Reddit discussion
Mixedacross 5 threads
R3 comes up often in r/stemcells and the discussion is heavily critical. Commenters repeatedly flag the founder's revoked Arizona medical license, an FDA warning letter, and doubts about frozen cell viability and value for money. A few posters reported joint pain relief after treatment, while others reported no change months later.

What Patients Say
Both reviews are five stars. One reviewer had a single injection into the shoulder and reports full recovery of range of motion alongside strength work afterwards. The other names Dr. Greene and Samantha, and describes a stem cell treatment plan explained in full and adapted to their case, with support at each stage.

Dr Greene and Samantha are absolutely fantastic! The staff was professional, knowledgeable, and truly cared about my well-being. The stem cell treatment was thoroughly explained and tailored to my needs. I felt supported every step of the way. Highly recommend this clinic for anyone exploring regenerative therapiesโit exceeded my expectations!
How to read these reviews
Every review here comes from someone who says they were treated at R3 Stem Cell in Scottsdale, Arizona. Our moderation team reads each one before it goes up. We check that it describes a real visit and stays inside our content rules. We do not check whether the treatment worked. R3 Stem Cell gets no say either way: the clinic cannot approve a review, edit one, or have one taken down. None of the reviews here are treatment-verified yet, so read them as first-hand accounts rather than confirmed records.
What patients are reviewing
R3 Stem Cell is a regenerative-medicine provider based in Scottsdale, Arizona, operating since 2012. The clinic offers Regenerative Orthopedics, Mesenchymal Stem Cell (MSC) Therapy, Allogeneic (donor) Therapy, Autologous (own-cell) Therapy and 5 more. Patients most often come to it for Knee Osteoarthritis, Joint Pain and Back & Spine. Published treatment costs run $3,999 to $18,499, though the figure a patient is quoted depends on what they are treated for and how many sessions they need. Staff are listed as speaking English and Spanish, worth knowing if you are flying in.
Keep that spread in mind while you read. A review of a knee osteoarthritis case tells you little about how the clinic handles the rest of what it offers, and a patient who lives nearby has a very different week from one who flew in for a single visit.
Before you book
Reviews are one input. Ask R3 Stem Cell for the rest directly: which cell source and preparation they would use for your condition, who performs the procedure, what the quoted price covers, what follow-up you get, and what evidence they are relying on. Vague answers to any of those are worth noticing.
The full R3 Stem Cell profile has the team, accreditations and treatment list. There is a separate page on what R3 Stem Cell costs, and you can read how we rank and verify clinics and how we moderate reviews. For anything clinical, ask a doctor who knows your history.
