I got my doctor to prescribe me HCG and when I picked it up the lady told me the I should be getting 8 of them and they only have 1 at the moment and the other 7 will be in this week. From what Im reading is that I can take a 10ml of bac water and remove .5ml of it and add the Ovidrel into the 9.5ml of bac water and will equal to 10,000iu's of HCG. Does anyone have any info on this or takes this brand in the prefilled syringe? And do I really need 8 of them? Seems like it would all go to waste. Please help me out so I know if I should call and ask for another brand.
