i think CDL (maybe the same as CDS) is an invention of Andreas Kalcker. i met him in May 2012 in Puerto Vallarta, Mexico where he gave some presentations at the MMS training course i attended. i liked him, and he is very knowledgeable. We were shown how to make CDS ?CDL, and i think it's an easier way to take Chlorine Dioxide as you don't need to mis it every time, and maybe easier on digestive system. But my memory is not too clear on that.
i prefer to stick to the original way as taught by Jim Humble, and i think it's way cheaper too, especially if you make from scratch as i do.
The Health Recovery Protocol in the MMS Health Recovery Guidebook refers only to MMS not CDS/CDL
If you prefer the latter best to read Andreas's stuff: https://search.sapti.me/search?q=CDL+andreas+kalcker
i have pdf of his recently published Forbidden Health book too (in English). He is German though so for sure you can find in German.
There's also video of the same name which i watched about 10 yrs ago (on YouTube i expect), very good, but book will be more up to date.
