Question: How long does it take to grow a moustache? And when does it stop growing?

well in my case 3 seconds to remove the backing and stick it on!

In real life hair never stops growing so if you grew a mustache it would continue to grow until you die. this is why men have to shave their whole lives. How long it takes depends on how quick the hair grows and how many hair follicles you have on your upper lip – its different in everyone!
