Save Lower Doses?

Not in maintenance yet myself, but would like feedback from the experts here.

I'm due to move up a dose as I've stalled for four months on 5. Due to shortages making me want to fill early, I still have 2 2.5 mgs and a full box of 5 mgs.

Will I want these lower dosages as I experiment in maintenance? Should I keep them around? Or should I use them now, while my hunger levels are lower because my weight is still higher?

Thanks for your help!
