Dr. Jamie Lynn Jaqua, MD

Originally from Sioux Falls, South Dakota, Dr. Jaqua graduated magna cum laude from Arizona State University with a B.S. in Microbiology. She earned her medical degree from the Sanford School of Medicine at the University of South Dakota, completed her residency at UT Southwestern Austin at Dell Children's Medical Center, and finished a fellowship in Pediatric Emergency Medicine at Wake Forest School of Medicine.

After years in high-acuity emergency medicine, Dr. Jaqua recognized a gap in traditional healthcare — the absence of time, personalization, and proactive care. In April 2023, she founded Vitality Testosterone & Weight Loss to deliver a more focused standard of care built around clinical excellence, prevention, and long-term optimization.

Her practice is built around a data-driven, individualized care model. Every patient receives a treatment plan tailored to their physiology, goals, and lifestyle — not a template. She specializes in TRT for men and advanced medical weight loss and peptide therapies for men and women, with an emphasis on results that last. On the peptide side she is the prescribing physician for every protocol the clinic dispenses — what that involves in practice is set out on the peptide therapy page.

Two threads run from that training into how she practices now. Emergency medicine teaches you to work from objective data under time pressure and to be honest about uncertainty — you do not get to guess. Pediatrics teaches you that the person in front of you exists inside a family, a schedule and a set of constraints, and that a plan which ignores those is a plan that will not be followed. Both show up in a hormone and metabolic practice, where the temptation to treat a number rather than a patient is constant.

She holds certification as a Medical Weight Management Provider through the International Association for Physicians in Aesthetic Medicine, and has completed the American Academy of Family Physicians program on protocols for hormone replacement therapy, alongside further training in metabolic health and hormone optimization. That additional training is deliberate: hormone and metabolic medicine is a field where a great deal of what circulates online is commercial rather than clinical, and keeping current with the actual evidence is the only defense against drifting toward what sells.

Outside the clinic, Dr. Jaqua prioritizes her own health and fitness, and enjoys an active lifestyle with her two sons — including music, dance, watersports, and anything near the ocean.

“Physician-led” is a phrase almost every hormone clinic uses, and in a lot of them it describes a name on a license rather than a person you will ever meet. The model that has spread across the sector — an online intake form, an asynchronous review by a prescriber in another state, a shipment, and a subscription — is legal and it is convenient. It is also structurally incapable of noticing the things that matter most in this kind of medicine.

At Vitality it means something narrower and more literal: Dr. Jaqua sees you, reads your labs herself, and sets and adjusts your protocol. Your dose is not stepped up by a template on a schedule. If your hematocrit is climbing on TRT, or your weight loss has stalled at a dose that should be working, or your energy has not improved despite numbers that say it should have, that is a conversation with the physician who prescribed it — not a support ticket.

The practical consequence is that this practice is smaller and slower than a subscription platform, and it is not trying to be otherwise. There is a ceiling on how many patients one physician can know properly, and staying under it is the point.

It is usually more useful to know where a clinic draws its lines than to read another list of what it offers.

We do not treat without labs. If you want a prescription based on a symptom questionnaire, this is not the practice for it.

We do not offer testosterone pellets. Vitality treats with injectable testosterone cypionate only. Once a pellet is implanted the dose cannot be adjusted for months, and dose adjustment is central to how Dr. Jaqua manages TRT.

We do not prescribe for performance enhancement. TRT restores testosterone to physiological range to correct a documented deficiency. Supraphysiologic dosing for athletic or aesthetic purposes is a different activity and not one carried out here.

We do not describe compounded medications as FDA-approved. Compounded semaglutide is not a generic of Ozempic or Wegovy, and the peptides offered here are prescribed off-label without FDA approval for those uses. Those statements appear on the relevant treatment pages because patients are entitled to know what they are being prescribed.

We do not prescribe when the answer is somewhere else. Some patients arrive wanting hormone therapy and leave with a referral, because the labs point at a thyroid problem, a sleep disorder, or something that needs a specialist. Losing that consultation is a better outcome than treating the wrong thing.
