HCG Storage After Reconstitution — Expiry Calculator
Worked example
Counting 60 days from a reconstitution date of 2026-01-01 gives an expiry date of 2026-03-02 for HCG, leaving 60 days in the storage window on day zero.
How it works
Expiry date = reconstitution date + the listed storage window (60 days on the compound record), counted in calendar days. Days remaining = expiry date - the date entered. A freezer window applies only when the record carries a cited multiplier (currently 1).
Frequently asked questions
How long does reconstituted HCG last in the fridge?
The storage window stored on the HCG record is 60 days after reconstitution. The calculator counts calendar days from the date you enter.
How is the expiry date calculated?
Calendar-day arithmetic: 2026-01-01 plus 60 days is 2026-03-02. No clock is read, so the same inputs always give the same expiry.
Does freezing change the storage window for HCG?
Only when a cited multiplier exists on the compound record. The current multiplier is 1, so the freezer window is the same 60 days unless a source says otherwise.
