The cores from the non-Custom subliminals are all available through the Q store. They 're purchased as modules there, similar to everything else. So, if you look through the modules in the Q Store, you’ll see Emperor Q core module, Stark Q core module, Ecstasy of Gold Q Stage 1 Core module, and so on.
To build a custom with ‘Stark’ and ‘IQ and Cognitive Booster’, you’d have to buy the Stark Q core module in the Q store (yes, even if you already own the standard Stark program). You have to buy the Stark Q core module in the Q store because only the modules from the Q store are configurable and able to be combined with other modules.
An analogy: the modules in the Q Store have ‘USB ports’ and other products can be ‘stuck into’ them to create unique combination products. The programs in the standard store do not have USB ports and are made as stand-alone products.
or another analogy: the products in the standard store are smooth bricks. the modules in the Q store are Lego bricks.
If you want the combined results of two programs in the Standard store, then you buy both of them and then you play them consecutively, one after the other. Now you have a ‘stack’ that is 2 hours long.
In the Q store, you can buy the modules from those same two programs and combine them together into a new, unique subliminal (that is still 60 minutes long).
