When taking DMSO in capsules

Hello everyone.
Please give me some advice.
My brother has anal cancer.
He started taking MMS. He finished start procedure and protocol1000,
1000plus.
He will reach Protocol 2000 tomorrow.
He finished start procedure and protocol1000.
(Now 3 drops / 1 time x 8 times). He plans to increase MMS1 from tomorrow and start taking MMS2 on the 4th day.
He hates the taste and hard to drink. When Protocol 1000 Plus,
He drinks MMS1 and DMSO with apple juice. Can he drink with tomato juice?
From now on, he intends to use capsules as well.
How does he take DMSO when using capsules?
Is it okay to put DMSO in the same capsule with MMS1?
Or is it in another capsule?
Or is DMSO can not use a capsule?

Is there any other effective treatment?
Please tell me. Thank you.
