosine
      • Cayenne Pepper

The ingredients in the list above are correct at the time of this review but the Thermo Rip Complex has been changed at least once in the past. I found an earlier version that did not contain any green tea but had some guarana.

If the formulation has been changed before, it may change again and any change that takes place will alter the blend’s performance.


How Good is Thermo Rip Fat Burner? (A Look at the Formulation)

The problem with proprietary blends is, although you know what the ingredients are, you seldom know the quantities involved.

When you look at this formulation the first thing you notice is a lot of fruit extracts. That can be quite appealing to anyone who prefers products that have natural ingredients instead of chemicals.

However, Thermo Rip Fat Burner contains caffeine and there is no way to know how much of each one is there. Some people have problems tolerating stimulants. Even low doses may make them feel jittery and unwell. Others can handle much higher doses without issues but a minority of people cannot handle stimulants at all.

When you don’t know how much of an ingredient is present, you cannot predict what benefits or side effects it might present.

Nevertheless, let’s take look at the individual ingredients one by one and the theoretical benefits they may provide:



OrangesSinetrol-Xpur is a proprietary blend that provides a combination of three citrus fruit extracts (grapefruit, sweet orange, and blood orange).

Fitness Labs makes a big deal of pointing out a connection between the three fruits and the Mediterranean diet but it’s a pointless comparison. People eat oranges and grapefruit in the Mediterranean–so what! People eat these fruits all over the world.

The Mediterranean diet is based on the foods people eat in the Mediterranean area. It’s the foods people do and do not eat in the Mediterranean area that makes their diet so healthy. To the people who live there, it’s nothing special. All they are doing is eating their normal foods.

Sinetrol-Xpur is manufactured by the French company Fytexia. The three fruit extracts are standardized to provide consistently high levels of polyphenols.

Can a few fruit extracts help you to burn more fat? Several studies suggest that in the case of Sinetrol-Xpur the answer could be yes.

One of the most commonly referenced studies was conducted by researchers in Korea. It ran for 12 weeks and 100 overweight or obese people took part. However, 14 of them dropped out during the trial.

Nevertheless, the data concerning the remaining 86 volunteers suggests Sinetrol-Xpur can help accelerate fat loss.

The participants were given two tablets once per day. Some of them got tablets that contained the fruit extracts, the rest got tablets that provided a placebo.

After 12 weeks, the people who got Sinetrol-Xpur had achieved a reduction in body fat that was significantly greater than that of the placebo group. The same was true for the other two important parameters–body weight and BMI.

The tablets that contained Sinetrol-Xpur provided 450 mg per 2-tablet dose.

Although Fitness Labs, does not reveal any inclusion rates on the label, the Thermo Rip information page on the company website states a 2-capsule dose of Thermo Rip provides 450 mg of Sinetrol-Xpur. This is the same dose as the study participants got but people who use Thermo Rip Fat Burner will be getting that amount twice per day instead of once.

Green Tea Extract

Green tea is one of my favorite diet pill ingredients. Apart from being a proven fat burner, green tea is loaded with antioxidants that can purge toxins from your body and help you to enjoy better health.

The green tea antioxidants that are so beneficial to the health also contribute much to green tea’s abilities as a fat burner. They contribute to the energy shortage your diet provides by increasing metabolism and thermogenesis.

There is a mountain of research that supports using green tea for fat loss. Some of the studies show the value of green tea in additional areas as well.

For instance, the results of a study from Japan illustrate green tea’s ability to burn body fat, lower cholesterol, and help protect against cardiovascular disease.

(The study data is available online:


Caffeine Anhydrous

Caffeine anhydrous is a caffeine concentrate. If you were to look at it, all you would see is a white powder. It’s very potent though. It’s also absorbed quite rapidly into the body.

As you are probably aware, caffeine is a powerful stimulant that’s good for boosting energy levels. It’s equally useful for enhancing mental focus and improving concentration. Millions of sleepy-eyed coffee drinkers can’t be wrong.

Caffeine is also a proven fat burner. A number of studies prove it can increase metabolism and help you to burn extra fat. However, the results of one of these studies indicate caffeine’s effect on body fat be greater for normal-weight people than it is for people who are obese.

(This study is also available online. You can read it here:



L-Tyrosine is an amino acid that’s present in supplement formulations of all different types.

Supplement manufacturers add L-Tyrosine to nootropics because it supports improvements in mental function and is very useful for reducing stress.

Further details here:

L-Tyrosine is often added to sports supplements because it appears to improve athletic performance while also supporting improvements in stamina and strength.


Cayenne Pepper

Cayenne is one of the main fat burning ingredients in Thermo Rip Fat BurnerCayenne is another one of my favorite diet pill ingredients. Like green tea, it’s a safe fat burner that has a mountain of research that supports using it as a weight-loss aid.

When I review products that provide cayenne, I often link to several studies in particular. One of them proves cayenne’s value as an appetite suppressant. You can find it online here:

However, although cayenne has inarguable value as an appetite suppressant, it generally gets more attention for its capabilities as a fat burner.

A lot of studies prove cayenne helps you to burn extra fat. Here’s one that I link to quite a lot of the time:


How to Use Thermo Rip Fat Burner

Bottle of Fitness Labs Thermo Rip Fat BurnerThe dose is two capsules, two times per day, taken with water. The label warns against taking more than the maximum dose of four capsules per day.

You take the first two capsules before eating breakfast. You take the second dose just before your afternoon meal.

Thermo Rip contains caffeine. Taking it too late in the day could lead to problems with insomnia so it’s good to see the final dose is taken in the afternoon rather than the evening.

Fitness Labs advises new users to tread carefully at first and only take one capsule two times per day. They suggest continuing with the half dose for a full week to assess tolerance. This precaution is undoubtedly due to the presence of caffeine in the formulation.

The Thermo Rip usage guidelines also stress the need for using the pills in a cycle of eight weeks on followed by four weeks off.

That means if you still have fat to burn after you’ve been using the pills for a couple of months, you will have to endure a month without supplementary support.

If you need a fat burner that can provide ongoing support, I provide details of a couple of good alternatives to Thermo Rip at the end of this review.

Health Considerations

If you are pregnant or nursing a child, please don’t take any kind of supplement without getting clearance from your doctor first.

If you have an existing medical condition of any kind at all, it would also be unwise to use supplements without checking with your doctor first.

Certain supplement ingredients can present interaction issues when combined with medication. It doesn’t matter if the medication has been prescribed by a doctor, a dentist, or another medical professional. If you are taking medication, don’t use it with supplements without asking a doctor first.

Thermo Rip Fat Burner Customer Reviews

I was unable to find a reliable source of customer reviews so was unable to find out how well the product performs.

Some sites that appear to stock the product have a few reviews that are a mix of good and bad. However, Fitness Labs does not appear to distribute its products via the sites I found so it’s probable the customer feedback has been left by people who unknowingly purchased counterfeit products.

Feedback that has been generated by the sale of fake products will not present a realistic picture of how well the real Thermo Rip Fat Burner works.


Thermo Rip Fat Burner Side Effects

Fitness Labs does not reveal if any side effects have been reported. However, Thermo Rip Fat Burner contains caffeine so side effects cannot be ruled out.

Possible side effects may include nervousness, irritability, and/or rapid heartbeat. The risk of side effects will greatly increase if you use Thermo Rip Fat Burner alongside other stimulants or caffeinated products.


The Best Place to Buy Thermo Rip Fat Burner

The Fitness Labs website makes it very clear, it only distributes its products via Nutrition Express. However, when I was researching for this review, I noticed Thermo Rip Fat Burner appeared to be available via several other online sources including eBay and Amazon. This suggests there may be a problem with counterfeit products. If you decide to buy Thermo Rip, I suggest only dealing with Fitness Labs’ chosen marketing partner–Nutrition Express.

At the time of this review (May 2021), it was possible to pick up a bottle of Thermo Rip Fat Burner for just $19.99. Each bottle provides a 30-day supply of capsules, so the price is very reasonable. Shipping costs are extra but this is still a cheap fat burner to buy.


Customer Support & After-Sales Service

Fitness Labs doesn’t make it easy for customers to get in touch. However, although the company website doesn’t provide a contact page, contact information is available at the bottom of the site’s “About Us” page.

The fact that contact options are so hard to find appears to be more due to a problem with the site design rather than an intention to be elusive. The page provides the number for a 24-hour customer helpline and an email address. It also has the company’s street address in St. Torrance, California.

So if you need to help with a query, before or after the sale, customer support is available. However, if you are unhappy with your purchase, you will probably be out of luck because Fitness Labs doesn’t appear to offer a money-back guarantee.


Thermo Rip Fat Burner Review: Diet Pill Ninja Conclusion

The Diet Pill Ninja: Honorable Diet Pill ReviewsFitness Labs makes three main claims for this product. They say it will (1) enhance metabolism, (2) reduce body fat, and (3) increase energy. It contains ingredients that may help it do these things.

However, we only know one dose for certain. Two capsules provide Sinetrol-Xpur in an amount that’s proven to be effective.

As for the rest of the formulation, it’s got good bragging rights because green tea and cayenne are a powerful combination. At least they can be if they are included in sufficient amounts. In this case, we don’t know if that is so.

Most of the energy boost the formulation provides will probably be due to caffeine. We don’t know what the caffeine inclusion rate is either, but caffeine anhydrous is one of the cheapest ingredients available to supplement manufacturers so they are more likely to be heavy-handed than they are to be stingy.

Here lies the problem though. It’s never good to presume and, if Thermo Rip Fat Burner has too much caffeine, it will increase the chances of side effects.

Customer reviews could provide an indication of the product potency and also reveal any common side effects but there are no customer reviews to read.

Thermo Rip Fat Burner is cheap. There’s no denying it. It’s produced by a reputable company. There’s no denying that either, but it also lacks a money-back guarantee and there is no way to know how this particular formulation of ingredients may affect your body.

The need for cycling is also an issue. Unless you are a bodybuilder who needs help during cutting, Thermo Rip is going to be a poor option. It won’t be able to offer you a consistent level of support. Two months on followed by one month off could easily become a case of two steps forward followed by one step back.

All things considered, I cannot give Fitness Labs Thermo Rip my recommendation but I can recommend a good  alternative.


Phentaslim: A Good Alternative to Thermo Rip Fat Burner

Bottle Vegan-Friendly PhentaslimIf you need a fat burner that can give you more energy and stamina while you train, Phentaslim is probably a better option to choose.

Like Thermo Rip, Phentaslim provides green tea and cayenne. However, the manufacturer provides a complete ingredient profile that shows the tea and cayenne are provided in adequate amounts.

Phentaslim also has caffeine to provide energy. As for the quantity, each dose of Phentaslim is the caffeine equivalent of a cup of coffee. However, Phentaslim also has several B vitamins to further increase energy and there’s some zinc to boost testosterone, along with some ginseng to help improve overall health. Unfortunately, Phentaslim does not have a bargain-basement price. However, it does have a 60-day money-back guarantee.
