I would like to know the answer to popeye1's question too.
My friend has 10,000 IU's of Loeffer HCG from mexico. It has a vial with the powder and a vial with the solvent. I believe it is 10ml of the solvent. If he intends to inject 500 IU's M/W/F for 3 weeks should be mix it with Bac Water instead of the solvent that came with it? Where can you get bac water?
Thanks!
