Homebrew help please?

im looking for those that r experienced at least a little bit in the homebrew hobby even more so those that are into fruity flavors maybe even someone who has tried the oregan fruit in light syrup or heavy syrup style who has used this and how do they use it its basically real canned fruit nothin special about it but my main question is about some smuckers boysenberry syrup almost like the kind you get at ihop but i got it at the grocery store i was wondering if i could or better yet should use this just before the bottling process just add a bit to each bottle maybe? ill provide the ingredients so the seasoned brewers can assist: high frctose corn syrup, corn syrup, water boysenberry juice concentrate, natural flavor , citric acid, pectin, xanthan gum! the real canned fruit doesnt seem it can give the flavor i would expect any tips or suggestions appreciated!
