Well for one thing, both of these are not good instructions. First off, 200 iu is too high of a dose for most people. It used to be good but the hcg got more potent or something about 2 years ago. I would mix a 5000 iu vial with 10 cc (or 20 if you want to mix the way Dr. Simeon did) then start at a dose of 150 iu which would be 30 units (or 60 units if you mix the Simeon way.) Even 150 might be too high and you may need to nudge it down a bit. We see way more hunger on a dose that's too high rather than one that's too low. Both of these mixing instructions provide a mix that's easy to adjust. Good luck!
