Test ID: S-123
The Essential Male Hormone Saliva Profile is an advanced at-home hormone test designed specifically for men, accurately measuring three core sex hormones Oestrogen— Estradiol (E2), Progesterone (Pg), and Testosterone (T) — using gold-standard LCMS (Liquid Chromatography–Mass Spectrometry) laboratory technology.
In men, these three hormones must be in precise balance. Testosterone drives energy, muscle, libido, and cognitive sharpness — but without adequate progesterone to regulate it and controlled oestradiol levels to complement it, even men with "normal" testosterone can experience significant symptoms. This test gives you an accurate, evidence-based picture of your hormonal status, interpreted by a specialist doctor.
Test from home with confidence — no clinic visit required.
Why Choose LCMS Hormone Testing?
Unlike standard immunoassay methods, LCMS (Liquid Chromatography–Mass Spectrometry) offers higher sensitivity and specificity, accurate measurement of active (bioavailable) hormones in saliva — reflecting the hormones actually reaching your tissues — reliable results for complex hormonal patterns including those seen during andropause or TRT, and greater precision for monitoring testosterone therapy. LCMS is considered the gold standard for advanced hormone analysis.
What This Test Measures
Testosterone (T)
The primary male sex hormone and the most critical marker in this panel. Testosterone drives libido and sexual function, muscle mass and physical strength, energy and motivation, mood stability and confidence, cognitive clarity and focus, and bone density. Testosterone declines gradually from around age 30 — a process known as andropause or late-onset hypogonadism — and can fall more sharply due to chronic stress, poor sleep, obesity, alcohol, or underlying health conditions. Saliva testosterone reflects free, bioavailable testosterone — the fraction that actually acts on your cells — making it a more clinically meaningful measure than total serum testosterone alone.
Estradiol (E2)
Oestradiol is present in men in small but physiologically important amounts. It supports bone density, cardiovascular health, brain function, and joint integrity. However, when oestradiol becomes elevated — which occurs when excess testosterone is converted to oestrogen via aromatase, particularly in men with higher body fat — it can cause symptoms including gynaecomastia (breast tissue development), water retention, low libido, erectile dysfunction, fatigue, and mood disruption. Elevated oestradiol also suppresses natural testosterone production. Monitoring the testosterone-to-oestradiol ratio is essential for men on TRT or those with suspected oestrogen excess.
Progesterone (Pg)
Often overlooked in men, progesterone is a key regulator of testosterone and oestrogen balance. It acts as a natural aromatase inhibitor — helping to prevent excess conversion of testosterone to oestradiol — supports sleep quality and mood, promotes prostate health, and protects against the effects of oestrogen dominance. Low progesterone in men is linked to anxiety, poor sleep, elevated oestradiol, and reduced testosterone effectiveness.
Who Should Consider This Test?
This saliva hormone profile is particularly relevant for men who experience:
- Low libido or reduced sexual interest
- Erectile dysfunction or reduced sexual performance
- Persistent fatigue or low energy despite adequate sleep
- Loss of muscle mass or difficulty building strength
- Increased body fat, especially around the abdomen or chest
- Brain fog, poor concentration, or reduced motivation
- Low mood, irritability, anxiety, or depression
- Poor sleep quality or difficulty staying asleep
- Symptoms of andropause (male menopause) — typically from age 40+
- Gynaecomastia or breast tenderness (possible sign of elevated oestradiol)
- Wanting to monitor testosterone replacement therapy (TRT)
- Feeling "off" hormonally but told results are "normal" on standard blood tests

Frequently Asked Questions
What hormones are included?
Testosterone (T), Estradiol (E2), and Progesterone (Pg).
When should I collect my sample?
Collect your saliva sample in the morning, ideally between 7–9am, when testosterone levels are naturally at their highest. Full guidance is included in the kit.
Can I use this test if I am on TRT?
Yes. This test is suitable for men on testosterone replacement therapy and provides valuable insight into how your hormones are responding to treatment, including oestradiol conversion.
How long until I receive results?
Results are delivered within 3–5 working days after laboratory receipt.
Is professional interpretation included?
Yes. Each report includes specialist commentary from a Hormone Specialist PhD Doctor.
How long is the kit valid?
12 months from purchase.
Who pays for shipping?
You are responsible for posting your samples to the laboratory.
