Can an Alchemist end his mutagen effects early?

[Ajax, The Warrior]

I looked everywhere in the Advanced Class Guide but didn't see anything that said the Alchemist could end a mutagen early... Not sure if it's not in the book or if I'm just missing it.

[Fernn]

"Upon being imbibed, the mutagen causes the alchemist to grow bulkier and more bestial, granting him a +2 natural armor bonus and a +4 alchemical bonus to the selected ability score for 10 minutes per alchemist level."

Nope.

Similar to how some spell have the option of
"dimiss"
or
"stop concentrating"

Other spells like create pit, you just have to wait it out.
