Why This Matters

Training hard doesn't mean
training smart

If you're not recovering, struggling to shift fat, feeling drained or plateauing — your blood doesn't lie. The answers are already in your body.

⚡

Your hormones control everything

Testosterone, cortisol, thyroid. If any of these are off, no amount of training or nutrition will fix it. You need to know where you stand.

🔄

Recovery starts in your blood

Inflammation markers, iron, ferritin — these tell you exactly why you're not bouncing back. Guessing your recovery isn't a strategy.

🎯

Your nutrition is probably wrong

Magnesium, B12, vitamin D — deficiencies directly tank energy, sleep and muscle function. Without data, every supplement is an expensive guess.

📈

You train hard. But are you optimised?

Strength, stamina, hormones, recovery — if your biomarkers are off, progress slows. Training harder won't fix what your blood says.

What People Say

Real people, real results

★★★★★

"After a long-term illness I became totally the opposite of who I was — unhealthy, lethargic, low libido, spiralling into depression. Youth Revisited listened, took my bloods, and gave me life-changing advice tailored to my personal requirements. That was the first step to recovery and the new and improved me. I owe my new lease of life to Youth Revisited."

Mr. Raj Bharath

⭐ Most Popular

Performance

Competitive Athlete

Hormones, recovery, inflammation and iron — everything that drives athletic performance in one draw.

Full hormone profile (9 markers)

Testosterone (total & free), oestradiol, SHBG, LH, FSH, DHEA-S, prolactin and progesterone.

Cortisol

Chronic elevation is the hallmark of overtraining. Suppresses testosterone, blocks recovery and tanks sleep quality.

Thyroid (TSH, T3, T4)

A sluggish thyroid directly reduces training capacity, slows metabolism and worsens body composition outcomes.

Ferritin & iron studies

Low iron is the single most common cause of reduced athletic performance — and one of the most frequently missed.

CRP — inflammation

High-sensitivity CRP reveals chronic inflammation that silently blocks recovery, adaptation and hormone production.

Vitamin D & B12

Vitamin D drives muscle function and immune response. B12 is essential for red blood cell production — deficiency destroys endurance.

Full blood count (14 markers)

RBC, haemoglobin, haematocrit, WBC, platelets and more. The complete haematological picture every serious athlete needs.

Liver & kidney function

ALT, ALP, GGT, creatinine, urea — essential if you train hard, use supplements or are considering performance support.

Blood draw included

Professional venous blood draw by a qualified phlebotomist, on-site at your gym. Nothing extra to pay.

About this testCompetitive Athlete£175

Hormone Health

Male Hormone Advanced Test

Core male hormonal baseline — the markers that govern how you feel, recover and perform.

Testosterone (total & free)

Measures both overall and bioavailable testosterone — key for energy, libido, muscle mass and mood.

Cortisol

Your stress and recovery hormone. Chronically elevated cortisol suppresses testosterone, disrupts sleep and promotes fat storage.

Thyroid (TSH, T3, T4)

Controls metabolism, energy production and weight. Often missed as a root cause of fatigue, brain fog and unexplained weight gain.

Oestradiol (E2)

Essential in men for bone density, cardiovascular health and mood. Both too high and too low causes problems.

SHBG

Sex hormone binding globulin. Determines how much testosterone is actually free and available for your body to use.

Blood draw included

Professional venous blood draw by a qualified phlebotomist, on-site at your gym. Nothing extra to pay.

Prolactin

Elevated prolactin can suppress testosterone and LH, leading to low libido, fatigue and fertility issues — often overlooked in male hormonal panels.

FSH

Follicle-stimulating hormone. Signals the testes to produce sperm and supports reproductive health — a key marker for assessing fertility and pituitary function.

Luteinising hormone drives testosterone production in the testes. Low LH points to a pituitary or hypothalamic issue as the root cause of low testosterone.

DHEAS

A precursor hormone produced by the adrenal glands that converts into testosterone and oestrogen. Declines with age and is a reliable marker of adrenal reserve and vitality.

FAI

Free Androgen Index. A calculated ratio of total testosterone to SHBG — gives a clearer picture of how much active testosterone is available at a cellular level.

About this testMale Hormone Advanced Test£135

Hormone Health

Female Hormone Advanced

Comprehensive female hormonal profiling — cycle health, fertility markers and thyroid function in one draw.

Oestradiol (E2)

Primary oestrogen governing cycle regulation, bone density, mood and skin health throughout life.

Progesterone

Balances oestrogen, supports deep sleep quality and is critical during the luteal phase of the cycle.

LH / FSH

Pituitary hormones that drive ovulation and follicle development. Key markers for fertility assessment and cycle health.

Thyroid (TSH, T3, T4)

Thyroid dysfunction is behind many unexplained symptoms in women — fatigue, weight gain, mood changes, hair loss.

SHBG

Influences how hormones behave throughout the cycle and affects libido, energy and free testosterone levels.

Blood draw included

Professional venous blood draw by a qualified phlebotomist, on-site at your gym. Nothing extra to pay.

Longevity

Health Optimisation

Cardiovascular health, metabolic risk, nutrient status and hormonal balance — built for longevity and peak function.

Lipids & cardiovascular risk

Total, HDL, LDL and non-HDL cholesterol plus triglycerides — your full cardiac risk profile.

HbA1c & insulin

Long-term blood sugar control and insulin sensitivity — the two most predictive metabolic risk markers.

Hormone screen

Testosterone, oestradiol, SHBG and thyroid — hormonal balance underpins every aspect of how you feel and function.

Liver & kidney function

ALT, ALP, GGT, bilirubin, albumin, creatinine, urea, eGFR — a full organ health check.

Vitamins & minerals

Vitamin D, B12, folate, magnesium — the nutrients most commonly deficient in UK adults, often without symptoms.

Blood draw included

Professional venous blood draw by a qualified phlebotomist, on-site at your gym. Nothing extra to pay.

About this testHealth Optimisation£240

✦ New Biomarker

Advanced Hormones

Pregnenolone

The master precursor hormone — upstream of testosterone, cortisol, oestrogen and DHEA. Now available as a standalone panel.

Pregnenolone

Produced directly from cholesterol — the upstream source of nearly every steroid hormone in the body.

DHEA-S

Downstream of pregnenolone — a key anti-ageing and vitality marker that declines steadily from your early 30s.

Cortisol

Competes with DHEA in the pregnenolone cascade. Chronic stress literally steals raw material from your hormone production.

Progesterone

A direct pregnenolone metabolite — important for hormonal balance in both men and women, and often overlooked.

Blood draw included

Professional venous blood draw by a qualified phlebotomist, on-site at your gym. Nothing extra to pay.

About this testPregnenolone£175

The Full Picture

Athlete + Pregnenolone

Everything in Competitive Athlete, combined with full pregnenolone cascade mapping — the most complete performance picture we offer.

Everything in Competitive Athlete

Full hormones, haematology, cortisol, ferritin, iron, CRP inflammation, vitamins D & B12, liver and kidney function.

Pregnenolone

The master upstream hormone — shows where your entire steroid hormone system begins and how much raw material you have.

DHEA-S

Key performance and anti-ageing marker — drops with age and chronic stress, and often explains plateau in trained athletes.

Full steroid cascade

See exactly how your body converts pregnenolone through the entire hormonal hierarchy — where it flows and where it stalls.

Adrenal reserve markers

Reveals how much hormonal reserve your adrenal glands have — critical for high-output athletes and those under sustained stress.

Blood draw included

Professional venous blood draw by a qualified phlebotomist, on-site at your gym. Nothing extra to pay.

Genetics

DNA Analysis

Your genetic blueprint — analysed once, relevant forever. How your DNA shapes hormone metabolism, injury risk and training response.

How efficiently your body produces, converts and clears key hormones including testosterone and oestrogen — written in your DNA.

Injury & recovery risk

Collagen gene variants that determine tendon and ligament resilience under load. Train smarter based on your genetic risk.

Nutrient absorption profile

Which vitamins and minerals your genetics make you prone to absorbing poorly. Personalise your supplements with certainty.

Cardiovascular genetic markers

Inherited cardiac and lipid risk factors — understand your baseline long before any symptoms appear.

Power vs endurance profile

Your genetic training response — whether your body is wired for strength or aerobic performance. Train with the grain of your biology.

Sample collection included

Simple saliva swab — no needles. Taken at home and posted to the lab. Results in your dashboard within 4 weeks.
