Testing Methods

Blood Testing

  • Testosterone levels checked
  • Growth hormone markers tested
  • EPO detected
  • Testosterone/Epitestosterone ratio analyzed

Urine Testing

  • Most common method
  • Detects metabolites of steroids
  • Can detect for weeks/months after use

Longitudinal Biological Passport

  • Tracks athlete's hormone levels over time
  • Abnormal changes trigger investigation
  • More sophisticated than single tests

---

Detection Windows (How Long Steroids Show Up)

SteroidDetection Window
Testosterone (oral)2-4 hours
Testosterone enanthate2-3 months
Testosterone propionate2-3 weeks
Trenbolone4-5 months
Nandrolone12-18 months
Boldenone4-5 months
Stanozolol2-3 months

Famous WADA Cases

Theresa Ruth Anderson (Olympic athlete)

  • Tested positive for boldenone
  • Claimed contamination (never proven)
  • Received 2-year suspension
  • Competed professionally after

Marion Jones (Olympic sprinter)

  • Tested positive for THG (designer steroid)
  • Received 2-year ban
  • Stripped of 5 Olympic medals
  • Admitted to steroid use years later

---

Summary

Key Facts:

  • ALL anabolic steroids prohibited by WADA
  • Testing is year-round for Olympic athletes
  • Failed test = 4-year ban (first offense)
  • Legitimate medical use requires TUE approval
  • Detection windows range from weeks to 18+ months

For competitive athletes: Steroids are not worth the risk. One positive test ends amateur career and can affect professional prospects.

For non-competitive athletes: No WADA testing in most bodybuilding/powerlifting competitions, so testing is not a concern.
