Drops? Most drops you'll find these days don't actually contain HCG in them, they're just amino acid blends. There was a crackdown on Homeopathic HCG that banned the sale of it. There are some websites that still sell real Homeopathic HCG, I don't know which ones because I'm not using Homeopathic, but someone else might be able to help you or you can search the forum and see if you find anything.
You also have the option of making your own sublingual drops from real Rx grade HCG. Here's a thread on that http://hcgdietinfo.com/hcgdietforums...g-drops-50656/ the disadvantage is that you need to hold the liquid under your tongue for 5 minutes, and you need to buy more HCG, but remember, you're getting more HCG into your system than any homeopathic HCG you'll buy, and you don't need to worry about taking tons of drops 3 times a day. With sublingual drops, you only do it twice a day. I've also found that some of the real homeopathic HCG is pretty expensive, so you could end up spending the same or less by going the sublingual route.
But then there's always the route of just giving yourself injections. I haven't started my HCG diet yet (waiting to receive my HCG), but apparently the needles are so thin that you barely feel anything (they're insulin needles). You inject them in the area around your stomach. I don't know if you gave them to yourself when you did it 2 years ago or if your doctor did, so just throwing this part in anyway.
