Question about BUD

It’s time for a refill and I am using fifty410 again. I have only ever used BPI w/ b6, but now they only have ProRx pure Tirz. My BUD with BPI was like 1 year (60 mg in 2 vials), has anyone recently received the pure from ProRx and what was the BUD? I asked Fifty410, they said the BUD would be 6/2026, but just wondering if it could be different from the actual pharmacy? (3 month supply 144mg) With current dosing this would last me way past 6/2026
