SynTech™’s fat burner is one of the most advanced of its kind on the market. Its formula is based on extensive scientific research on fat burning. During the development phase of Synedrine, SynTech™ wanted to meet three requirements:


  1. The product needs to be effective and has to be based on scientific research
  2. It has to meet the strictest health and food security requirements
  3. Synedrine should not make you feel like your heart is racing



Synedrine contains a blend of 7 synergistically interacting ingredients which increase fat burning.



Suited for:


  • Persons that want to reduce their fat percentage
  • Athletes that need to lose weight due to weight categories in their sport
  • Body builders during prep- and depletion phase






Key ingredients per daily serving

  • A stack of 210mg EGCG (extracted from Green Tea) and 317mg of Caffeine (extracted from Guarana). Both the catechin Epigallocatechin Gallate (EGCG)⁽¹⁾⁽²⁾⁽³⁾ and caffeine⁽⁴⁾⁽⁵⁾ have a positive effect on weight loss on their own. Supplementation with either one of them results in decreases in body mass index, waist circumference and total cholesterol.


Several scientific studies⁽⁶⁾⁽⁷⁾ show that the combination of EGCG and caffeine is even more effective. The combination increases fat burning at rest by 180 kcal⁽⁸⁾ and leads to improvements in body composition and reduces abdominal fatness.⁽⁹⁾

During a meta study, scientists of the University of Connecticut put together and analyzed overall data of 15 studies.⁽¹⁰⁾ They concluded that fat burning is stimulated by combining green tea with caffeine:


First of all, phenols in green tea slow down the enzymes that break down adrenaline and noradrenaline. Increased levels of these substances stimulate the transport of fat cells in the blood, making it easier for the muscles and organs to break them down. On a cellular level, phenols produce a similar effect. The phenols found in green tea, e.g. EGCG, stimulate the mitochondria in the cells to burn more fatty acids, and caffeine makes the cells to react better to adrenaline and green tea. A dose of 150mg of caffeine increases fat burning by 33 percent. Adding 210mg of EGCG (the most active polyphenol in green tea) even increases fat burning up to 41 percent! SynTech™ uses a mega dose of 1400mg of green tea (standardized at 15%) in order to reach a daily dose of 210 mg of EGCG.


  • 200mg Capsicum Annuum

Capsicum annuum is an extract of Red Pepper. During a clinical study carried out by the University of Oklahoma, capsicum annuum was administered to a group of people 60 minutes before they were asked to do physical exercises. Compared to another group that got a placebo, the people of the first group turned out to burn 278 calories more before, during and after the physical effort.

This study confirms findings other research: capsicum annuum intake improves thermogenesis⁽¹¹⁾ and enhances the energy expenditure and fat burning and therefore is an important factor leading to weight loss⁽¹²⁾ and abdominal fat decrease.⁽¹³⁾



  • 400mg Svetol®

Svetol® is a extract of decaffeinated green coffee and has a considerable effect on fat burning. It reduces the body mass index (BMI), regulates blood sugar levels and increases lean muscle mass after 60 days. This was one of the conclusions from a clinical study carried out by the manufacturer in cooperation with the INRA, the French National Institute for Agricultural Research.⁽¹⁴⁾

Svetol® consists for about 50% of chlorogenic acid. Chlorogenic acids are polyphenols which have antioxidant effects and have been proven to be very effective for losing weight. According to the study, the recommended daily intake is 400mg, to be taken in one or several doses.

According to another study published in Phytothérapie⁽¹⁵⁾, volunteers with overweight problems who used Svetol®, lost 5kg on average over 60 days.


  • 210mg Taraxacum Officinale

Taraxacum officinale is a plant extract with diuretic properties, as it helps to release excessive water⁽¹⁶⁾  and helps to define and shape your muscles.


  • 250mg Forslean®

Forslean® is the patented extract from the Coleus Forskohlii (standardized at 10% of forskolin). Forslean® stimulates the body to break down existing fat tissue by increasing cAMP levels. cAMP is a molecule which plays an important role in several biological processes, e.g. lipolysis.⁽¹⁷⁾⁽¹⁸⁾


  • 10mg Piper Nigrum

This Black Pepper extract improves the absorption in the blood of the other ingredients. It is standardized at 95% piperine. Recent research also shows that black pepper has appetite-reducing properties.⁽¹⁹⁾
