Hitler's drug consumption evolved significantly from 1941 to 1943, with a marked interest in potent substances and hormone treatments. His personal physician, Morrell, leveraged a monopoly on animal organs from the slaughterhouses in occupied Ukraine to create experimental concoctions. Despite the challenges of wartime economics limiting new medicines, Hitler declared himself a guinea pig for Morrell’s dubious concoctions, bypassing regulations in a bid to enhance the health of the German people. As Hitler consumed increasing amounts of these animal-derived drugs, his health deteriorated noticeably, with marked aging occurring within just a few years. The extensive use of organ extracts, such as those from pig livers, coupled with a lack of medical oversight, contributed to a significant decline in his physical and mental well-being by 1943, showcasing the dangerous consequences of his unregulated experimentation.
