So how long is HCG good for, once reconstituted?
I see some suggest "30 days", but how long is it really?
Well, the answer from Organon Pregnyl, who makes HCG is, "Reconstituted solution is stable for 60 days when refrigerated." As confirmed on the package insert.
After "60 days" it may begin to lose potency, but can still be used IMHO.
