There are many types of hCG you can buy - injections, real hormone drops, homeopathic drops, and hormone free drops. Which should you choose? Should you just choose what sounds easiest? Here's some info to help you decide what's best for you. My quick hint= I truly believe in using real hCG hormone first and foremost, and if you end up agreeing, I highly recommend injections. But most important is just using real hCG.
