Im looking into buying a 6 month supply of 4iu/day after my upcoming cycle.

Im wondering how I would work this since the HGH comes in an 8iu vial and how I could manage to save on needles??

Would I mix the 1mL bac water into the vial and extract once then, another the next day and repeat this process for 6 months??

Can someone walk me through a more convenient way of doing this
