PERFORMANCE ENHANCING
DRUGS
3
Performance-Enhancing Drugs
Anabolic Steroids
Description
Drugs derived from testosterone and approved for
medical use, but often used by athletes to increase
musculature and weight.
4
Performance-Enhancing Drugs
Anabolic Steroids
Claims  May enhance performance and improves physical
appearance.
 Reported to increase lean muscle mass, strength, and
the ability to train longer and harder.
5
Performance-Enhancing Drugs
Anabolic Steroids
Risks  Liver tumors, jaundice, fluid retention, high blood
pressure, severe acne, aggression and other
psychiatric side effects.
 Men: Shrinking testicles, reduced sperm count,
infertility, baldness, and development of breasts.
 Women: growth of facial hair, changes in or
cessation of the menstrual cycle, enlargement of the
clitoris, and deepened voice.

Androstenedione
produced by:
1- the ovary, testes, and the adrenal cortex,
2-is a prohormone for both estrogen and testosterone..
3- Androstenedione supplementation has become popular
with male athletes because they believe they will be more
powerful.
4-Research shows no measureable effect on free or total
testosterone,
5-but HDL levels dropped and plasma estrogens rose.
6- No measurable effect has been noted on athletic
performance.

GYNECOMASTIA
These pictures are the “BEFORE” (left) and “AFTER” (right)
pictures of a man that had surgery to correct his case of
gynecomastia. I’m sure he thought “It won’t happen to me.”
as well! Think about it before you choose to take P.E.D.!
9
Performance-Enhancing Drugs
Androstenodione
Claims
Improves testosterone concentration, increases
muscular strength and mass, helps reduce body
fat, enhances mood, and improves sexual
performance.
10
Performance-Enhancing Drugs
Androstenodione
Risks  Breast enlargement, increased risk of
cardiovascular disease and pancreatic cancer
in men, acne, male pattern baldness, and a
decrease in “good” (HDL) cholesterol.
 In women, high testosterone levels can cause
increased body hair, deepening of the voice,
and other male characteristics.
11
RISKS OF P.E.D.
 Steroid induced acne
 Anti-hypertensive behaviors
 Hypertension or fatigue
 Chronic gonadotrophin
 Increased level of female hormones in a man’s body
 Testicular atrophy
 Induced gynecomastia
 Presence of abnormally large breasts in men

12
SYMPTOMS OF P.E.D. USE

Stimulants
Description: A group of synthetic or plant-derived drugs
that increase alertness and arousal by stimulating the
central nervous system.
Medical Uses:
Short-term treatment of obesity,
narcolepsy, and hyperactivity in children No medical use
for methamphetamine
Method of Use: Intravenous, intranasal, oral, smoking
Types of Stimulant Drugs
1- Cocaine Products
 Cocaine Powder (Generally sniffed, injected, smoked on foil)
 “Crack” (smoked)
19
Types of Stimulant Drugs
2- Amphetamine Type Stimulants (ATS)
 Amphetamine
 Dexamphetamine
 Methylphenidate
 Methamphetamine

Methamphetamine vs. Cocaine
 Cocaine half-life: 1-2 hours
 Methamphetamine half-life: 8-12 hours
Cocaine and the amphetamines have very similar effects on
mood, patterns of abuse, the type of dependence produced,
and their toxic effects.
 Cocaine paranoia: 4 -8 hours following drug cessation
 Methamphetamine paranoia: 7-14 days
 Methamphetamine psychosis - May require medication/hospitalization
and may not be reversible
 Neurotoxicity: Appears to be more profound with amphetamine-like
substances, rapid formation of lesions

Cocaine Hydrochloride
 Crystalline white powder
 Snorted in “lines” of 10-35 mg each
 Adulterated w cheap local anesthetics,
stimulants, and inert white powders
 Yields moderate to high blood levels
 Gradual onset of effects at 15-20 min with peak at
30-60 min
26
Cocaine Hydrochloride:
Intravenous Administration
 Soluble in water
 Peak blood levels achieved instantaneously
 Rapid onset, brief duration, intense “crash”
 Rapid development of compulsive use pattern
 “Speedball” when mixed with heroin to cushion the
“crash”
27
Cocaine: Mechanism of
CNS Action
 Increases the synaptic concentration of dopamine and
Norepinephrine by preventing its reuptake
 Dopamine agonists/replacements have not proved
therapeutically useful in addicts
