Introduction
In 1997, Sports Illustrated asked 198 aspiring US Olympians,
“Would you take a banned performance enhancing substance if you were guaranteed to win and not get caught?”
98% said “YES”

Then, when asked,
“Would you take the same undetectable substance if it would contribute to winning every competition for 5 years, then result in death?”
Over 50% still said
“YES!!!”

CREATINE
Regeneration of muscle ATP store
Cr + Ph = Cr-Ph; Cr-Ph + ADP + H+ = Cr + ATP
Adverse Effects:- (1) Muscle cramps
(2) Interstitial nephritis

STIMULANTS
Increased catecholamine Increased lipolysis
CNS stimulation Improved respiratory function
Increased alertness
Allays fatigue

DIURETICS
Any diuretic may be used
Mechanism of Action:- (1) Body weight reduction (2) Elimination of other doping agents through urine
Adverse Effects:- (1) Dehydration (2) Cardiac arrhythmias
