I have 4 ampules of HCG @ 5,000iu each and they come with 4 companion ampules of solvent @ 1mL each. That suggests that I would mix 5,000iu HCG with 1mL solvent and that would mean that every 1mL = 5,000iu. This seems a little strong, especially if I want to do 500iu a week- I would have to inject .1mL at a time?!?! Does this sound right?
