For hCG & the listed 60 days (or 30 days depending on the state that you are in); The discard date (sometimes labeled as expiration date) is not the same thing as a expiration date, and all companies place that on their medications for multi-dose vials because it is the FDA requirement that for 28 days it must remain in the same state & efficiency. However most studies show that it generally takes ~6 months or so for a multi-dose vial to lose even ~6% efficiency in the least ideal conditions (as long as refrigerated). You are fine to hold onto your vial for its full use duration without concern, this is more of a legal protection statement for the pharmacy than anything about medication efficiency.

You can always confirm with the pharmacy, but usually that statement is on every bottle that goes out of any pharmacy because it is considered a multi-use vial. Multi-use vials have to have an expiration date of one month because they're usually used in the clinical setting and that is a requirement. Outside of a clinical environment the vial is still good till the expiration date that a stamp on the bottle.
