Ingredients can make or break the drink(DUH) Poor raw materials can have some major taste issues as well as quality issues. Research sources tirelessly to get the best raws at the best price. Cheap aint good and good aint cheap!
Believe it or not not all 250mgs of caffeine are equal.Same goes for Yohimbe, notice some drinks with Yohimbe have small twig like particles floating in the bottom while others don't. This is due to cheap raws being used to cut cost.
If you have to charge a little bit more for your drink due to higher quality materials I wouldn't sweat it to much. The consumer knows when they are getting what they are paying for and vice versa.
Whether you think can or think you can\'t, you\'re probably right!
