A Trusted Partner for Your Complex Hormone Cases
PHC works directly with clinicians and clinics whose patients need advanced hormone evaluation, functional medicine workup, or management of conditions that fall outside the scope of standard hormone replacement protocols. We make it easy to refer with confidence — and we keep you in the loop.
Submit a Referral or Inquiry How It WorksYour Difficult Patient Has Somewhere to Go
Most hormone clinics are built around testosterone, estrogen, and progesterone replacement — and they do that well. But clinical practice regularly surfaces patients whose needs go further: a thyroid presentation that isn't responding, a fatigue pattern that doesn't fit a clean hormone deficiency, a patient who's been optimized on paper but still feels terrible.
Those patients deserve more than a protocol adjustment. They need a physician with the time, training, and clinical framework to evaluate the full picture. That's what PHC provides.
Referring to PHC isn't losing a patient. It's giving them the next level of care — and having somewhere to send the cases that are keeping you up at night.
When to Consider a Referral
On Standard HRT But Still Symptomatic
Testosterone, estrogen, and progesterone are optimized. Labs look appropriate. The patient still doesn't feel well. This almost always points to thyroid dysfunction, adrenal dysregulation, or a functional medicine issue that wasn't part of the original workup.
Thyroid Involvement Suspected or Confirmed
Patients who need desiccated thyroid extract (DTE), compounded T3/T4 protocols, or a full thyroid antibody workup fall consistently outside standard hormone replacement scope. If thyroid is in the picture, PHC is the appropriate next step.
Adrenal Dysfunction Is in the Picture
Adrenal fatigue, subclinical insufficiency, and HPA axis dysregulation present with profound fatigue, poor stress tolerance, and orthostatic symptoms. These patients are frequently misattributed to hormone deficiency alone and don't respond to standard replacement.
PCOS or PMDD Is Part of the Presentation
Both conditions involve hormonal, metabolic, and inflammatory components that require evaluation beyond what standard hormone replacement addresses. PHC manages these as integrated clinical presentations, not isolated symptom clusters.
Chronic Fatigue, Fibromyalgia, or Dysautonomia
Multi-system conditions with overlapping hormonal, mitochondrial, and autonomic contributions. These patients need a functional medicine framework — not more hormone titration.
Gut Health or Systemic Inflammation
When a patient's symptom pattern suggests gut dysfunction or metabolic disruption alongside their hormone presentation, a functional medicine evaluation is warranted.
Advanced Peptide Therapy Is Indicated
Beyond foundational peptide protocols, PHC offers advanced peptide therapy for metabolic function, cognitive performance, mitochondrial support, and tissue recovery — requiring physician-level evaluation and monitoring.

PHC offers two referral models depending on how involved you want to remain in the patient's care.
PHC sees patients via telemedicine across Texas and Arizona. Referrals are straightforward — no complex intake forms or lengthy wait times. Patients are evaluated thoroughly, communicated with clearly, and returned to your care better supported.
We don't compete for your patients. We solve the problem that was making them difficult to manage — and send them back.
