Thermo speed, an explosive combination of ingredients


Today we present THERMO SPEED, a powerful fat burner specially designed for active people wishing to eliminate body fat.

Introducing Thermo Speed

When it first appeared, Thermo Speed was a fat burner specially designed for sportsmen and sportswomen who were on a dry period.
During a dry period, the aim is to lose as much body fat as possible, while preserving muscle mass. The result is a sculpted, well-defined body – the famous dream or beach body.

According to the manufacturer, the benefits of Thermo Speed are as follows:

  • Eliminates fat reserves;
  • Helps maintain muscle mass;
  • Keeps the body’s energy transformation processes running smoothly;
  • Facilitates weight control

The manufacturer recommends taking 2 Thermo Speed capsules a day, before breakfast, before another meal, or before training, with a large glass of water.

The manufacturer of Thermo Speed

Olimp Nutrition is a Polish company with a solid reputation, particularly in the bodybuilding world.
Olimp Nutrition’s products are well known among fitness enthusiasts, who make no secret of their satisfaction with the quality of these products.

Even though the company is located in an Eastern European country, which suggests a lack of transparency, Olimp Nutrition stands out in this respect.
All you need to know is that this manufacturer has its own production units, and a large number of certifications (including GMP, or Good Manufacturing Practice) guaranteeing the quality and safety of its supplements.

Thermo Speed ingredients

1. Caffeine:

Caffeine is recognized by official health organizations as a substance that reinforces and supports weight-loss diets.
Caffeine stimulates lipolysis, i.e. the breakdown and combustion of fats.
It also inhibits the formation of new fatty deposits.
By increasing thermogenesis, it also stimulates metabolism and calorie expenditure.
Finally, as many people already know, caffeine provides an energy boost and stimulates the nervous system, improving concentration and attention, among other things.

2. Guarana:

Guarana is a fruit with multiple virtues.
It acts as an appetite suppressant and natural fat burner.
But that’s not all: guarana is an energetic tonic that gives strength and stamina, and effectively combats fatigue. It also strengthens the immune system and boosts libido.

3. Citrus Aurauntium:

It’s the active ingredient in citrus aurantium, synephrine, that gives it its powerful fat-burning and metabolism-boosting properties.
When combined with caffeine, citrus aurantium’s fat-burning effects are multiplied.
And yet, this ingredient is not without risk!
Synephrine has similar effects to ephedrine in terms of fat burning, but also, unfortunately, in terms of side effects (heart palpitations, anxiety, headaches, sleep disorders…). This is why ephedrine has been banned in France.
The same applies to citrus aurantium, which can only be used in food supplements under certain conditions:

  • Synephrine content must be less than 20mg per recommended daily dose;
  • The label must carry a warning that the product is not suitable for children, pregnant or breast-feeding women, or people suffering from high blood pressure;
  • It is forbidden to add caffeine or caffeine-source ingredients to the composition of the product.

4. Green Tea:

Green tea, rich in catechins in particular, is a well-known ingredient in fat-burning pills today.
Science has demonstrated its fat-burning, anti-oxidant and metabolism-activating properties.

5. Black pepper:

In addition to its ability to stimulate thermogenesis, which increases fat burning, black pepper acts as an ingredient enhancer.
Its presence therefore multiplies the effects of the synergy of ingredients present in Thermospeed.

Scientific studies on Thermo Speed

The manufacturer makes no mention of any scientific studies proving the efficacy of Thermo Speed.

We can, however, mention what science has to say about the various ingredients in its formula.

Caffeine, as we have said, is an ingredient recognized for its ability to activate fat oxidation and thermogenesis.
A case in point is this study to determine the effect of a green tea-caffeine blend on weight maintenance after body weight loss in moderately obese subjects, compared with habitual caffeine consumption.
Study subjects lost an average of 5.9 kg during a protocol that included a 4-week hypocaloric diet, followed by a 4-month stabilization program, supplemented by daily caffeine intake.
Researchers in this study concluded that high caffeine intake is associated with weight loss through thermogenesis, fat oxidation and leptin suppression in women.
The green tea-caffeine blend improves weight maintenance in low habitual caffeine consumers.

Green tea has also been the subject of several clinical studies, demonstrating its efficacy in weight loss and control.
Here’s an article from the University of Maryland Medical Center portal on the benefits of this plant for human health in general.

Side effects and contraindications of Thermo Speed

First of all, we would like to draw our readers’ attention to the presence of caffeine AND citrus aurantium in the Thermo Speed formulation.
The combination of these two ingredients is not recommended by the relevant health authorities, given the risk of side effects it may cause.

In high doses, guarana can have serious side effects, such as palpitations, increased blood pressure, insomnia, nervousness and irritability, heartburn and stomach irritation, nausea and vomiting, and serious dependency.

Naturally, Thermo Speed is not recommended for pregnant or breast-feeding women, or for anyone under 18.

User testimonials on Thermo Speed

A large number of people who have tried Thermo Speed are very satisfied with this supplement.
These users report a significant increase in the sensation of heat and perspiration, a noticeable draining action, improved energy and, last but not least, fat loss, particularly in the abdominal area.

Others, albeit fewer in number, have not observed any conclusive results from using Thermo Speed.

Price and guarantee

A bottle of 120 Thermo Speed capsules, equivalent to 2 months’ treatment, will cost you around 25€.
You can buy this supplement in most sports nutrition and fitness stores.

There is no money-back guarantee on this supplement.

    Hello, I am going to start thermo speed extrême 2.0.

    Knowing that I have a blood pressure treatment I plan to take only one capsule in the morning? Es ce bien?


    • Corinne Kepler

      Hello Dage,
      Have you read our Thermo Speed 2.0 test? You should be very careful with the combination of caffeine and citrus aurantium, especially as you have a blood pressure treatment in progress. Frankly, I wouldn’t risk it if I were you.


    Hello. I don’t know if there’s a connection, but since I started taking this medication I’ve woken up several times with burst blood vessels in my left eye. What’s more, it made me feel shaky. So I reduced the dose to just one capsule after breakfast and the eye finally calmed down.

    So I took two more capsules yesterday (one after breakfast and one after lunch…. and this morning my left eye is worse than ever!

    So today I won’t take anything at all and we’ll see. Now I’m going to the eye emergency room and we’ll see what they tell me.

    • Arnaud Dubos

      You should have stopped using this product completely, since you had eye problems, you shouldn’t have used it again.

      I wish you a good recovery.
