Reset. Optimize. Elevate.

I'm Nelli Berberyan, Board Certified Doctorate Nurse Practitioner, stem cell and peptide specialist, and the founder of VĪVA Institute.

My clinical foundation was built where the stakes are highest: UCLA Health's Ronald Reagan Medical Center, on the cardiothoracic surgical unit, caring for open heart surgery, heart and lung transplant, and critical cardiac patients. From there I spent years as a family practice provider. And for the past five years, IV vitamin therapy has been my hands on science: first at the bedside, then through IV101, the vitamin infusion practice I founded in 2022.

Through all of it, one frustration I couldn't shake: too many people are told their labs look fine while they feel anything but. Tired, foggy, inflamed, slower than they used to be, and quietly dismissed. Your body deserves a far closer look than a fifteen minute visit and a standard panel can give it. So I built the place that finally gives you one.

Everything here starts with measurement, and we go deep. More than 160 markers even on the minimum panel, read together, line by line. Finally, real answers. From there, I build your protocol personally. Targeted nutraceuticals. Advanced peptide therapy where appropriate. And a one on one with me, every single month. Nothing automated. Nothing generic. Me, at every step.

Nearly a decade in healthcare. Deep specialization in stem cell and peptide science. My standard is simple: measure first, personalize everything, and prove the change with data.
