Ingredients Label
Active Ingredients
Whey and Casein Protein
Both whey and casein are proteins which are found in cow’s milk.
They have both been shown by research to be very effective for improving muscle development (1, 2).
Although they have similar effects, they are absorbed at very different rates; whey is digested extremely quickly, whereas casein is much more slowly absorbed.
Acetyl L-Carnitine
Carnitine is an amino acid which may improve fat-loss.
It’s been shown to be effective in those who are deficient in it, but not those who consume enough through food.
The acetyl form of carnitine may also improve concentration and insulin sensitivity (3).
The effective dose is about 2g.
Green Tea
Green tea extract contains fat-burning compounds called catechins.
It’s been shown to boost fat-oxidation by significant amounts when combined with exercise (4).
The effective is around 500mg.
Theanine
Theanine is an amino acid which improves relaxation (4).
It can increase concentration when under stress or when taken with stimulants like caffeine.
An effective dose is 100-200mg.
Caffeine
Caffeine is a stimulant which can increase energy levels and metabolic rate.
Supplementing with caffeine can speed up fat-loss, even at rest (5).
The effective dose is about 200mg.

Conclusion
Burn Complex Thermo Protein is an excellent fat-burning protein powder.
Unlike most other products in the same category, it has an open-label formula, and contains much more substantial doses of fat-burning ingredients.
It also contains both whey and casein protein, which supplies a long-lasting stream of amino acids to the body for muscle growth and repair.
The price is reasonable, with a tub costing about the same as plain protein powders which don’t contain any fat-burning extras.
