Blood values for strength athletes
Blood values show your condition from the inside, past anything the mirror tells you. Training hard shifts some values for a while, muscle and liver markers among them. Look up a value and read its reference range. You also see when a result genuinely needs attention.

Erythrocytes (RBC)
Your red blood cell count is a direct indicator of how effectively your body delivers oxygen to muscles and organs. For men focused on vitality and physical performance, monitoring erythrocytes helps ensure you are operating at full capacity.
Estradiol (E2)
Estradiol (E2) is the primary estrogen in men, influencing bone density, libido, and cardiovascular health. While often associated with women, balanced estradiol levels are essential for men's wellbeing. Your healthcare provider can help interpret your results.
FSH (Follicle Stimulating Hormone)
Follicle-stimulating hormone (FSH) regulates sperm production and testicular function in men. It is produced by the pituitary gland and works alongside LH and testosterone. Abnormal levels may indicate issues with fertility or hormonal regulation worth discussing with your provider.
Ferritin
In men the ferritin level points in two directions, and both are often misread. A low ferritin in a man has no obvious explanation: the monthly blood loss that is the most common cause in women is absent here. A reduced store therefore always warrants investigation into where the iron is being lost, usually in the gastrointestinal tract. Conversely, a raised ferritin is often read as a well-filled iron store, when far more often it involves alcohol, fatty liver, excess weight or inflammation. Only with a raised transferrin saturation alongside does iron overload genuinely come into view.
Folate (Folic Acid)
Folate measures vitamin B9 levels in your blood. For men, adequate folate may support cardiovascular health, red blood cell production, and cellular repair processes that are important for maintaining energy and vitality.
Free T3 (Triiodothyronine)
Free T3 is considered the most active thyroid hormone and may play an important role in men's metabolism, muscle maintenance, and energy levels. Some healthcare providers suggest that optimal Free T3 can support male vitality and body composition.
Free T4 (Thyroxine)
Free T4 is the main hormone produced by the thyroid gland and may play an important role in men's metabolic rate, energy levels, and body composition. Some healthcare providers suggest that optimal T4 supports male hormonal balance and physical performance.
Free Testosterone
Free testosterone is the unbound fraction that directly fuels muscle growth, energy, libido, and mental sharpness in men. It may provide a clearer picture of your androgen status than total testosterone alone. Your healthcare provider can help evaluate your results.
GGT (Gamma-Glutamyl Transferase)
GGT is a highly sensitive liver enzyme particularly relevant for men's health. Alcohol consumption, high-protein diets, and certain supplements commonly used by men can significantly elevate GGT levels, making it an important marker for monitoring liver wellness.
Glucose (Fasting)
Fasting glucose is a fundamental metabolic marker. Stable blood sugar supports energy, focus, and body composition for men.
HDL Cholesterol
In men, HDL cholesterol is the value that responds most sharply to testosterone, and at the same time the value least is said about. The lower limit sits at 1.0 mmol/l, lower than in women, because men naturally have less HDL. What mainly pulls the value down is not your cholesterol intake but your waistline, your insulin sensitivity and the use of androgenic agents. That last one is the pattern to recognise: a lipid profile in which everything looks normal, except an HDL that has halved and an LDL that has climbed. This page explains when your HDL is genuinely too low, what you can do about it that demonstrably works, and how quickly the value recovers when androgens are stopped.
HIV 1/2 Antibody + p24 Antigen
The HIV Combo test is a fourth-generation test that detects both HIV p24 antigen and HIV antibodies simultaneously. This dual approach enables earlier detection compared to antibody-only tests, typically within two to six weeks after exposure.
HOMA-IR
HOMA-IR measures insulin resistance by calculating a score from fasting glucose and insulin levels. For men, monitoring insulin sensitivity is important for managing metabolic health, maintaining a healthy body composition, and reducing the risk of type 2 diabetes and cardiovascular disease.
Haptoglobin
A haptoglobin test measures the level of haptoglobin protein in your blood. Haptoglobin binds to free hemoglobin released from damaged red blood cells, and its levels can help assess whether red blood cells are being destroyed faster than normal.
HbA1c (Glycated Hemoglobin)
HbA1c reveals your long-term metabolic control. Stable blood sugar supports sustained energy, focus, and body composition management.
Hematocrit
In men, hematocrit is the value that shows first when red cell production changes. It describes how much of your blood consists of red cells. Testosterone actively drives that production. That is exactly why the male reference band sits above the female one. It is also why this value is monitored as standard under testosterone therapy. A raised hematocrit is not a diagnosis in itself. The question is always what pushes it up: dehydration, smoking, sleep apnoea, altitude or a hormonal cause.
Hemoglobin
Hemoglobin is the engine behind your body's oxygen delivery. For men focused on strength, endurance, and daily energy, tracking hemoglobin ensures your blood is fuelled for action and your vitality stays on point.
Hemoglobin Electrophoresis
Hemoglobin electrophoresis is a laboratory technique that separates and identifies different types of hemoglobin in your blood. It is primarily used to detect hemoglobin variants and diagnose inherited blood disorders such as sickle cell disease and thalassemia.
Hepatitis B Core Antibody
A Hepatitis B Core Antibody (anti-HBc) test detects antibodies produced in response to the core antigen of the hepatitis B virus. A positive result may indicate a current, past, or resolved hepatitis B infection and should be interpreted alongside other hepatitis B markers.
Hepatitis B Surface Antigen
A Hepatitis B Surface Antigen (HBsAg) test detects the presence of HBsAg in your blood, which is one of the earliest indicators of a hepatitis B infection. A positive result may indicate an active hepatitis B infection and should be evaluated by a healthcare professional.
Hepatitis C Antibody
A Hepatitis C Antibody (anti-HCV) test detects antibodies produced by the immune system in response to the hepatitis C virus. A positive result indicates exposure to the virus but does not distinguish between a current or past infection. Further testing is needed for confirmation.
Holotranscobalamin
Holotranscobalamin measures the earliest marker of B12 deficiency. For men, early detection of B12 depletion may help preserve energy levels, cognitive sharpness, and nervous system health before symptoms develop.
Homocysteine
Homocysteine is a cardiovascular risk marker. Keeping levels in check supports heart health, circulation, and overall male vitality.
IGF-1 (Insulin-like Growth Factor)
IGF-1 is a key growth factor that may influence muscle development, recovery, and overall vitality in men. Monitoring this marker can provide insight into your body's repair and growth capacity.
