For hormone and metabolic patients
Answers first. Then a treatment built for you.
The full hormone panel, read by a physician, and a protocol written for one person.
Testosterone, estrogen, progesterone, thyroid with the free hormones, cortisol and DHEA, tested together and read against your symptoms. Bioidentical hormone replacement, thyroid support or peptides when the results call for it, designed and monitored by Dr. Christian himself.

Is this you?
Symptoms people live with for years before anyone measures them.
Each of these has a short list of measurable causes. A full panel, read by a physician, is how you find out which one is yours, or that none of them is.
Exhausted on a full night of sleep.
Seven hours in bed, and by mid-afternoon there is nothing left.
Weight and strength going the wrong way.
You train and eat the way you always have. The scale climbs and the lifts drop anyway.
Hot flashes, night sweats, broken sleep, a cycle that has changed.
You have been told it is a phase and offered patience. You would rather know what is happening.
Drive, recovery and libido not what they were.
Nobody has looked at the whole picture, so nobody has explained it.
Irritable or flat, for no reason you can name.
The people around you have noticed. You want a cause, not a guess.
If more than one of these is you, the next step is a panel, not another year of waiting.

What we test
One number is not a hormone evaluation.
A standard check runs a total testosterone or a TSH, compares it with a population range, and stops. These are the measures a real evaluation includes, and what each one explains about how you feel.
| System | A standard check | What we measure | What it explains |
|---|---|---|---|
| Testosterone | Total testosterone, if anything | Total and free testosterone, SHBG, estradiol, LH and FSH | Whether the hormone is there, whether it is available to your tissues, and whether the signal to make it is intact |
| Estrogen and progesterone | Rarely, unless you ask | Estradiol, progesterone and FSH, read against your cycle history or menopausal stage | Hot flashes, night sweats, sleep, mood, and why they arrive when they do |
| Thyroid | TSH alone | TSH, free T3 and free T4 | Energy, weight, cold intolerance and hair changes while TSH still sits in range |
| Cortisol and DHEA | Not measured | Cortisol rhythm and DHEA | The stress axis behind broken sleep, afternoon crashes and stubborn abdominal fat |
| Metabolic and inflammatory | Fasting glucose | Fasting insulin, HbA1c, lipids, inflammation markers and body composition | Hormones and metabolism move together; treating one without the other rarely holds |
Every panel read by the physician, not a portal
A real conversation before anything is ordered
A protocol for one person, adjusted as you respond
What to expect
How treatment runs
- 1 of 4
A real conversation first
Sleep, energy, weight, mood, libido, hot flashes, and what has changed. Your symptoms decide which tests are worth running; nothing is ordered on a template.
- 2 of 4
The full panel
Testosterone, estrogen, progesterone, thyroid, cortisol, DHEA, insulin and inflammation, drawn at the practice or by a lab order sent to a draw site near you.
- 3 of 4
A protocol written for you
Bioidentical hormone replacement, thyroid support or peptides where the results warrant them, alongside sleep, nutrition and stress physiology, with the risks explained before anything starts.
- 4 of 4
Re-tested and adjusted
Labs rechecked as treatment settles, doses adjusted, and the plan reviewed regularly. Some patients move to maintenance; some do not stay on hormones at all.

Questions we hear
Straight answers, before the first visit.
Yes. Hormone consultations can be done by video, including the first one. We send your lab order to a draw site near you, then go through the results and the plan together on screen. Follow-ups and dose adjustments work the same way. Dr. Christian is licensed in Pennsylvania, so telehealth is available to patients who are in Pennsylvania at the time of the visit.
Hormone optimization programs at Aether Medicine are typically cash-based. Some lab work may be covered, and we provide documentation for HSA and FSA reimbursement where applicable. Costs are explained before anything is committed, at the first visit.
Many patients notice early changes in energy and sleep within two to four weeks. Changes in body composition and brain fog typically take eight to twelve weeks, with lab rechecks along the way. Nobody is promised a result; the labs and the follow-ups are how we know whether the plan is working.
Not necessarily. Goals, protocols and duration are individual. Some patients transition to maintenance, others cycle on and off, and some are better served by thyroid or metabolic treatment than by hormone replacement at all. The risks, including fertility effects with testosterone, are part of the first conversation, and the plan is reviewed regularly.
Telehealth Available
You do not have to live near Philadelphia to be our patient.
Hormone and metabolic care is mostly conversation, laboratory work and adjustment over time. All three travel well. Patients across Pennsylvania do this with us on video, with their blood drawn close to home.
