01 — The epidemic
Men in their 20s and 30s today carry the testosterone of a 70–80-year-old from the 1970s.
The fall is close to linear, it shows no sign of flattening, and no European government measures it. The consequences are wide: insulin resistance, type 2 diabetes, muscle loss, osteoporosis, low mood and premature ageing — in the young as well as the old.
Fall in mean total testosterone since the 1970s baseline — roughly 1% per year.
nmol/L: the 1970s/80s elite mean at age 20 against today's average 20-year-old.
Burnout, depression, prediabetes, early sarcopenia — separate diagnoses for one unmeasured cause.
How good it used to be.
Total and free testosterone across adult life, historical elite cohorts against today's average. Nearly every symptom filed under "getting older" sits in the gap between these lines.
Total testosterone (nmol/L)
Free testosterone (pmol/L)
The reference point has quietly moved.
Laboratory "normal" ranges are drawn from a declining population. Measured against the 1970s cohort, today's average man sits where a deficient man once sat.
| Period | Total T average | Total T top 10% | Free T average | Free T top 10% |
|---|---|---|---|---|
| 1970s (baseline) | 29 nmol/L | 35 – 45+ nmol/L | 520 pmol/L | 600 – 750 pmol/L |
| 1980s | 26 nmol/L | 32 – 40 nmol/L | 480 pmol/L | 550 – 680 pmol/L |
| 2026 (present) | 20 nmol/L | 25 – 33 nmol/L | 360 pmol/L | 450 – 580 pmol/L |
Where do your symptoms sit?
Symptoms correlate far more strongly with free testosterone than with total testosterone — the EMAS finding that most standard consultations still miss.
High energy, sharp cognition, optimal muscle mass, robust libido and daily erections.
Stable energy, maintained muscle mass, normal metabolic profile, functional libido.
Mild fatigue, brain fog, slower recovery, belly fat tendency, fluctuating libido.
Severe fatigue, brain fog, muscle loss, insulin resistance, loss of libido and erections.
Are you experiencing these markers?

The international symptom test
Two minutes, answered instantly. It maps your symptoms against the domains that track free testosterone.
Take the test nowFinger-prick test, LC-MS/MS
If the test indicates low T, confirm it. Our at-home finger-prick kit is analysed by mass spectrometry and tells you exactly where total and free testosterone sit. €75.

After the analysis a consultation is set up where the doctor concludes on your symptoms and your bloodwork — and issues a prescription where therapy is indicated.

Mediocre results from restrictive Scandinavian standard therapy?
If your protocol peaks around 20 nmol/L and crashes to 10–15 before the next injection, you feel the trough more than the treatment. We offer more optimal testosterone forms with minimised troughs — thin, additive-free preparations without allergenic or inflammatory carrier oils, given with the finest subcutaneous insulin needles. Creams are of course also available.

Women lost the same baseline.
Oestrogen falls up to 90% through menopause while testosterone falls roughly 50% — reshaping the ratio that governs bone density, muscle tone, cognition and libido. See the female charts, the free testosterone symptom bands and the micro-dosing protocol.
Women's hormonal status →What changes at optimal levels.
Targeting the upper optimal spectrum — rather than merely clearing a lowered laboratory floor — is where the documented clinical benefit lives.
Visceral fat reduction
Testosterone directly inhibits abdominal lipid storage and enhances lipolysis. Belly fat shrinks where diet alone stalled.
Muscle mass & bone density
Protein synthesis and myonuclear accretion scale with hormone level, reversing age-related sarcopenia and arresting bone loss.
Insulin sensitivity
Studies show up to a 32–35% increase in tissue glucose uptake in response to insulin — testosterone acts as a potent insulin sensitiser.
Diabetes remission
In long-term registries with up to 11 years of follow-up, approximately 34% of hypogonadal men with type 2 diabetes reached full remission.
Cognition & mood
Restored drive, concentration and emotional stability — the symptoms most often misattributed to burnout.
Cardiometabolic resilience
Physiologically high free testosterone protects against visceral fat, low-grade inflammation and insulin resistance.
