When the Problem Is More Than a Hormone Level
Advanced hormone and functional medicine consulting for clinicians managing complex cases — and for patients who haven't found answers through conventional care.
Two Ways to Work With PHC
PHC serves two distinct audiences — clinicians who need a trusted referral partner for complex cases, and patients who haven't found answers through conventional care.
A Trusted Referral Partner for Complex Cases
When a patient's needs exceed standard hormone replacement — thyroid dysfunction, adrenal dysregulation, PCOS, PMDD, chronic fatigue, dysautonomia, fibromyalgia, or a presentation that simply isn't responding — PHC is where you refer with confidence. Dr. Wilcox is available for direct patient referral or co-management consultation. Patients return to you better supported.

If you've worked with a primary care physician, an OB/GYN, or a hormone clinic and still don't feel well — or if your symptoms were dismissed because your labs came back "normal" — PHC provides the kind of thorough, root-cause evaluation that most clinical settings aren't structured to offer. We see patients whose complexity goes beyond standard hormone replacement.
Request a patient consultation →What Falls Outside Standard Hormone Replacement
Most hormone clinics will prescribe testosterone for men and women. Some will add estrogen and progesterone for women. Rarely do standard clinics venture beyond that — and even when they do, a meaningful subset of patients simply don't respond and need a more advanced approach. Beyond those three hormones, most clinics never go. That's the work PHC was built for.
Thyroid Optimization
Full thyroid evaluation including Free T3, Free T4, reverse T3, and antibody assessment. DTE and compounded T3/T4 protocols for patients who don't respond to standard levothyroxine.
Adrenal & HPA Axis Dysfunction
Adrenal fatigue, subclinical insufficiency, and HPA axis dysregulation — frequently missed on standard panels and misattributed to hormone deficiency alone.
PCOS & PMDD
Hormonal, metabolic, and inflammatory evaluation that goes well beyond standard gynecologic care. Both are significantly underdiagnosed and undermanaged.
Chronic Fatigue & Fibromyalgia
Multi-system conditions with overlapping hormonal, mitochondrial, and autonomic components evaluated through a functional medicine lens.
Dysautonomia
Autonomic nervous system dysfunction with hormonal and mitochondrial drivers — a condition that rarely resolves with hormone titration alone.
Functional Medicine & Gut Health
Hormonal dysregulation rarely exists without downstream effects on metabolic function, inflammation, and gut health. PHC integrates these systems into a coherent clinical picture.
Advanced Peptide Therapy
Targeted peptide therapy for metabolic function, cognitive performance, mitochondrial health, and tissue recovery — with physician-level evaluation and monitoring.
The Patient Who Isn't Responding
Labs optimized. Protocol appropriate. Still symptomatic. This almost always points to something the original workup didn't capture.
Dr. Darrell Wilcox, MD
Darrell Wilcox, MD specializes in hormone optimization, BHRT, functional medicine, and advanced peptide therapy. He is trained through Worldlink Medical under Neal Rouzier, MD — one of the most rigorous clinical training programs in evidence-based hormone optimization — and is listed on the Worldlink find-a-physician directory.
Dr. Wilcox is licensed in Texas and Arizona, offers telemedicine services to patients across both states, and serves as Medical Director for hormone optimization clinics in Texas and Arizona. His approach is grounded in root-cause clinical reasoning, comprehensive lab evaluation, and honest informed consent — including frank discussion of off-label use, monitoring requirements, and realistic timelines.
