i just got a box of serostim 6mg it says on the box 6mg(approximately 18 iu) but when i checked the water which is 1ml it only came out to be around 12 iu.
i dont understand there are 7 vials of water(1 ml) and 7 vials of powder and if it 18 iu per vial like it says on the box then why when i mix it it only comes out to be 12 iu?
please some help
