How many ounces of drops do I need for a round of HCG?

Phase 2 of the HCG Diet (the phase where you take the drops) has a minimum recommended number of 23 days and a maximum of 40 days. Therefore, you need at least a 2-ounce bottle to complete a round. If you want/need to increase your dosage slightly (as some people do), you'll need an additional ounce of the HCG.
