Advertising is a brand, and fitness is a category. You usually drink black coffee, especially those with the task of reducing fat. If you don't like it, add skim milk at most, and the so-called latte will do. If you just gain muscle and don't lose fat, it's not a big problem to add sugar and milk. Of course, it's most convenient to soak in a bag. L-carnitine is popular now, so general fitness is unnecessary. To say the taste, you have to grind the peas yourself. What you drink at this level depends on your hobby. Try it first. Because there is not much difference in caffeine content of coffee beans, there is not much difference in the degree of excitement. Personally recommend Yunnan coffee, which is cost-effective and tastes good. However, the average person's daily intake of caffeine is a reference value-200 mg. It is best to ask the rules before drinking before the game or before the game.
