BL2 PS Vita Cartridge DLC Question

So I was going to go buy BL2 for PS Vita tomorrow and I can’t seem to find any solids answers to if the DLC is on the cartridge or if it’s download only. So if anybody could help me out and let me know, that would be awesome.

Thank you!

You have to download it

So it’s not like the game of the year editions for the consoles where it’s packaged on disc? Only reason this concerns me is I’m buying it used and not from a store.
