Did goku use kaioken x100 against slug?

[KyuubiAhri]

where was it stated. I heard i multiple times

 

[Captain Cadaver]

It was stated in a guidebook/pamphlet. Unfortunately, I don't know the source, but I'm pretty sure Kenshi should.

It's also the logical conclusion since Kaioken x100 Goku > Giant Slug > SSJ Goku in this film.
