No. You cannot stop Alpha Male 5.0 once you start, as the program is specifically designed to shift your focus in specific ways that must be balanced out later, and each stage balances the one before it. Furthermore, AM 6 will have a different script, and will not balance AM 5.0 properly. And last but not least, you will need to have run through AM 5.0 fully before you run AM 6.0.
DO NOT stop using AM 5.0 to use AM 6.0 before you have finished all six stages of 5.0 according to the instructions. DO NOT attempt to just switch from whatever stage you are using in Version 5 to that stage or the next stage in Version 6.http://www.subliminal-shop.com/product/alpha-male-subliminal-training-6/
