Feeling flat, slow, or just not yourself is easy to put down to stress or getting older. Most of the time, there is a measurable reason in your blood. This is a guide to the hormone symptoms in men that carry a signal, and how to find what is actually behind them.
Men tend to wait. The energy is gone for months, the gym sessions feel heavier than they used to, motivation has flattened, and the conclusion you reach is "I am just stressed" or "I am getting older." Both can be true. Neither is the full picture.
Underneath those vague symptoms there is almost always a pattern in blood. Testosterone, SHBG, thyroid output, vitamin D, ferritin, and metabolic markers like HbA1c and insulin shape how you feel each day. The question is rarely whether something is measurable. It is which markers to look at, and how to read them as a system rather than a single number.
Why a single normal result can mislead
Two things make standard testing unreliable for men exactly when it matters most.
The first is timing. Testosterone follows a strong daily rhythm. In men aged 30 to 40, levels at 4 p.m. run about 20 to 25 percent below their 8 a.m. value (Brambilla et al., 2009). In that same study, half of the younger men with at least one low afternoon reading had completely normal levels at every morning visit. An afternoon draw can move you across the diagnostic line without anything actually changing.
The second is what gets measured. Total testosterone is the number most often ordered, but most of it is bound to SHBG (sex hormone-binding globulin) and is not biologically available. Endocrine Society guidance recommends that men with borderline totals, or anything that shifts SHBG, also have free testosterone measured (Bhasin et al., 2018). Without it, total testosterone can sit mid-range while the active fraction is low.
Then there is age. Long-running data from the Baltimore Longitudinal Study of Aging show a slow, steady decline in total and free testosterone with age, independent of illness or medication (Harman et al., 2001). Knowing your trajectory matters more than knowing a single value.
Take-away. A normal reference range tells you whether you are obviously ill. It does not tell you whether you are running well.
Why morning testing matters
Testosterone in younger men can run 20 to 25 percent lower in the afternoon than at 8 a.m. The same man can land on either side of the reference line depending on the hour.

Illustrative, not patient data. Same man, same day: a morning draw can sit above the line while an afternoon draw falls below it. Aware Male Hormones bookings run from 7 to 10 a.m. so your result reflects your biology, not the clock.
Hormone symptoms in men, symptom by symptom
The clusters below mirror how men usually describe what has changed. If you are in more than one, that is normal, and a broader panel almost always tells you more than testing a single number.
Persistent low energy and fatigue
If your default has shifted from "fine" to "tired," thyroid, ferritin, vitamin D, blood sugar, and inflammation are the first markers to interrogate. Subclinical hypothyroidism, where TSH is high but the active thyroid hormones look normal, is associated with a higher risk of fatigue and low mood in a meta-analysis of more than 100,000 people (Tang et al., 2019). Vitamin D deficiency is the European winter default and worth ruling out before assuming hormones. If the picture points at energy production itself, our piece on cellular energy goes deeper.
What to check: Ferritin, TSH, vitamin D, HbA1c, hs-CRP, vitamin B12.
Holistic Advanced
Low motivation and mood changes
Drive is not just testosterone, but testosterone is part of it. A meta-analysis of 27 trials in nearly 1,900 men found that testosterone treatment was associated with a reduction in depressive symptoms, most clearly at higher doses (Walther et al., 2019). Total testosterone can look normal while the free fraction is low, which is why the panel reads total and free testosterone alongside SHBG, with thyroid and vitamin D in the same view.
What to check: Total Testosterone, Free Testosterone, Free Testosterone Index, SHBG, TSH, vitamin D.

Poor gym performance and slow recovery
If sets you used to grind through suddenly feel grim and recovery has stretched, the pattern is rarely one marker. Testosterone supports muscle: a dose-response trial in healthy men showed that fat-free mass and strength rise in step with testosterone levels (Bhasin et al., 2001). Ferritin and iron support oxygen delivery, magnesium supports muscle function, and a quietly raised hs-CRP can mean low-grade inflammation is competing with adaptation.
What to check: Total Testosterone, Free Testosterone, Free Testosterone Index, Ferritin, magnesium in whole blood, hs-CRP.

Lower drive and libido
Libido in men is more sensitive to free testosterone and SHBG than to total testosterone alone. In the Testosterone Trials, a large set of randomised trials in older men with low levels, testosterone treatment improved sexual function compared with placebo (Snyder et al., 2016). Prolactin, LH, and FSH round out the picture and help locate where the signal is coming from. This is the cluster where a morning draw matters most.
What to check: Total Testosterone, Free Testosterone, Free Testosterone Index, SHBG, Prolactin, LH, FSH.

Brain fog and concentration issues
Testosterone is the usual scapegoat here, but it is often the wrong one: in the Testosterone Trials, treatment did not improve memory or cognition in older men with low levels (Resnick et al., 2017). That points the search toward thyroid, vitamin B12, vitamin D, blood sugar, and inflammation. A slowly drifting HbA1c in particular can flatten focus across the working day.
What to check: TSH, free T3, vitamin B12, vitamin D, HbA1c, hs-CRP.
Holistic Advanced
Weight gain and metabolic sluggishness
Insulin resistance and testosterone are tightly linked. A study using insulin sensitivity clamps showed that as insulin resistance rises, the testicular response weakens and testosterone falls, with the effect appearing at the level of the testis rather than the pituitary (Pitteloud et al., 2005). That makes metabolic markers part of the hormone conversation, not separate from it. If blood sugar is the theme, our glucose strategies guide is a good next read.
What to check: HbA1c, Fasting Glucose, Insulin, HOMA-Index, Testosterone, SHBG, Triglycerides.
Holistic Advanced or Sugar Metabolism
Hair thinning
Pattern hair loss in men is largely genetic and androgen-mediated, but diffuse thinning is often a nutrition and thyroid story. A review of micronutrients in non-scarring hair loss points to iron, vitamin D, zinc, and B vitamins as the most common modifiable contributors (Almohanna et al., 2019). Ferritin and TSH cover the rest.
What to check: Ferritin, Iron, vitamin D, TSH, Testosterone.
Holistic Advanced or Male Hormones Test
Take-away. Read your symptoms as a cluster, then pick the panel that covers it. Most men sit in more than one.
The numbers you do not test are the ones that surprise you.
Why SHBG matters as much as testosterone
Most testosterone in blood is bound to SHBG and is biologically inactive. Two men with the same total testosterone can have very different free testosterone, depending on their SHBG.

Not sure which test fits? Start here
If your symptoms are libido, drive, mood, or recovery, the Male Hormones Test is the right starting point. It covers total and free testosterone, the Free Testosterone Index, SHBG, oestradiol, prolactin, LH, FSH, and DHEA-S. Sampling runs 7 to 10 a.m. so the daily rhythm does not skew the result.
If symptoms span several clusters, or this is your first comprehensive blood test, Holistic Advanced gives the broadest baseline across thyroid, iron, blood sugar, lipids, kidney, liver, inflammation, vitamins, and minerals. If you want a lighter first check, Holistic Core covers the core risk markers and basic thyroid function.
If weight, energy crashes, or metabolic concerns dominate, the metabolic markers like HbA1c, fasting glucose, and insulin sit inside Holistic Advanced, or you can add the focused Sugar Metabolism panel.
Take-away. Most men find more answers in one broad panel than in chasing a single hormone. Start wide, then go deep where the numbers point.
Recommended starting point
Male Hormones Test
A nine-marker hormone profile for men navigating energy, drive, recovery, mood, or body composition changes that may be hormonally driven. Includes both total and free testosterone for a complete picture.
Sampling restricted to 7 to 10 a.m. for a reliable result.
Hormone symptoms in men, frequently asked
Why does the Male Hormones Test require a 7 to 10 a.m. appointment?
Testosterone follows a strong daily rhythm. In men aged 30 to 40, levels can run 20 to 25 percent lower at 4 p.m. than at 8 a.m., so a morning measurement is the only reliable baseline. Half of younger men with at least one low afternoon reading had completely normal levels at every morning visit. Booking outside the morning window risks a result that does not reflect your actual status.
My GP said my testosterone is normal. Why might I still feel low?
Total testosterone alone can miss the picture. SHBG, the protein that binds testosterone in blood, decides how much is biologically active. When SHBG runs high, total testosterone can look fine while free testosterone or the Free Testosterone Index is low. Endocrine guidance recommends free testosterone testing in men with borderline totals or altered SHBG, and the Aware Male Hormones Test includes both.
Which Aware test fits my symptoms best?
If your main complaints are libido, drive, mood, or recovery, the Male Hormones Test is the right starting point. For broad fatigue, brain fog, or a general baseline, Holistic Advanced covers thyroid, ferritin, vitamin D, inflammation, and blood sugar, while Holistic Core is the lighter option. If weight and metabolic sluggishness dominate, those markers sit inside Holistic Advanced or the focused Sugar Metabolism panel. If symptoms span several clusters, start with Holistic Advanced.
Can insulin resistance lower my testosterone?
Research using insulin sensitivity testing shows that as insulin resistance rises, the testicular response weakens and testosterone falls, with the effect appearing at the level of the testis. Improving insulin sensitivity through training, weight, and sleep often supports testosterone over time. Testing HbA1c, fasting insulin, and HOMA-Index alongside testosterone gives the full picture.
Is testosterone supposed to fall as I age?
Some decline is expected. Long-running data show a slow downward trend in total and free testosterone with age, independent of disease and medication. What matters is the trajectory, the absolute level, and whether free testosterone and SHBG are in proportion. A baseline reading in your 30s gives you something to compare against later. Results are best discussed with a healthcare professional.
