Also, "oral" drops make no sense (if you ingest the liquid it gets destroyed in your stomach). The only two ways you can administer hCG is by injection (s.c. or i.m.) or sublingual (goes directly into the bloodstream skipping the GI tract). Also the "homeopatic" drops have no hCG in them.
[I'm still doing research on this, will start in a week or so, so please feel free to correct me]
