Which Test Is Right For You?
Answer a few quick questions to get a personalized panel recommendation.
Half of UK men with testosterone deficiency symptoms don't have a diagnosis—and 55% don't even recognise the symptoms. The right panel helps you understand what's really going on.
Get The Most Accurate Results
A few simple steps can significantly improve the accuracy and usefulness of your blood test results.
Test Before 10am
Testosterone peaks in the early morning and can drop 20-30% by afternoon. Morning testing gives you the most consistent baseline.
Fast Overnight

⚠️ EDUCATIONAL PURPOSES ONLY ⚠️
This information is provided for harm reduction and education. Aeternox does not recommend, promote, or encourage the use of performance-enhancing drugs. All use carries serious health risks.
The Reality: Health Statistics From PED Use
Why Monitoring Matters
While Aeternox does NOT encourage PED use, we recognize that individuals will make their own choices regardless of external advice. Our role is to provide the clinical monitoring that can:
- Detect dangerous biomarker changes before they become medical emergencies
- Enable informed decision-making about continuing, adjusting, or stopping use
- Provide the data needed to minimize harm in those who choose to use
- Reduce strain on NHS by preventing emergency interventions
Aeternox Enhanced
Advanced monitoring for enhanced individuals. Harm reduction, education, and complete biomarker analysis without judgement.
Harm Reduction, Prevention, and Education
We facilitate access to non-judgemental, laboratory-analysed monitoring for individuals who choose to enhance.
Aeternox Enhanced is a dedicated testing access service built for individuals who use performance-enhancing compounds and require specialised biomarkers, advanced monitoring, and deeper analysis than standard healthcare services provide.
Our mission is harm-reduction, prevention, and education.
Unique Risks of Enhancement
Without proper monitoring, these risks can go undetected until serious damage occurs.
Hormonal Imbalance
Disruption to natural hormone production and regulation
Liver & Kidney Strain
Organ stress from processing compounds
Lipid Disruption
Adverse changes to cholesterol balance
Cardiovascular Risk
Increased strain on heart and blood vessels
Prostate Stress
Elevated PSA and prostate concerns
Blood Thickening
Elevated haematocrit and clot risk
Thyroid Suppression
Disruption to metabolic regulation
Adrenal Disruption
Impaired stress response and cortisol regulation
Infection Risk
Injection site complications and bacterial concerns
Key Biomarkers Explained
Knowledge is power. Here's what these commonly monitored markers actually measure.
ALT & AST
Liver EnzymesEnzymes released when liver cells are stressed or damaged. Elevated levels may indicate the liver is working harder than normal. Many factors can influence these readings.
Haematocrit (HCT)
Blood ThicknessMeasures the percentage of red blood cells in your blood. Higher percentages mean thicker blood, which may affect cardiovascular function. Important for anyone training intensely.
LDL & HDL Cholesterol
Lipid BalanceThe ratio between these cholesterol types matters for cardiovascular health. LDL transports cholesterol to cells, HDL helps remove excess. Balance is key.
FSH & LH
Pituitary HormonesThese hormones signal your body to produce testosterone. Low levels may indicate the pituitary gland isn't signalling normally. Essential for understanding hormonal health.
eGFR
Kidney FunctionEstimates how well your kidneys filter waste. Important for anyone taking supplements or compounds that are processed through the kidneys. Higher numbers generally indicate better filtration.
PSA
Prostate MarkerProstate-Specific Antigen levels can be influenced by many factors. Tracking changes over time is more informative than single readings. Always discuss results with a healthcare professional.
For educational purposes only. Results should always be discussed with a qualified healthcare professional who can interpret them in the context of your individual health history.
Enhanced users face a unique set of risks—ranging from liver toxicity and kidney strain to lipid disruption, cardiovascular stress, and suppressed endogenous hormone production. Yet many struggle to access the testing they need due to stigma, judgement, or lack of understanding from traditional healthcare providers.
The NHS doesn't ask about enhancement, and users fear discrimination. GPs are often unable—or unwilling—to order the specific panels required. Private clinics may offer testing, but without the depth of biomarkers needed for true harm reduction.
Aeternox Enhanced bridges this gap. We facilitate access to comprehensive monitoring through our UKAS-accredited laboratory partner, without stigma, judgement, or barriers. Our Enhanced and Ultimate panels are specifically designed around the markers that matter most for detection, prevention, and safety.
Our Mission:
"To provide harm-reduction, prevention, and education for individuals who enhance—offering the monitoring, data, and privacy they deserve, without judgement or stigma."
How Enhanced Testing Supports The NHS
Private monitoring reduces strain on public healthcare by catching issues early and preventing emergency interventions.
Early Detection
Catching elevated liver enzymes, kidney markers, or lipid disruption before they become emergencies.
Fewer GP Visits
Direct access to testing without requiring GP appointments, referrals, or waiting lists.
Reduced Emergency Cases
Proactive monitoring prevents acute liver failure, kidney damage, cardiovascular events, and strokes.
Non-Judgemental Monitoring
Users access testing without fear of stigma, ensuring they actually seek help when needed.
Better Self-Management
Clear data empowers users to make informed decisions about cycling, dosing, and when to stop.
Prevention Culture
Shifting from reactive treatment to proactive prevention reduces long-term healthcare burden.
Education That Lowers Harm
Informed users make safer choices, reducing overall risk and preventing avoidable health complications.
The Bigger Picture: Prevention Over Treatment
Preventing Hospital Admissions
Regular monitoring catches liver enzyme elevation, kidney dysfunction, and haematocrit spikes before they become acute medical emergencies requiring A&E intervention.
Reducing Long-Term NHS Burden
Early detection prevents chronic conditions like cardiovascular disease, liver cirrhosis, and kidney failure that require decades of NHS treatment and management.
Enabling Informed Decision-Making
When users have clear data, they can make evidence-based decisions about continuing, adjusting, or stopping use—reducing harm and preventing irreversible damage.
Important: Non-Promotion Statement
Aeternox does NOT promote or encourage the use of performance-enhancing drugs.
Our role is harm reduction, education, and the safe monitoring of individuals who choose to enhance regardless of external advice.
We focus on:
- Safety
- Privacy
- Prevention
- Data clarity

How Often Should You Test?
If actively monitoring or using supplements/compounds
For general health maintenance and tracking trends
Minimum recommendation for all men over 30
Understanding Reference Ranges
How to interpret your results once they arrive.
Within Range
Results within the reference range are typically considered normal. However, where you fall within that range matters—low-normal versus high-normal can have different implications.
Optimal vs. Normal
Reference ranges are population averages. What's "normal" may not be optimal for you. Many men feel their best at the higher end of the testosterone range, for example.
Track Trends
Single snapshots are useful, but trends over time are more valuable. A dropping value—even if still in range—might be worth investigating with regular testing.
Always discuss results with a healthcare professional. Blood tests provide data, not diagnoses. A qualified professional can interpret results in the context of your full health picture.
