Have you asked your parents/ guardian? in some countries, you can get pierced younger than stated with your parents/ guardians consent
Are you planning any holidays to any country soon where their minimum piercing age is 16?
I have a few extra questions for you:-
How old do you have to be to vote?
How old do you have to be to drive?
How old do you have to be to be legally charged as an adult?
How old do you have to be to have sex?
How old do you have to be to drink alcohol?
How old do you have to be to join the military?
How old do you have to be to get you ears pierced?
How old do you have to be to read https://dangerousthings.com/wp-content/uploads/Introduction-to-Implantable-Transponders-for-Professionals.pdf ?
How old do you have to be to read https://dangerousthings.com/wp-content/uploads/Professional-Guide-to-2x12mm-transponder-installation.pdf ? 
How old do you have to be to watch https://www.youtube.com/watch?v=Gj5g454AD4E
( I wish there was a Dangerous Things video like this, but I couldn’t find one…)
I know what I would do in your situation, YOU need to decide what YOU will do.
Good Luck
