Summary:
HCG that comes from a humans urine has found to have possible trace deseases that go undected through the process and leave a small percent chance that the user could be injecting their body with disease. Doctors have since developed a much better drug to do the same thing CHORIOGONADOTROPIN under the name Ovidrel comes in a 250mcg powder and seperate liquid vial that are disolved the same way as your regualr HCG only the new version doesnt have the"h" in front this is because the took humans out of the equation and made a synthetic version that is far more powerful just 250mcg of the synthetic version is equal to 20,000 iu's of hcg and can be found at half that price and much safer to use.
plenty of articles can be found by typing in "ovidrel 250 mcg" into googles search engine the way i have spelt it including quotes
