How long can I keep this Halo Halo mix after I open it?

A friend of mine brought me this bottle and I’m wondering how long I can keep it in the refrigerator after opening. It’s a huge bottle and could potentially last me a while, provided it keeps. So…how long? Anyone know? I’m thinking it’s so sugary it should keep for awhile but would like an answer from someone in the know.

The exact bottle I’m looking at is here:

Thanks in advance,

To be on the safe side, I would call the 800 number which is usually listed on the bottle in tiny print.
