Frowned Upon

• Uneven playing field• “How [am I] supposed to compete when others were

taking PEDS?” –Jeff Cirillo, 2002

• Health Side Effects• Acne• Impaired liver function• Increase in estrogen• Male pattern baldness

• Sets poor example for children• Shortcuts• Young people (Under 21) should NOT take steroids.

Doping

• Steroids/HGH/Blood Doping/Stimulants• What do they do?• Make muscles grow faster• Harmful side affects to health• Reduce fatigue• Recover from injuries quicker• Most major sports have banned them

• But how does it really work?• How are we stopping them?

Steroids in Baseball

• Thomas Boswell, 1988• “The most conspicuous example of a

player [Jose Canseco] who has made himself great with steroids.” –CBS Late Night

• Truth without portfolio• Couldn’t publish this in a newspaper

• Beat Writers heard rumors, but could never whistle blow• Bob Nightengale, July 1995

• “Steroids Become an Issue…”Jose Canseco

Steroids

• Definition: Refers to a class of hormones with a classic poly-phenol ring structure.• Catabolic Steroids (glucocorticoids)• Produced in the adrenal cortex or made

synthetically. Various metabolic function use to treat inflammation.

• Anabolic Steroids• Synthetic steroid hormone that

resembles testosterone in promoting the growth of muscle.

Page 9: Testing of Performance Enhancing Drugs James Rosenberger September 22, 2014.

Anabolic Steroids

• “Contain a synthetically manufactured form of the hormone testosterone”• Primary male sex hormone• An enhanced rate of protein

synthesis leading to muscle accumulation• Reason why males carry more muscle

mass than women• 11mg per day vs ¼ mg per day.

Testosterone

(Simple) Biochemistry of Anabolic Steroids

• Testosterone binds to intracellular receptor site in cytosol• Form Receptor complex and it

migrates to cell’s nucleus• Attaches to cell’s DNA• Activates transcription of

specific genes• Increase synthesis of two

primary contractile proteins, actin and myosin

ANABOLICS, 10th edition, William Llewellyn

Human Growth Hormones (HGH)

• Naturally occurring protein hormone• Excessive amounts give user

benefits by stimulating• Protein synthesis for increased

muscle mass• Bone growth for stronger bones• Breakdown of fat cells

• Use of HGH has become increasingly popular due to the difficulty of detection

Human Growth Hormones (HGH)

• Important Side-Effects• Stress on liver and

kidney• Swelling in the limbs• Migraines and

Headaches• High blood pressure• Bloating• Arthritis-like symptons

• But what makes testing so difficult?

Human Growth Hormone Testing

Isoform Testing• At present, only blood tests have

found positive results• Natural HGH weighs 20 kDaltons• Synthetic HGH weighs 22

kDaltons• NFL & MLB: positive cutoff is 1.8• Downside:

• Short detection window (18-24 hours)

• 10,000 tests have been done since 2004 with only 14 positives.

HGH Testing

• A new method with LC-MS/MS is being tested• Measures IGF-1, Insulin-like

Growth Factor – 1• Blood test• IGF-1 is the response from an

active pituitary gland and a byproduct of HGH.

Liquid Chromatography

• Separation!• Stationary phase – Packed in column• Mobile phase – Solvent (based on polarity)

Mass Spectrometry

• LC Product fed in• Ionized• Electric Field is altered

• Light particles get curved too much

• Heavy particles ignore field

• Tolerances are hard to find as detectors measure m/z• Retention Time and m/z ratio

can narrow down search considerably

Page 17: Testing of Performance Enhancing Drugs James Rosenberger September 22, 2014.

T/E Ratio

• Testosterone/Epitestosterone• Epitestosterone is a byproduct

of testosterone• Normal ratio is 1:1• Positive test for NFL/MLB is 4:1• Carbon Isotope test follow up.• Pharmaceutical testosterone has

slightly more Carbon 12.

Concerns for Future

• Testing is expensive• Can we lower the price?• Use chemical reactions on

manufactured kits?• Avoid high priced machines

• Drugs are developing every year and finding a test will always lag behind• Lower tolerances, but avoid

false positives

Page 19: Testing of Performance Enhancing Drugs James Rosenberger September 22, 2014.

Real Life Examples

• Last week: NFL added HGH Testing into Drug Testing Policy• Possibly lower tolerances

• Olympians in Sochi• A passport of every drug test

they have had.• Gives testing facility a

comparison

• Drug Screening for Jobs
