The Practice

A physician-led practice for the protocols people actually come asking about.

Not a med-spa. Not a wellness influencer with a referral code. Real internal medicine for hormones, GLP-1s, peptides, and testosterone — supervised, lab-driven, and titrated to you.

Most patients arrive with a clear question and want a clear answer.

We start with a long conversation and a full panel. From there, every protocol is calibrated to your physiology — and adjusted again based on how you feel between visits.

That's it. No upsells, no proprietary blends, no template plans.

Services

Five focused protocols.

Every program begins with a full panel and a long conversation. Plans are built to your physiology — never copy-pasted.

01

Bioidentical Hormone Therapy

Hormone levels shift with age. The goal is simple: restore them to a healthy, balanced range — guided by your labs and followed over time.

ProtocolsEstradiol · Progesterone · DHEA · Thyroid
02

Testosterone Optimization

Fatigue, low drive, slow recovery, brain fog — worth confirming before treating. We diagnose with full labs, treat only when the bloodwork warrants it, and monitor closely.

ProtocolsTestosterone Cypionate · HCG · Anastrozole
03
Now Available

Medical Weight Loss — GLP-1s

A powerful tool — and it works best inside a supervised program that protects muscle, supports nutrition, and adjusts as your body responds. Results vary; the plan is built for the long term.

MedicationsOzempic · Wegovy · Mounjaro · Zepbound
04

Peptide Therapy

An evolving field, approached conservatively. In consultation, Dr. Sun reviews what the current evidence supports and whether it has a place in your plan.

By consultationReviewed individually — never off a menu
05

Personalized Wellness Plans

One coherent plan connecting hormones, metabolism, nutrition, sleep, and long-term health — with the time and continuity to actually follow it through.

The Physician
Board-Certified · Internal Medicine · Practicing since 2005

Dr. Lydia Sun MD, PhD · Internal Medicine

Trained as both a physician and a researcher — which means she reads the evidence critically before recommending it to you. She keeps the practice small on purpose, so every visit is unhurried and every plan is genuinely yours.

"I'd rather understand the whole picture before changing anything."

  • MD and PhD — a clinician's judgment paired with a researcher's read on the evidence.
  • Two decades focused on hormones, metabolism, and longevity medicine.
  • New Jersey practice — personalized, lab-driven, never templated.
  • Takes a limited number of new patients to keep care unhurried.
The Data

Measured, not promised.

No headline numbers and no guarantees — every plan is calibrated to your own labs and adjusted visit by visit. Most people notice energy and sleep first; the point is a plan that keeps fitting you as you change.
