Yes, you can. In fact, all our subliminals are designed to be stacked with each other, like a grand mosaic piece. Keep in mind that, with each title there is a greater load on your subconscious, and hence the timeframe you are dealing with can be extended.. all depending on the customer, of course. Furthermore, there is a module in the Q store specifically to take stacking further, that will allow you to stack your custom subliminal even more effectively with other titles.
