Question right storage since burning feeling

 I have a question about the storage of CDS Plus and DMSO (brand Nature's Gift). I was wondering when the CDS Plus is activated and DMSO is openend, what is the best way to store it? I understood that the CDS plus need to be in the fridge, and DMSO at room temperature, but is keeping it in the original packaging (plastic bottle) possible for storage when using?
I am curious if its stored the right way since I feel a little burning in my belly when using CDS.

What is your hourly CDS dosage? 

How are you storing CDS? 

Thank you for your reaction.
I tried 1 drop of CDS Plus with a glass of water and I stored it in the original plastic packaging bottle (see picture below) in the fridge. I already opened it a couple of times and noticed that the smell got stronger overtime.
I also read in the protocols that if you feel a burning in belly, that it can be mold that needs to get removed first. Maybe you know also more of that?
