Historical Significance Discovery and Synthesis
References
-Scientists in the 1930s discovered that anabolic steroids could facilitate the growth of skeletal muscle in laboratory animals
-This breakthrough led to abuse of these compounds by bodybuilders and weightlifters and then by athletes in other sports.
Adminstering Anabolic Steroids
-orally, injected intramuscularly, or rubbed on the skin when in the form of gels or creams
-these drugs are often used in patterns called cycling, which involves taking multiple doses of steroids over a given time period, stopping for a period, and then beginning again.
-Users combine several different types of steroids in a process known as stacking; the belief is that a variety of steroids will produce an effect on muscle size that is greater but side effects will be decreased
-pyramidding an another common practice in which the user takes the highest level of steroid in the middle of a cycle and then decreases servings towards the end of the cycle
The effects
- ability to train harder.
- build muscle mass.
- help cut down on recovery time after strenuous exercise
Addictive Nature
-User can become psychologically dependent long before he or she becomes physically dependent
-Withdrawal symptoms including: headaches, lethargy and depression are common
Steroid Law
-Anabolic steroids are Class C drugs that can only be prescribed by a doctor.
-Importation of steroids is legal as long as they are only for personal use
-Importation with the intent to distribute is punishable by up to 14 years in prison

Ruzicka Butenandt
Butenandt and G. Hanisch published a paper describing “A Method for Preparing Testosterone from Cholesterol.”
Ruzicka and A. Wettstein, announced a patent application in a paper “On the Artificial Preparation of the Testicular Hormone Testosterone.”
Their independent partial syntheses of testosterone from a cholesterol base earned Butenandt and Ruzicka each a share of the 1939 Nobel Prize for Chemistry.

Back
Near the end of his life, he made and injected an elixir that was a liquid extract made from the testicles of guinea pigs and
dogs. Brown-Sequard said his formula increased his physical strength and intellectual prowess, relieved his
constipation, and even lengthened the arc of his urine.

Did heightened testosterone levels contribute to history’s villains?
Napoleon Complex
-The Napoleon complex is named after French Emperor Napoleon Bonaparte. Napoleon overcompensated for his short height (lack of testosterone) by seeking power, war and conquest.
Baby Boom
-The “golden age of testosterone reseach” coincides with the increase in newborn’s between 1946 and 1964
-Testosterone was synthetized as a fertility drug

In 1927, Koch and his student, Lemuel McGee, derived 20mg of a substance from a supply of 40 pounds of buffalo testicles that, when administered to castrated roosters, pigs and rats, remasculinized them.
1934- Ernst Laquer

Research proved that this newly synthesized compound — testosterone — was a potent multiplier of muscle, strength, and wellbeing.
