The FDA didn't stop the sale of homeopathic drops. My local HFS carries three brands (Anu Med is one of the brands), and I can get the DesBio ha2cg from my doctor.
I haven't mixed my first injections yet, but if I had 5000 iu in one vial, I would need 10 ml of bacteriostat water. My understanding is that I will use a mixing syringe (mine is 10 ml, which is larger than the 1 ml injection syringes), to remove a small amount of water from the bacteriostat water bottle, and inject it into the hcg vial. Then I will roll the hcg vial in my palms to mix (no shaking). Then I will take the same mixing syringe, and use it to extract the mixed hcg from the hcg vial, and inject that into the bacteriostat water bottle (if I don't get it all out the first time, I can go back with the needle to extract the rest). If my bacteriostat bottle is larger than 10 mls, then I would need to use empty, sterile mixing vials, so that you would just end up with 10 ml of water in your solution. If that were the case, I would still put some (1 ml) bacteriostat water into the hcg vial, and take that mixture out and put it into the sterile mixing vial. They I would get the rest of the necessary bacteriostat water (9 ml) and inject that into the mixing vial, so my hcg is mixed with 10 ml of bacteriostat water. HTH
