I am not sure if you can get them anywhere else, but you can definitely get trial sizes above.
Lots of positive reviews about these products around the web,
I am not sure if they are all CG but the Just Gel, the Moisture Gel, and the Shapeshifter I can remember are, and probably some others too.
I got a couple of testers - I emailed them as wasn’t sure what to do with one and got a quick and helpful reply from the Original Moxie owner. So far I’ve tried the Just Gel which is flaxseed based as far as I can see and also it is not crunchy! Seemed like soft hold, maybe could have used more though.
