An Associated Press investigation this past December found another reason why there hasn't been much federal action to crack down on clinics such as Biogenesis. Big Pharma has been reaping a bonanza off HGH as civilian sales have skyrocketed. Last year, . sales of HGH topped $ billion, the AP found — more than drug companies made off penicillin or prescription allergy meds. This despite the fact that endocrinologists estimate fewer than 45,000 people in the nation actually suffer from FDA-approved maladies for the drug. The reason is simple: The feds have stopped prosecuting anti-aging clinics, and many people believe the drug is a fountain of youth despite a lack of medical evidence and warnings it might lead to cancerous growths and diabetes.
