HUM2N.

What HUM2N actually is

A functional-medicine practice that speaks the longevity dialect fluently — and then, unusually for London, has the regulatory standing to actually prescribe the protocols it diagnoses. Hormone replacement, off-label medications, compounded therapies: HUM2N’s clinicians do them, calmly, where most competitors hand you a list and a cab.

That capability is the substantive reason to consider them. Not the postcode. The flagship sits at 35 Ixworth Place in Chelsea; a second clinic opened in 2026 inside Six Senses London at The Whiteley, Bayswater.

The day

The Longevity Baseline Assessment (£1,495, or £1,695 with a nutritionist) buys blood, urine and gut testing across 150+ biomarkers, body composition and a one-hour physician consultation; VO₂ max testing is sold separately. The Essential Physiological Profile at £745 is the cheaper entry. Hormone-panel work is more comprehensive than the European median — urine and gut testing run alongside blood, which most clinics don’t bother to do.

What’s missing is significant: no whole-body MRI in the offer. Imaging has to be arranged elsewhere, at additional expense. If imaging is what brought you to longevity medicine, HUM2N is not the right starting point.

The hormone conversation

This is where HUM2N earns its keep. London is a difficult city to find a clinician comfortable with bioidentical HRT or off-label TRT. HUM2N’s clinicians run them, with documented protocols and structured follow-up.

Whether you should want these protocols is a separate question — and one the clinic, to its credit, will sometimes answer in the negative. We watched a forty-two-year-old in good metabolic health be talked out of a TRT trial. That’s a competent clinic.

Membership versus day-rate

The 12-month programmes are the sensible structure. Foundations costs £495 a month plus a £995 one-off fee (or £6,241 upfront) and repeats testing at six months; Longevity Optimisation costs £695 a month plus £1,495 (or £8,852 upfront). For anyone planning a six-to-twelve-month protocol, this beats paying test by test.

For a one-shot survey-the-system visit, however, you get more breadth elsewhere — see YEARS for that profile.

The verdict

HUM2N is the right clinic if you have a specific question — should I be on testosterone, can my mid-forties fatigue be diagnosed, what protocol survives twelve months — and want it answered, dispensed and reviewed under one roof. It is the wrong clinic if you want the full diagnostic spread, particularly imaging.

The clinic that prescribes is a different proposition to the clinic that recommends. Both are useful. Buy the right one.

Does HUM2N earn from the treatments it recommends?

Yes. We score this as a structural conflict of interest. Hormone optimisation, NAD+ and IV infusions, hyperbaric oxygen and ozone therapy are administered in-house — the same clinic that ran the diagnostics bills for the treatments, programme credits and supplements that follow. HUM2N scores 18/25 on conflict freedom.

— 03

Is HUM2N physician-led?

Yes. Medical leadership: Dr. Mohammed Enayat (Founder & CEO). HUM2N scores 21/25 on medical supervision.

How does HUM2N rank among longevity clinics?

HUM2N ranks #13 of 19 in the 2026 Longevity Clinics ranking, with 75/100 (Good, with caveats). Worth it for the patient with a specific question — less so for the survey-the-system reader.
