Is Low Testosterone Limiting Your Performance?
- For high performers, suboptimal testosterone doesn’t just affect energy – it impacts every aspect of your competitive edge. These symptoms often creep up slowly, easy to dismiss as stress or overwork.
- Symptom 1: Crushing Fatigue
- Waking up exhausted despite quality sleep. Needing stimulants to function. That afternoon crash destroying your productivity.
- Symptom 2: Low Libido and ED
- Lost interest in sex. Weaker erections. Morning erections becoming rare. Affecting your relationship and confidence.
- Symptom 3: Brain Fog and Flat Mood
- Can’t concentrate. Forgetting details. Lost your drive and competitive fire. Operating at 60%.
- Symptom 4: Losing Muscle, Gaining Fat
- Training hard but results have stalled. Belly fat increasing despite strict diet. Strength declining year on year.
- Symptom 5: Poor Recovery
- Taking longer to recover from workouts. Sleep quality declining. HRV trending down. Never feeling fully recharged.
- Symptom 6: Lost Your Edge
- Performance declining. Can’t push as hard. Lost that relentless drive. Watching others overtake you.

FAQ’s
What is this testosterone calculator and how does it work?
This is a free, science-based screening tool using the clinically validated Androgen Deficiency in Aging Males (ADAM) questionnaire, which has 88% sensitivity for detecting low testosterone indicators. It assesses 10 key symptoms (e.g., low libido, fatigue, weaker erections) plus lifestyle factors like morning erections, sleep quality, alcohol intake, and resistance training. You answer yes/no questions and select options—it takes about 2 minutes—to generate a personalised risk score for suboptimal testosterone.
Does this calculator measure my actual testosterone levels?
No, this is not a blood test and does not provide exact testosterone levels (e.g., in nmol/L or ng/dL). It calculates a risk score based on symptoms and indicators to highlight if low testosterone may be affecting your energy, mood, vitality, or performance. For accurate levels, a functional blood test is required.
Is this testosterone calculator accurate?
The core ADAM questionnaire is clinically validated with high sensitivity (88%) and specificity for certain symptoms (e.g., 75.5% for erectile function). It’s an effective screening tool for high performers, but results are indicative only—not a diagnosis.
What does a high risk score mean?
A higher score suggests suboptimal testosterone could be contributing to symptoms like crushing fatigue, low libido, brain fog, muscle loss, or reduced performance. If you experience 3 or more key symptoms, it may be worth investigating further with blood testing.
What are signs of low testosterone?
Common indicators include decreased libido, lack of energy, reduced strength/endurance, weaker erections, low mood, poor sports performance, and falling asleep after dinner. Lifestyle factors like poor sleep, excessive alcohol (>14 units/week), or inadequate resistance training can also increase risk.
How many morning erections are normal?
Healthy men typically experience 3–5 morning erections per week. Fewer than this can be an indicator of suboptimal testosterone.
This is only a screening tool—not medical advice or a diagnosis. Can I use it instead of seeing a doctor?
No. While helpful for awareness, it cannot replace professional medical evaluation or blood testing. Always consult a healthcare provider for symptoms or concerns.
What are normal testosterone levels for men?
“Normal” ranges vary by lab and age, but NHS pathological ranges are typically 8–29 nmol/L. For high performers, optimal functional ranges are often higher (e.g., 20–30 nmol/L total testosterone) to support peak energy, mood, and performance.
How can I improve my testosterone risk score naturally?
Focus on 7–9 hours of quality sleep, resistance training 2–4 days per week, limiting alcohol to <14 units/week, managing stress, and maintaining a healthy body composition. The tool provides personalized recommendations after completion.
