Q: Do I need to take Pump on non-training days?
A: You should, yes. Animal Pump is a core, foundational supplement (like Animal Pak and Animal Flex)--one that we believe should be taken on a daily basis. If you are looking to stretch out your can of Pump for budget reasons, you can use bulk creatine or Storm for off days, saving Pump specifically preworkout. Having said that, your results may not be optimal.
