granto- if you're not hungry and not weak, you're probably ok, and probably able to produce what you need from those Drops. but many people have trouble with them. i really don't recommend any hhcg at this point because so many are taking the hcg out of it- and you don't know how it's made.
sr- you buy the same Rx hcg and mix it for drops. one vial of 5000 iu's will be enough for 15 days. so buy 2 for a 23-30 day round, 3 for a 40-day round.
mixed- just drink a lot of water.
sweet- not familiar with that brand. the Corion is a bit stronger than Ovidac, so i'd go down a touch.
