Arnold Schwarzenegger admits past steroid use
Saturday, February 26, 2005
AS a young body builder Arnold Schwarzenegger used experimental steroids on doctors' recommendations, the movie-star-turned California governor admitted in a television interview today, calling for a youth ban on steroids.
"That's what we did in those days," the star of Terminator said, quizzed on the American ABC network's News This Week with George Stephanopoulos. "But I would strongly recommend that people do not take drugs."
Asked on the ABC News program, due to air fully on Sunday, if he had regrets about using steroids, he replied: "No, I have no regrets about it, because at that time, it was something new that came on the market, and we went to the doctor and did it under doctor's supervision.
"We were experimenting with it, it was a new thing."
The California governor said that, "absolutely" he planned to advance his own steroid legislation, after his veto of a bill that required high school coaches to teach student athletes the dangers of steroids.
Schwarzenegger said he vetoed the bill because performance enhancing food supplements had been included alongside steroids. "It's ludicrous to forbid this for a student to take. Because if you take a protein food supplement that is made out of milk protein, out of milk, or out of soybean, or out of liver or fish that has maybe 90 percent protein, they will enhance your performance. "That's what you need in order to get strong, is protein."
The California governor said he would seek a ban on steroids, but without food supplement restrictions. "Of course, we want to keep the sport clean. It says, 'body-building', not 'body-destroying'. "But people should take food supplements, people should be able to take the vitamins and all of the nutritious stuff that is available, but stay away from drugs."

Dianabol Godfather

The Man Behind the Juice
Fifty years ago, a doctor brought steroids to America.
The BALCO scandal and Jose Cansecos best-selling book Juiced have kept steroids on the front page of the sports section for months. Yet athletes have been pumping themselves up with anabolic steroids for nearly 50 years, long before the days of the cream and the clear. So, who is responsible for bringing steroids into the sports world?
The godfather of steroids was a rough-and-tumble Maryland physician named John Bosley Ziegler. Ziegler practiced medicine in Olney, Md. and conducted chemistry research at a company called Ciba Pharmaceuticals. A big, fleshy former Marine who answered to the nickname Montana Jack, Ziegler loved to pump iron. During his long sessions at the gym, he befriended several bodybuilders associated with the York (Pa.) Barbell Club. In the 1950s, York was at the center of American fitness training, and Bob Hoffman was the movement's spiritual leader. Hoffman, who competed with Joe Weider and Charles Atlas for the title of Americas main muscleman, also ran the York Barbell Co. I am proud that I am a builder of men, he wrote in the 1939 book Weight Lifting. The men he built included such famed old-time strongmen as John Grimek, John Davis, and Paul Anderson.

Advances in Recombinant Human Growth Hormone Replacement Therapy in Adults
by Steven Grinspoon, M.D. , Harvard University
Acquired growth hormone (GH) deficiency results from the destruction of normal pituitary and/or hypothalamic tissue, usually from a tumor or secondary to surgical and/or radiation therapy. Diagnostic criteria and clinical sequelae of GH deficiency, although well established in children, are currently areas of active investigation in the adult. It is now apparent that acquired GH deficiency is associated with significant changes in body composition, bone density, lipid metabolism, cardiovascular function and physical performance. In addition, new information is now available on the use of low doses of recombinant human growth hormone (rhGH) to reverse the sequelae of GH deficiency in adults.
The Growth Hormone Deficiency Syndrome
Acquired GH deficiency is characterized by weight gain, increased fat mass and decreased lean body mass. In one recent study, total body fat was shown to be increased by 7% in this population while lean body mass was decreased to a similar degree (1). The increased fat mass is found in a truncal distribution, thereby increasing the waist:hip ratio. In addition, triglyceride levels are increased and HDL levels decreased. The increased lipid levels may explain, in part, the observation of increased vascular wall thickness, as measured by carotid ultrasonography, in this population. These factors all likely contribute to the increased incidence of cardiovascular mortality seen in patients with GH deficiency (2).
Muscle mass and muscle strength are diminished in GH-deficient patients. In the heart, these changes are manifested by a reduced left ventricular mass, decreased fractional shortening of cardiac myocytes, and decreased cardiac output. Such abnormalities may contribute to the striking decline in exercise capacity in this population. In one recent study, exercise capacity, as assessed by cycle ergometry was decreased by 20-25% compared to normal controls (3). Bone density is also known to be reduced in the GH-deficient patient. In a recent study, cortical bone density and spinal (trabecular) bone density were 2.8 and 1.5 standard deviations below the mean for age and sex matched controls (4).
Finally, patients with GH deficiency appear to have impaired psychological well being and potentially significant neuropsychiatric manifestations, such as lack of concentration and memory impairment. Self rating questionnaires consistently demonstrate reduced vitality, fatigue, social isolation and depression (5). However, it is unknown whether this impairment in psychological well being is associated specifically with GH deficiency or is due to another factor associated with hypopituitarism.
Recombinant Human Growth Hormone Therapy
Recombinant human growth hormone may become a novel therapeutic option for adults with acquired GH deficiency. Recent studies indicate that many of the metabolic and psychological abnormalities associated with GH deficiency can be reversed with GH replacement, even at low doses which are not associated with side effects.
Body Composition
GH therapy results in profound changes in body composition: fat mass is reduced while lean body mass increases. Growth hormone, at the relatively low dose of 0.003 mg/kg was shown to normalize lean body mass over 6 months in 24 adults with GH deficiency (1). The improvement in lean body mass is associated with increased protein synthesis, muscle mass and muscle function. Total body fat mass also decreases after 6 months of GH administration. The decline in fat mass is most significant in visceral and trunk locations as compared to the arms, neck and legs, suggesting that GH replacement therapy will reverse the truncal redistribution of fat mass associated with GH deficiency and impact on cardiovascular risk (6).
Lipid Metabolism
GH replacement in adults may have a beneficial effect on lipids. In a recent study, it was reported that short courses of GH reduced LDL cholesterol and this reduction correlated with increased mRNA expression of the LDL receptor in the liver (7). The potential benefit of this interaction has yet to be investigated in longer term clinical trials, but it must be noted that dramatic changes in serum lipid levels are not consistently seen with GH administration.
Bone Density
The potential role of GH in the maintenance of the skeleton has recently been investigated. GH is known to stimulate osteoblast proliferation and thymidine incorporation in vitro. Furthermore, GH stimulates systemic and local production of Insulin Like Growth Factor I, another known bone mitogen. In a recent study, GH replacement was shown to increase significantly bone Gla-protein, a sensitive indicator of osteoblast function (8). Less consistent changes in bone density have been demonstrated with GH administration. However, in a recent study using the sensitive techniques of quantitative tomography and single photon absorptiometry, significant increases of 5% and 4% were demonstrated in spinal and cortical bone density over 12 months of therapy in GH-deficient adults (4). It thus appears that GH administration may act to reverse the osteopenia present in the GH-deficient patient.
Cardiovascular Function
Improvements in exercise capacity and cardiac function have been demonstrated among GH-deficient patients receiving GH replacement in several recent studies. Such patients show increased oxygen uptake and power output during cycle ergometry associated with increased skeletal muscle mass and improved cardiac function. Echocardiography has shown that left ventricular mass index, fractional shortening and fiber shortening velocity all improve after 6 months of low dose GH therapy (8).
Side Effects Associated with Low-Dose GH Replacement
The dose of rhGH is an important consideration in the therapy of acquired GH-deficiency. Large, pharmacological doses of GH are often associated with the clinical sequelae of GH excess, including fluid retention and hypertension. However, increasingly smaller, physiological, doses of rhGH are currently being used for replacement in GH- deficient patients without such sequelae. At a dose of 0.03 mg/kg/week, Bengtsson et al. demonstrated only minor side effects including fluid retention and mild arthralgias in the majority of patients but did report carpal tunnel syndrome in one patient (6). In all cases, further reduction of the GH dosage resulted in amelioration of side effects. In another recent study in which a smaller dose of GH was used, 0.01 mg/kg was administered three times per week without any reported side effects (8). It remains unknown, however, whether chronic administration of GH at doses which keep IGF-I levels within the normal range will also improve key metabolic variables.
Future Directions
Growth hormone deficiency is an important cause of excess morbidity and even mortality. Evidence from a number of smaller studies indicates that GH replacement will improve body composition, lipid metabolism, bone density, cardiovascular function and psychological well being. Important issues remaining are the precise clinical definition of partial vs. complete GH deficiency in such patients and clarifying the best tests to make this diagnosis. In addition, it is unclear whether some of the observed beneficial effects reflect pharmacological GH therapy rather than physiologic GH replacement. Nevertheless, it is apparent that small doses, unassociated with sequelae of GH excess, may suffice to achieve the desired metabolic results. Definitive recommendations on dosage and the long term effects of GH therapy, particularly on cardiovascular morbidity and mortality, will be determined by the prospective studies now underway at the MGH and other centers around the country.
