Is there caffeine in PB2?

I'm curious about the ingredients in PB2 and was wondering if it contains caffeine. Could you please clarify if PB2 has any caffeine in it? I'm interested in consuming PB2 but want to make sure it doesn't have any stimulants that could potentially affect my sleep or energy levels. If you could provide some insight into the ingredients and whether or not caffeine is present, that would be greatly appreciated.
