Calcium Hypochlorite 65% Granular

I have just bought Jim's book and he advocates taking MMS2 as part of the protocol for breast cancer.  I was just about to buy it from a UK supplier apcpure.com/product/calcium-hypochlorite-65-granular/ but I just wanted to check that I am getting the right thing as it says specifically on the tub "harmful if swallowed"

Any help would be appreciated.

Many thanks.

I have also bookmarked the website as there seems to be a wealth of information on there.  I have been vegan for 5 1/2 years and have been eating McVegan (love that word) for a couple of months, though not as strictly as I should.

 

I looked on your website but couldn't find a link where to purchase or a specific brand for  78%Calcium Hypochlorite 
. could you put the link or for the brand you recommend? thanks
