You're not imagining it, and you don't have to figure it out alone
If you've been feeling flat, tired, foggy or unmotivated, your blood results can hold real clues. The problem is most men are handed a page of numbers with "everything's normal" and no explanation, or they end up piecing together theories from forums at midnight.
This guide explains, in clear, jargon-free terms, the markers worth understanding and what each one is telling you. It won't diagnose you or tell you what to take, because that's your doctor's job. What it will do is help you walk into that appointment informed, asking the right questions, instead of being brushed off.
How to use this guide
- Read it before you get your bloods done, so you know what to look at.
- Use the "ask your doctor" prompts under each marker.
- Bring the questions checklist to your appointment.
- Remember: numbers are only half the picture. Your symptoms and lifestyle matter just as much.

How to Prepare for a Blood Test
A blood test is only as useful as the conditions it's taken under. A few simple things can make your results more meaningful and comparable over time. These are general points, and the right approach can differ from person to person, so confirm the details with your healthcare provider.
Test in the morning
Several hormones, especially testosterone and cortisol, follow a daily rhythm and peak in the morning. The guide suggests aiming for a sample within 2 hours of your normal waking time for an accurate reading.
Consider fasting beforehand
The guide notes that fasting (12 hours is best, water only) gives accurate glucose, insulin and lipid results, because these markers fluctuate after food intake. Whether fasting is needed can depend on the test and the person, so follow the instructions from your healthcare provider or lab.
Be consistent
Test under the same conditions each time (time of day, fasted or not, similar sleep and training) so you are comparing like with like.
Mention recent factors
Heavy training, illness, poor sleep, alcohol or big stress in the days before can all move your numbers. Note them so they can be taken into account.
Where to get tested
You can ask your primary care provider to order a panel, or use a direct-to-consumer pathology service where you order your own tests. Either way, keep a copy of every result. One of the most valuable aspects of bloodwork is tracking trends over time.
Understanding Hormone and Testosterone Markers
What each marker measures, why it matters, and what to raise with your doctor.
Total Testosterone
The headline number: the total amount of testosterone in your blood. It is influenced by age, sleep, body fat, stress, supplements, illness and the time of day you test.
Ask your doctor: Is this result related to my symptoms, and should it be repeated (morning, fasted) to confirm? Would I benefit from meeting with an endocrinologist?
Free Testosterone
This number indicates the amount of testosterone freely circulating, not bound to carrier proteins. Testosterone balance is delicate, and the ratio of total to free testosterone provides insight into testosterone metabolism, transport and utilization.
Ask your doctor: How does my free level compare to my total, and what does that suggest?
SHBG
The protein that binds testosterone. High SHBG can leave less free testosterone available, and low SHBG the opposite. It is affected by thyroid, insulin and blood sugar, and liver health.
Ask your doctor: Is my SHBG affecting how much testosterone is actually available to me?
LH and FSH
Signaling hormones from the pituitary gland. They help a doctor work out where a hormone issue might originate: the testes themselves, or the brain and pituitary that signal them.
Ask your doctor: Do my LH and FSH point to where the issue is coming from?
Estradiol (E2)
Yes, men need some estrogen too. It contributes to libido, mood, bone density and body composition. It is about balance, not simply "high" or "low", but the relationship between estradiol and other hormones.
Ask your doctor: Is my estradiol in healthy balance with my other hormones?
Prolactin
A pituitary hormone that, when elevated, can affect libido and other hormones. Worth checking as part of a full picture.
Ask your doctor: Should prolactin be investigated further given my symptoms?
Understanding Metabolic and General Health Markers
These markers shape how you feel day to day, and they interact with your hormones more than most men realize.
HbA1c and Fasting Glucose
Your blood sugar control over recent months. Insulin resistance and high blood sugar can drain energy levels and are tightly linked to hormone and metabolic health. HbA1c provides an average of your sugar levels, while glucose provides a snapshot on the day. Together they provide important information on overall metabolic health.
Ask your doctor: Do these suggest I am insulin resistant?
Complete Blood Count (CBC)
A broad picture of your red and white blood cells. It includes hematocrit (how much of your blood is made up of oxygen-carrying red cells) and how this may affect viscosity, or thickness. It can also show possible signs of infection, inflammation, autoimmunity or anemia.
Ask your doctor: Am I anemic? Do I have "thick blood"? Is my immune system functioning appropriately?
Cholesterol, Lipids and ApoB
Lipids include HDL, LDL, triglycerides and ApoB. These are cardiometabolic markers used in determining risk of cardiovascular disease, heart attacks and strokes. An important area to focus on when aiming for optimal health and longevity.
Ask your doctor: What cholesterol markers can I improve to lower my risk of cardiovascular disease?
Vitamin D, Ferritin and Iron
Common, fixable causes of fatigue and low mood. Low vitamin D and low iron stores (ferritin) can mimic or worsen many "low energy" symptoms. Ferritin also provides information regarding the level of inflammation in your body.
Ask your doctor: Are my vitamin D levels adequate? Could my high ferritin be indicative of inflammation?
Thyroid Function
An underactive thyroid can produce fatigue, weight gain, low mood and brain fog. Symptoms are easily mistaken for something else, so it is always worth ruling in or out.
Ask your doctor: Could my thyroid be contributing to how I feel? Is it possible I have subclinical hypothyroidism?
Liver, Kidney Function and PSA
Baseline organ health markers that give important context. For older men, a PSA reading is a useful prostate baseline to discuss.
Ask your doctor: Are my organ function baselines healthy, and is PSA relevant for my age? Are there any trends over time that I need to be aware of?
Lifestyle Factors That Influence Your Health
Bloodwork is only half the picture. For most men, how they feel is driven as much by daily habits as by any single marker. These are the levers you control today.
Sleep
The guide describes sleep as the single biggest lever for hormones, energy and mood, and notes that poor sleep alone can suppress testosterone.
Resistance training
Lifting weights supports hormones, body composition, mood and insulin sensitivity.
Body composition
Excess body fat, especially around the middle, works against healthy hormone balance.
Nutrition
Enough protein, whole foods and adequate micronutrients underpin everything else.
Alcohol and stress
Both quietly drag on hormones, sleep and recovery when they pile up. The guide states there is no healthy amount of alcohol.
Medications
Some everyday medicines can affect your levels and may disrupt your hormones. It is worth reviewing them with your doctor.
The honest truth
Many men feel better by addressing sleep, training, nutrition and stress before anything else. Start there while you investigate the rest. It's not the exciting answer, but it is the most honest.
Questions to Ask Your Healthcare Provider
Take this list with you to your appointment.
- Are my results actually in context with the symptoms I'm experiencing?
- Should any results be repeated under proper conditions (morning, fasted) to confirm?
- What might be driving how I'm feeling, and what's the most likely cause?
- Are there lifestyle or other factors we should address first?
- Do any markers need further investigation or referral to a specialist?
- What would you want to re-test, and when, to track progress?
When to Seek Medical Advice
Please book a proper medical appointment and don't rely on a guide like this if you're experiencing things such as:
- Significant or worsening fatigue, low mood or loss of interest in life
- Dramatic weight loss without trying
- Chest pain, breathlessness, or other concerning physical symptoms
- Any thoughts of harming yourself
- Symptoms that are getting worse, or simply worrying you
