Hi All
My HCG came with 1 vial of 1ml of bacteriostatic water - do I have to use this or can I use 'water for injection'? The reason I ask is I want to mix with more than 1ml to make it easier to use. Will this shorten its shelf life as I'm only using 500 IU weekly and I have a 5000 IU vial.
Cheers
