12 Red Flags of a Bad Stem Cell Clinic
You do not need a medical degree to assess a stem cell clinic. Most predatory operators share a recognisable set of behaviours, and none of them require clinical knowledge to spot.
Work through these twelve. Any single one warrants a hard question. Three or more, and we would walk away.
1. It claims FDA approval
Almost nothing in this space is FDA approved. If a clinic says its treatment is, it is either mistaken about its own product or misleading you. Both are disqualifying.
A good clinic instead: tells you plainly that the treatment is not FDA approved, and explains what that means.
2. It emphasises "FDA registered"
Facility registration is an administrative listing with no review of safety or effectiveness. Its prominence in marketing is a deliberate choice of words designed to sound like approval.
3. It treats an implausibly wide list of conditions
Arthritis, autism, COPD, diabetes, MS, erectile dysfunction and ageing from the same infusion. Real cell therapy is narrow and specific. A long list means one product being sold many ways.
A good clinic instead: treats a focused set of conditions and can explain the biological rationale for each.
4. It quotes success rates it cannot source
"Ninety percent of our patients improve." Ask where that figure comes from. If the answer is internal data with no control group, no published methodology, and no independent review, it is marketing, not evidence.
A good clinic instead: cites published randomised trials, and tells you where the evidence is weak.
5. It uses testimonials in place of data
Video testimonials are the most persuasive and least reliable evidence in medicine. They cannot distinguish treatment effect from placebo, natural fluctuation, or selection.
6. It creates urgency
Expiring discounts, "one slot left this month," pressure to decide before you leave. Medicine does not run flash sales. This is the single most reliable indicator that you are in a sales process rather than a clinical one.
7. It will not price the treatment before a consultation
Pricing gated behind a consultation exists so the number can be tuned to your apparent means.
A good clinic instead: gives itemised pricing in writing on request.
8. No named physician performs the procedure
You should know who is treating you, their specialty, their licence number and state, and be able to verify all of it independently through the state medical board.
9. It will not disclose cell type, source, dose or viability
This is the most technically revealing question you can ask. What cells, from where, how many, how is viability measured, and can you see the lot documentation? A serious provider has these numbers. Most do not.
10. It discourages a second opinion
Any clinic that responds badly to "I’d like to discuss this with my orthopaedic surgeon first" has told you what it is optimising for.
11. It charges you to join its "study"
Genuine clinical trials are registered on ClinicalTrials.gov, overseen by an institutional review board, and generally do not charge participants. A $20,000 "patient-funded study" is a sale wearing a lab coat.
12. It promises, guarantees, or says "no side effects"
No medical procedure is free of side effects, and no honest clinician guarantees a result. Both statements are also the exact language regulators cite in enforcement actions.
The one question that sorts most clinics
"Can you send me the peer-reviewed randomised controlled trial supporting this treatment for my specific condition?"
Send it by email so you have the reply in writing. A serious clinic sends a paper, sometimes with a caveat about how strong it is. A predatory one sends testimonials, a brochure, or a phone call to "discuss it properly." The response, not the treatment, is what you are testing.
What good looks like
Honest about the evidence, including its weaknesses. Narrow in what it treats. Transparent about price. Names its physicians. Discloses cell type and dose. Encourages second opinions. Explains what happens if a complication develops after you go home. Does not push.
