Testosterone (and other anabolic steroids) – Why it matters for track & field




What Why it gives an edge in athletics


↑Protein synthesis Builds muscle fibers faster → more power, sprint speed, and better shot‑put/throw performance.


↓Recovery time Less damage after hard training; athletes can train harder & more often without over‑reaching.


Increased red‑blood‑cell mass (via erythropoietin stimulation) More oxygen delivered to working muscle → higher endurance and faster recovery from fatigue.


Enhanced nerve–muscle coordination Improves technique in technical events (e.g., hurdles, pole vault).


Because of these effects, even a single dose can produce measurable performance gains for up to several weeks—often the window that athletes exploit in doping cycles.

2. How does the athlete’s body "know" it has taken a drug?



2‑1. What the athlete experiences




No obvious side‑effects – many anabolic agents (e.g., nandrolone, stanozolol) are designed to be relatively non‑toxic at low doses.


A "boost" in strength or endurance – due to altered muscle metabolism, improved oxygen delivery, and reduced fatigue.


Changes in mood or appetite – e.g., increased aggression, decreased anxiety, or an enhanced sense of well‑being.



Because these are subjective feelings rather than clear physiological signs, the athlete often cannot objectively confirm drug ingestion. That’s why athletes rely on biochemical tests to verify doping status.


3. The "Test" that Determines If You’re Clean or Not



a) Types of Tests



Test What it Measures Typical Sample


Blood (e.g., Athlete Biological Passport) Hemoglobin, reticulocyte counts, RBC indices Venous blood draw


Urine Testosterone/epitestosterone ratio, presence of synthetic steroids Urine collection bottle


Hair / Saliva Long‑term drug exposure, recent ingestion Hair strand or saliva sample


Tissue Biopsy (rare) Localized drug deposition Muscle biopsy



b) The Testing Process






Sample Collection – Performed by trained officials under controlled conditions.


Chain of Custody – Every handover is logged to prevent tampering.


Laboratory Analysis – Samples are sent to accredited labs (e.g., WADA‑approved).


Results Interpretation – Analysts compare detected substances against reference libraries and thresholds.


Reporting – Findings are reported to relevant authorities or governing bodies.




c) Thresholds & Legal Limits



Substance Threshold Implication


Testosterone 0.2 ng/mL (example) Above → Possible doping


EPO 10 pg/mL Above → Possible doping


HGH Note: Thresholds vary by substance, laboratory, and governing body.

4. How to Stay Informed & Protect Yourself



4.1 Regular Health Check‑ups



Annual blood tests: CBC, liver enzymes, kidney function.


Monitor hormone levels if you suspect issues.




4.2 Educate Yourself About Supplements



Verify ingredients and dosages from reputable sources.


Watch out for unapproved substances (e.g., anabolic steroids).




4.3 Report Suspicious Findings



If a lab test shows abnormal results, discuss with your physician promptly.


Consider second opinions if results seem inconsistent.




4.4 Maintain a Healthy Lifestyle



Balanced diet rich in vitamins & minerals.


Adequate sleep and regular exercise.


Stress management techniques (meditation, yoga).







Final Takeaway


Blood tests are powerful tools that can detect hidden health problems, including serious conditions such as cancer or infections. If you suspect an issue—especially one that could involve blood or a serious disease—consult your doctor for a comprehensive evaluation. Early detection through appropriate testing is key to successful treatment and better outcomes.
