Dr.Pepper has 23 flavors, I wouldn't be surprised if one of those was testosterone so it would make sense your balls would shrink.
I'm fairly certain they don't put male hormones in Dr. Pepper for flavor.
I've been drinking Dr. Pepper for years and neither my balls nor my tackle have stopped growing at a normal rate, how stupid would you have to be to even consider a ridiculous thing like that being true?
