You can put it without loctite if you don't have it.
Order some, and if it squeak one day( which most of the time is not the BB ) you can add it at that time, as it probably don't hurt.
I tried both options on my bikes, and no squeak so far from there.
I had squeaks, once it was the headset, and another time it was a pedal.
Both times I would have sworn it was coming from the BB.
Twice unmounted, checked, replaced the bearings, +loctite for nothing
