I ordered three 5,000 iu vials of Hucog HCG. It comes premixed in a 1ml solution. If I mix the 1ml of Human Chorionic Gonadotropin (HCG) solution with 4ml of bacteriostatic water, I will produce 5ml of injectable HCG. Injecting 1/4 cc would be equivalent to 250ius and injecting 1/2 cc would be equivalent to 500ius of HCG, right?
The only problem is...if I use 500cc's per week (2x250), it would take ten weeks to use it all, and it goes bad in 30 days after being mixed. If I use 1000ius per week (2x500,) it would go bad in five weeks, which is still exceeding the shelf life.
Here's what I was wondering. If I only extracted half of the 1ml solution from the vial to mix for injection and left the other half in the vial, would the other half go bad. It's supposed to last up to two years in the premixed solution. I wonder how much it would reduce the shelf life if you withdrew exactly half of it and left the other half in the vial.
