  • HSA and FSA documentation provided
  • King of Prussia, PA

How it works

Request, get cleared, test, then sit down with the results.

No checkout, on purpose: exercise testing needs a short screening first.

  1. Request a package

    Pick what you want measured. No payment online. We reach out within one business day.

  2. Screening and clearance

    A short health and injury-history screen. If a test needs clinical clearance first, we tell you.

  3. Test day

    King of Prussia, standardized protocols on every device. Baseline takes 75 to 90 minutes. You pay at your visit.

  4. Your report, read by a physician

    Dr. Christian reads your results against your history and goals; the larger packages add a sit-down to turn them into a plan.

About the longevity program

Physician-guided peptide therapy

Already using peptides, or thinking about it? Get a physician in the loop.

Most peptides sold online are not approved drugs, and many arrive with no verified purity or identity. Dr. Christian has written a five-part series on what the research actually shows. If you want a physician in the loop, he prescribes only through licensed pharmacies, with a target and a stopping rule. In King of Prussia, or by video across Pennsylvania.

  • Every common peptide explained in plain language, with no hype and no stacks
  • Licensed pharmacies only; never research-chemical sellers

Not sure where to start?

Pick the one that sounds like you.

A starting point. The right fit is confirmed on your screening call.

Single tests and visits

A lower-cost way in. Standardized protocol, clear report, no physician evaluation unless you add one.

InBody body composition

$75

Body composition and longitudinal trends

Lean mass, fat mass, and segmental balance. Results are estimates affected by hydration, so we standardize timing to keep them comparable visit to visit.

Jamar grip strength assessment

$65

Maximum and mean grip, both hands

Three trials per hand on a consistent posture and handle setting. A quick, repeatable marker of overall strength.

VALD lower-body strength & power

$195

20 to 30 minutesJump height, peak force, side-to-side differences

Countermovement jump and isometric testing on ForceDecks, three valid maximal trials after a standardized warm-up.

PNOĒ resting metabolic assessment

$250

25 to 35 minutesResting energy expenditure, fuel use

What your body burns at rest and the balance of fat and carbohydrate it runs on. The number every fueling plan should start from.

PNOĒ VO₂ max assessment

$395

45 to 60 minutesVO₂ peak, heart-rate response, thresholds when valid

An individualized graded exercise protocol with pretest screening. One of the strongest single measures of cardiorespiratory fitness.

Bundle

PNOĒ resting + VO₂ max

$575

Both metabolic tests in one visit

Resting metabolism and aerobic capacity together, so training zones and fueling are built from the same day's data.

Bundle

Functional Performance Profile

$295

VALD + grip + InBody

Strength, power, and body composition in one visit. A practical snapshot for athletes who already know their aerobic numbers.

Bundle

Complete Physiological Performance Profile

$695

VO₂ max + VALD + grip + InBody

Every device in one visit, as testing only: standardized measurements and a report, without the physician evaluation of Performance Baseline.

Physician performance consultation

$450

45 minutesWith Dr. Christian

Bring your training history, your results from here or elsewhere, and your goals. Leave with a physician's read and a plan for what to measure next.

Follow-up performance consultation

$250

30 minutesFor existing patients

Review progress, repeat numbers, and adjust the plan.

Laboratory testing, when ordered, is billed separately unless a package says it is included. Testing-only services provide standardized measurements and reports; a full diagnostic medical evaluation is a separate service.

Ongoing care

Two memberships, one idea: measure over time, and adjust.

Each starts after an initial evaluation, purchased separately. Labs and treatments are additional unless contracted.

$495per month

$5,940 a year. Initial hormone or metabolic evaluation purchased separately.

Read before you book

What performance testing is, and what it is not.

  • Clearance comes first. Clinical clearance and appropriate test selection are required before exercise testing. Your screening decides which tests are right for you.
  • Testing is not a diagnosis. Testing-only services provide standardized measurements and reports. A full diagnostic medical evaluation is a separate service.
  • Labs are ordered to the person. Laboratory testing is billed separately unless a package includes it, and not every athlete needs every panel.
  • Return-to-Performance is not clearance. It documents rehabilitation progress for you and your treating team; it is not a stand-alone return-to-play decision.
  • Asymmetry is a measurement, not a prediction. Side-to-side differences are reported as measured and are never presented as validated injury predictions.
  • Body composition is an estimate. InBody results are affected by hydration and are not a direct measurement of muscle tissue.
  • Tested athletes. Any hormone, peptide, infusion, or regenerative treatment gets sport-specific anti-doping review first. Performance testing never implies that experimental interventions are necessary or proven.
  • Nothing here is medical advice. Reading this page does not create a physician-patient relationship.

The questions we hear before a first test.

Do I have to be a competitive athlete?

No. Performance Baseline was written for active adults, recreational athletes, and anyone who wants to know their aerobic capacity, strength, and body composition. The sport-specific labs and Elite 360 are there when you need more.

Why can I not pay for a package online?

Because exercise testing needs a screening first. When you send a request, we reach out within one business day to confirm the right package, run a short health and injury-history screen, and schedule you. You pay at your visit.

Does insurance cover this?

Programs at Aether Medicine are cash-based. Some laboratory work may be covered by your insurance, and we provide documentation for HSA and FSA reimbursement where applicable.

What do I need to do before test day?

We send preparation instructions when you book. Results depend on consistency, so timing of meals, hydration, and your last hard workout matters, and the same conditions are repeated at every follow-up test.

When do I get results?

Your measurements are recorded on test day. The physician-reviewed report follows, and packages with a results consultation include time with Dr. Christian to go through it and decide what to change.

Can any of this be done by telehealth?

Testing happens in person at our King of Prussia clinic. Results and follow-up consultations can be done by video for patients in Pennsylvania.

I am tested for anti-doping. Is that a problem?

No. Tell us when you book. Testing itself does not involve any substance, and any treatment considered afterward gets a sport-specific anti-doping review before it is recommended.

Package, single test, or membership: how do I choose?

A single test answers one question. A package answers how your systems work together and includes a physician read. A membership is for after that, when you want the same numbers measured again on a schedule and the plan adjusted. If you are unsure, send a request and say so; the screening call is where we sort it out.

Do I need an evaluation before joining a membership?

Yes. Both memberships start after an initial assessment, which is purchased separately: a performance package for the Performance Continuum, a hormone or metabolic evaluation for the Hormone & Cardiometabolic Continuum. The membership is everything that comes after it.

How often should I retest?

For performance, the Continuum schedule is the practice's answer: VO₂ max and resting metabolism twice a year, force plates, InBody and grip quarterly. For hormone and metabolic treatment, labs are rechecked on the schedule your protocol calls for, and body composition changes typically show over 8 to 12 weeks of treatment.

Can hormone or metabolic care be done by video?

Yes, for patients in Pennsylvania, including the first visit. We send the lab order to a draw site near you, go through the results and the plan on screen, and handle follow-ups and dose adjustments the same way. Testing on the devices happens in King of Prussia.

Do you prescribe peptides?

Where the research and your evaluation support it, yes, through licensed pharmacies only. Dr. Christian has written a five-part series on what the research shows for each peptide. Many people who come in asking for a peptide need something else first, and some need none. Look up a peptide.

Can you share my results with my coach, trainer or doctor?

Yes, with your consent. Reports are written to be used by the people working with you, and the memberships include coordination with them.
