Clinic directory
Ranked by ARK Score — computed from five published factors, shown on every card. Prices are the clinic's own verified published prices. You arrange and pay treatment with the clinic directly; ARK does not sell treatment and takes no share of what a clinic charges you.
Computed in code from five published factors. No sponsorship, placement fee or partner status enters this function. The factor breakdown is shown on every card so a member can check the arithmetic.
- priceTransparency (25) — verified published price = 25 · inferred/aggregator price = 12 · not published = 0
- medicalLeadership (25) — named MD verified = 25 · physician-led inferred = 15 · unknown = 5 · not physician-led = 0
- regulatoryStanding (20) — regulator/accreditation verified = 20 · inferred = 12 · unknown = 5
- serviceEvidence (20) — library evidence grade of the clinic's primary service: A=20 B=16 C=12 D=8 E=5 F=2. Carried from the protocol cards, never re-graded here.
- disclosure (10) — 10 minus 3 per documented red flag, floor 0
- v0 has no outcome data, no patient-reported outcomes and no complication rates — because none of these clinics publish them. Absence is scored as absence, never as good.
- A high score means a clinic is transparent and credibly staffed. It does not mean the treatment works. Service evidence is capped at 20 of 100 precisely so that a clinic cannot score well on the strength of an unproven therapy.

- Off-label use; not covered by insurance.
- Cognition claims rest on Sagol trials that critics call small and contested — and HBOT for cognition failed a 2025 sham-controlled RCT, which is why ARK delists it for cognitive goals.
- Extreme cost per session relative to every other HBOT provider in this directory.
Medical leadership: Protocol developed with Dr Shai Efrati, Director of the Sagol Center, Israel. US clinic is physician-staffed.
Regulatory: US clinic operating under Florida medical practice regulation.

- Publishes biological-age claims ('2.61 years younger') that outrun the evidence — no human study has shown that lowering a clock reading extends life or prevents disease.
- TPE's own best-designed trial (AMBAR) missed one of two co-primary endpoints.
- Per-session price tier with a biomarker-only result behind it.
Medical leadership: Physician-run protocols across partner sites; per-site oversight varies and no single named medical director was captured.
Regulatory: US clinics; apheresis performed on FDA-cleared devices, off-label for this indication.
Shortlisted as a partner candidate: its entire model is layering onto existing clinics, which is the same shape as ARK's delivery-not-molecules position. The bio-age marketing would need to be firewalled from any ARK surface.

- Vietnamese-language public medicine — not set up for foreign wellness clients.
- Admission is indication-driven (stroke, wounds, burns), not protocol-driven.
- Equipment vintage unverified.
- Chamber pressure (ATA) is not published. The ~$12 session price is verified; the treatment PRESSURE is not. A 1.3 ATA session and a 2.0 ATA session are not the same product, and the ATA-dependent findings in the library — including the Thom 2006 CD34+ mobilisation result — were measured at 2.0 ATA. Ask for the protocol pressure in writing before treating this price as comparable to anything.
- The widely repeated '$55/session Vietnam' figure does not match any named facility. Verified public-hospital rates are $9–$20; $40–$60 is the plausible private/international landing zone but no facility publishing $55 was found.
Medical leadership: Government scientific centre with medical staffing; named medical director not captured in this research pass.
Regulatory: Vietnamese state scientific institution.

- Publishes attack-comparison content against competitors — marketing-forward posture.
- Physician licensure and lab certification are site-claimed, not independently verified.
- Systemic MSC infusion is not lawfully sellable in the US and carries a library grade of D.
Medical leadership: Licensed Mexican physicians with a COFEPRIS-licensed lab partner — site-claimed, not independently verified.
Regulatory: COFEPRIS-licensed lab partner claimed by the clinic; not independently confirmed.
Shortlisted as a partner candidate: per-cell pricing published, dual locations, package logistics built for US patients — the cleanest diligence profile in a category with poor hygiene overall.

Medical hard-chamber HBOT sold in packages, with adjuncts (IV therapy, PEMF, red light).

Medical leadership: Physician-supervised clinic; medical staff listed on site but the named medical director was not captured in this research pass.
Regulatory: US clinic under North Carolina medical practice regulation.
Shortlisted as a partner candidate in the seed research: independent, published package pricing, small enough to sign a referral arrangement, credible enough not to embarrass.

- SERIOUS: a 2019 autism paper was RETRACTED for failing to disclose pay-to-participate conflicts ($7,200 for four visits).
- That trial had no control group.
- Highest price in the regenerative set with no corresponding evidence advantage.
- Founder is not a physician.
Medical leadership: Founder and Chief Science Officer Neil Riordan is a PA and PhD, not an MD. Local physician staff deliver treatment.
Regulatory: Operates under Panamanian regulation; specifics not independently confirmed in this pass.
Included deliberately. It is the most famous clinic in the category and members will find it with or without ARK — so ARK publishes the retraction alongside the price.

Directory integrity
Listing is not endorsement. Red flags are published on the card, including for the highest-scoring entries.
Prices are the clinic's own verified published prices, re-checked on a published cadence. ARK does not set, discount, or sell a treatment price — the member arranges and pays the clinic directly (Catalog & Monetization Policy, 8/27).
Every price carries its verification label from the seed file: 'verified' means it was found on a published page or reputable secondary source with a URL; 'inferred' means an aggregator or competitor stated it, or it was estimated from range data.
Educational options, not medical advice. Nothing here is a diagnosis, a prescription, or a prediction of your individual result. Discuss any option with a licensed clinician who knows your history.
