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.
