To much sugar
To much caffine
They hate you
Your body is growing when you are older you will get a energy boost
They cant test it on animals so we are the beta test
Something that costs $2-$3 will get you the same amount energy it will get you if it was a whore.
People want you to drink it thinking your getting something that makes you a super hero but then you fall asleep on the side walk when walking home and they can pick you up in their mini van and rape you.
Thats really why they dont work.
