▪ WHERE TO BEGIN ▪

Start with what matters most

Longevity care does not mean doing everything at once. Pick the change you want to feel first, and your provider builds your plan from there, adjusting it as your body and goals change.

01

Energy and focus

For afternoons that fade early and a mind that feels foggier than it used to.

Often starts with
NAD+
02

Sleep and recovery

For lighter sleep and workouts that take longer to bounce back from.

Often starts with
Sermorelin
03

Body composition

For lean muscle that is harder to hold onto and midsection changes that crept in.

Often starts with
Tesamorelin or Sermorelin
04

A healthy aging foundation

For staying ahead of the changes that come with age, before they slow you down.

Often starts with
NAD+
▪ Why longevity care ▪

Aging starts at the cellular level.

Many of the changes you feel with age, like lower energy, slower recovery and lighter sleep, trace back to shifts inside your cells. NAD+, a molecule your cells rely on for energy and repair, is one example: studies of human tissue have found its levels tend to fall as we get older. Longevity care targets these shifts directly, guided by a licensed provider.

▪ WHAT TO EXPECT ▪

Small shifts that build over time

Longevity care is a long game. Here is how a typical first year unfolds with Oak. Everyone responds differently, and your plan adapts with you.

Weeks 1 to 2

Getting started

Your provider reviews your assessment, your plan ships, and you settle into your routine. Some people notice early shifts in energy.

Month 1

Adapting

Your body begins responding. Check in with your care team, who can fine-tune your dose if needed.

Month 3

Feeling it

Some people report steadier energy, deeper sleep or quicker recovery, depending on their plan. Your provider reviews your progress.

Month 6

Building momentum

Consistency compounds. Your plan is refined around how you are responding and what you want next.

Year 1 and beyond

Staying ahead

Ongoing care keeps your plan matched to your body as it changes, so the progress you make holds.

Timelines are illustrative. Individual results vary and are not guaranteed.

▪ BIOLOGICAL AGE ▪

Your birthday says one thing. Your biology may say another.

Chronological age counts years. Biological age reflects how your cells and systems are actually aging, shaped by sleep, stress, activity and more. Longevity care focuses on the part you can influence.

+ QUESTIONS

Longevity, answered

What is longevity medicine?

Longevity medicine focuses on healthspan, the years you live in good health. Rather than cosmetic anti-aging fixes, it looks at the biological processes behind aging, such as energy production, cellular repair and hormone signaling, and supports them before problems build up.

What is the difference between healthspan and lifespan?

Lifespan is how long you live. Healthspan is how long you live in good health, free of the frailty and chronic conditions that limit daily life. The goal of longevity care is to extend both.

Which treatment should I start with?

It depends on the change you want to feel first. NAD+ is often a starting point for energy and focus, Sermorelin for sleep and recovery, and Tesamorelin for body composition. Your provider reviews your health history and recommends where to begin.

Can I combine more than one treatment?

Sometimes. Each option works on a different pathway, so some people layer treatments over time. Your provider decides whether combining is appropriate and sequences it safely rather than starting everything at once.

Are these treatments safe and FDA approved?

A licensed provider reviews your health history before prescribing anything. Compounded medications are not FDA approved and have not been reviewed by the FDA for safety or effectiveness. Possible side effects include injection-site reactions, flushing, headache and nausea, and your care team is available if you have questions.

How much does it cost?

NAD+ is $175 a month, regularly $199. Sermorelin and Tesamorelin pricing is shown after your free assessment. Every plan includes your provider review, ongoing messaging support and free discreet shipping. No insurance required.
