Typical flavour systems like that BSL produces and a few others are normally only good for bland tasting raws like that of protein powder.
To develop flavour systems for things like CEE, ALCAR, CM, and then any combination thereof would take a lot of work. Why? Because the taste of each of these compunds can affect the taste of the flavour being used.
In other words, most of these compounds need to be masked because they are harsh and "just any old flavouring system" won't always do the trick.
Now, I find Crystal Lite maskes the taste of a lot of compounds quite nicely
