Karadžić gave lectures in front of hundreds of people on alternative medicine. He even had his own website, where he offered his assistance in the treatment of sexual problems and disorders by using what he called Human Quantum Energy. He also used the site for the sale of metallic bullet-shaped amulets. He advertised himself as one of the most prominent experts in the field of alternative medicine, bioenergy, and macrobiotic diet. Karadžić had been masquerading as an expert in “human quantum energy” using the fake name “D.D. David” printed on his business card. The initials apparently stood for Dragan David Dabić, the name officials said he went by.
