best way to add candi syrup to fermenting beer?

i have a huge beer that i am looking to add up to 4lbs of candi syrup while it is in primary. i will probably do this in 2-4 stages with 1st addition coming after the 72 hr mark.  i have oxygen to add as well.

main question is- what is the best way to add it?  is there a need to sterilize it somehow?  how?

thanks-

No need to sanitize.  I’d just boil a little water to add to thin it down and make it easier to pour.  Maybe pour as much as will come out easily, add water and swish it around before pouring the rest.

thanks!
