Verified listingAbout Advanced Longevity
What is Advanced Longevity?
Advanced Longevity is a membership practice built around preventive testing and longevity medicine. Most of what it offers is testing: full body scans, brain MRI and MRA with AI analysis, ultrasounds, blood tests, DNA testing, metabolic testing and cardiac evaluation. Hormone therapy and peptide therapy are listed as its own services, alongside nutraceuticals and remote heart monitoring.
Hormone therapy covers men's, women's and couples' hormone optimization, bioidentical hormone replacement, testosterone replacement, estrogen and progesterone therapy, and thyroid hormone therapy. Peptide therapy is listed for anti-aging, immune system support, muscle growth and recovery, and cognitive enhancement. The clinic does not name the specific hormone or peptide medications it uses.
It has offices in Oklahoma City, Plano and Houston. Its listed prescribers are Dr. Donald "Dean" Yarbro, Jr., MD; Dr. Keith Lewis, MD; Dr. Ramy Mankarious, MD; Dr. Ryan Williamson, MD; and Natalie Greer, MSN, AGNP-C. The clinic does not say which of them prescribes hormone or peptide treatment. Steve Marler is named as founder. Its Google listing shows a rating of 5 from 26 reviews, under the category Medical Center.
What does it cost?
It does not publish prices for hormone therapy or peptide therapy, and it does not say whether insurance is accepted. Its main package is the Advanced Longevity Program. The clinic describes it as including a full body scan, a calcium score, brain MRI and MRA, cancer blood tests in Year 1 and Year 5, one year of DNA testing, metabolic and microbiome testing, peptide therapy and hormone therapy recommendations, remote heart monitoring, and an annual full membership to Direct Cardiac Care Clinics.
The clinic invites you to discover pricing plans, but it shows no amounts. It does not state a consultation fee, and it does not say whether medication is included in any plan. Getting in touch to learn about the program is free of charge.
What should you ask before you book?
Ask which prescriber will sign off on any hormone or peptide treatment, and whether you will see that person at each visit. Ask whether a membership fee covers medication, or whether drugs, lab work, imaging follow-up and visits are billed separately. If a medication is recommended, ask whether it is brand-name or compounded, and which pharmacy fills it. Ask what repeat lab work and ongoing monitoring cost, since the clinic describes monitoring throughout hormone and peptide treatment without listing a price. Ask whether any of the testing can be billed to insurance.
Ask how a membership is cancelled and whether there is a fee for leaving early. If you live outside Oklahoma City, Plano or Houston, ask which office serves you. The clinic does not say which location serves McAllen or the Rio Grande Valley. Hours are not listed, and it does not say whether follow-up visits can be done by video, so ask both.
Who is it a good fit for?
This is a good fit if you want imaging, cancer blood screening or DNA testing as a starting point and are comfortable paying a membership before you know the full cost of any treatment. It is a weaker fit if you want hormone or peptide treatment with a price you can see in advance, since neither is priced publicly.
