Why doesn the HCG come in pre-filled syringes?
The pharmaceutical manufacturer of the HCG you will receive is based here in the United States. The medication contains 2 vials which must be reconstituted (mixed). One vial is the HCG in a powder form and the other is a sterile protein bacteriostatic water which when mixed together has a 100% stable shelf life of 60 days in your refrigerator. It is also important not to leave the HCG vial at room temperature for more than 6 hours, which can decrease the stability.
