Topic: Blood tests for bodybuilders using higher testosterone dosages and other products.
Context: Many doctors don't monitor bodybuilders due to the stigma around performance-enhancing substances. It's crucial for bodybuilders to monitor their blood tests to minimize side effects and maximize muscle growth and fat burning.
Case Study 1: High Testosterone Dosage
Subject: A bodybuilder using high testosterone dosages.
Testosterone Levels: Extremely high (2,968 ng/dL), well above the normal range (250-1,100 ng/dL).
Free Testosterone: Also high, indicating potential side effects.
Lipid Panel: LDL cholesterol within normal limits, but HDL (good cholesterol) is low, which is a concern.
Liver and Kidney Function: Generally good, but high protein intake is evident.
Blood Sugar and Electrolytes: Normal levels, indicating good health.
Dihydrotestosterone (DHT): High, which could affect libido, hair loss, or acne.
Complete Blood Count (CBC): Shows increased red blood cell production, a common effect of testosterone and anabolic steroids.
Estradiol and Its Effects
Estradiol Levels: Discussed in relation to bone health, sex drive, and cognitive function.
Misconceptions: Many bodybuilders aim to lower estradiol, but it's essential for balancing testosterone effects.
Role of Estradiol: Protects the heart and enhances testosterone effects. Blocking it can be counterproductive.
IGF-1 and Growth Hormone
IGF-1 Levels: Normal for the subject, indicating healthy growth hormone metabolism.
Bodybuilding Impact: Higher IGF-1 levels are common in bodybuilders, especially those using growth hormone supplements.
Kidney Function and Liver Enzymes
Kidney Function: Good kidney function indicated by low cystatin C levels and high eGFR.
Liver Enzymes: Elevated AST and ALT levels likely due to intense workouts, not liver toxicity.
Iron Metabolism and Ferritin
Iron and Ferritin: Normal levels, but many bodybuilders experience lower ferritin due to increased iron usage in red blood cell production.
Importance of Monitoring: Regular checks for iron and ferritin levels are recommended.
Prolactin and Thyroid Function
Prolactin Levels: Normal, but high levels can cause issues like erectile dysfunction.
Thyroid Hormones: TSH, T3, and T4 levels within normal ranges, indicating healthy thyroid function.
Case Study 2: Lower Testosterone Dosage
Testosterone Levels: Lower than the first case (1,200 ng/dL).
Hemoglobin and Hematocrit: Elevated due to testosterone use, even at lower doses.
Thyroid Function: Normal TSH, T3, and T4 levels.
Iron and Ferritin: Within normal range, but on the lower side.
DHEA and Insulin: Normal levels, indicating good health.
Conclusion
Overall Health: Both subjects show good health indicators despite high testosterone usage.
Recommendations: Regular monitoring of blood tests is crucial for bodybuilders, especially for testosterone, estradiol, liver enzymes, kidney function, and iron levels.

Understanding Your Hormones
Estradiol (E2)
A form of estrogen produced from testosterone. Important for bone health, mood, and libido.
Too high can cause side effects; too low can affect well-being.
DHT
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth,
prostate health, and masculinization effects.
Free Testosterone
The biologically active form of testosterone not bound to proteins.
Directly available for cellular uptake and biological effects.
