About California Longevity & Vitality Medical Institute

What is MD Longevity?

MD Longevity is a physician-led age management and hormone therapy practice at 1112 Park Ave in New York. Ann J. Peters, MD, prescribes for patients there. The practice treats itself as a hub for hormone balance, body composition, and metabolic health rather than a single-issue weight loss shop, and its offerings reflect that: bioidentical hormone replacement therapy for men and women, age management and anti-aging medicine, nutrition and fitness guidance, stress reduction, and a GLP-1 weight loss program.

The weight loss program centers on semaglutide, which can be prescribed on its own or alongside BPC-157 or vitamin B12. It describes its program as including monthly prescriptions of the GLP-1 medication along with thyroid and metabolic testing every four months. The practice keeps regular business hours, Monday through Friday, 9 to 5. It does not say whether visits can be done by telehealth, so if you are not local to New York, that is worth asking about directly.

What does it cost?

No prices are published for the GLP-1 program, hormone therapy, or an initial consultation. It does not say whether the monthly fee, if there is one, includes the cost of the medication itself, and it does not state whether insurance is accepted in any form. Anyone considering this practice should ask for a full breakdown in writing before committing.

What should you ask before you book?

Ask whether Ann J. Peters, MD, is the prescriber who will actually review your case and sign your prescription, since that is the only prescriber named. Ask what the all-in monthly cost looks like, and whether that figure includes the semaglutide itself or whether the medication is billed separately. Ask whether the semaglutide used is brand-name or compounded, since the practice does not specify which. Ask what the thyroid and metabolic testing every four months costs, and whether that is bundled into the program fee or charged on top. Ask whether follow-up visits can be done remotely or require an in-person visit to the Park Ave office, since telehealth is not addressed. Finally, ask what the cancellation process looks like if you decide the program is not for you.

In its own words: "The program includes monthly prescriptions of GLP-1 and thyroid and metabolic testing every 4 months."

Who is it a good fit for?

This is a good fit for someone in or near New York City who wants a physician-run practice that treats weight management as connected to hormone and metabolic health, rather than a standalone prescription drop. It is less of a fit for someone who wants clear pricing up front or confirmed telehealth access before they pick up the phone, since neither is spelled out and both are worth settling in a first call.
