I had bought tetley green tea 3 months ago as per the advertisement they said that by doing regularly exercise & drinking two cups of Tetley Green Tea will helps you in weight loss but it is not at all true as Tetley Green Tea does not have pure contents of Green Tea. Its not at all effective as I am using this from Last 3 months and also continuing exercise. Its taste is also very bad. It has some mixed flavors also the quantity in each tea bag is very less. Its better to go for Lipton Green Tea as it taste much more better than Tetley.
