Physician-led hormone replacement and GLP-1 weight management, designed around your labs, not a template. Led by Dr. Gregory Allen, board-certified and practicing in Mesa for 18 years. In-person in Mesa or by secure virtual visit nationwide.
Outcome figures reflect Tera Fe patient averages. Individual results vary; treatment eligibility is determined by a licensed physician.
We don't start with a medication. We start with a full diagnostic workup, and we only prescribe what your body — and the data — actually calls for.
For women navigating peri- and post-menopause and men noticing low energy, mental fog, lost muscle, or a flatter mood. We rebalance what's depleted using bioidentical hormones matched to your panels.
Programs start at a transparent monthly membership — labs and refills bundled.
Explore HRT →Physician-supervised semaglutide and tirzepatide, paired with the hormonal workup most weight-loss clinics skip. Because "it won't come off" is often a thyroid or cortisol story, not a willpower one.
Bundled membership: consult + medication + check-ins in a single price.
Explore GLP-1 →Because how you feel and how you look are part of the same story. Board-certified injectors, CO₂ laser resurfacing, NAD+ & IV therapy, and medical-grade skincare (ZO, SkinBetter Science, Face Reality) curated by Dr. Allen.
Free consultation. Transparent per-unit and per-treatment pricing.
Explore aesthetics →Because the #1 complaint in this category is "I didn't know what I was paying for." We fixed that.
Tell us what you're feeling, what you've tried, and what you want to change. We'll tell you whether HRT, a GLP-1 protocol, or both are worth exploring.
Labs drawn in our Mesa office or at the nearest LabCorp or Sonora Quest, a symptom deep-dive, and a medical-history review. Every plan is built on data, not intuition.
Dr. Allen personally reviews your labs line by line and designs a plan around your specific needs — the right protocol, the right dose, the right pace — to get you optimized and feeling your best.
Now that you're on the journey back to your best self, you'll need follow-up and proper care to make the results last — and this is where Tera Fe is genuinely best in class. Nurse practitioners, registered nurses, and skilled support staff are here between every lab, every titration, and every check-in. Your hormone membership is the relationship that makes it worth it.
Dr. Gregory Allen is board-certified in Family Medicine and founded Tera Fe in 2008 after watching conventional medicine let too many of his patients down on hormones and metabolism. In the years since, he's trained with national leaders in bioidentical HRT, lectured at anti-aging conferences around the country, and built a practice where patients actually get answers — not a five-minute visit and a dismissive shrug.
That's the difference between a quick-convert telehealth brand and Tera Fe: one doctor personally reviewing your labs, a consistent team that knows your name, and a protocol refined over thousands of patients — not a thousand different clinicians.
Averages drawn from our own active-patient panel. Your results will be shaped by your labs, adherence, and care plan.
Most complaints in this category are about pricing confusion. We priced Tera Fe so you see the whole picture before you commit a dollar.
Eighteen years of physician-led care, thousands of patients, and one quiet goal: helping you feel like yourself again. Dr. Allen and the Tera Fe team are in this with you — for as long as the work takes.
When prescribed and monitored by a physician using lab-based dosing, bioidentical HRT has a strong safety profile supported by decades of clinical research. Tera Fe's protocol emphasizes the lowest effective dose for the shortest medically appropriate duration, with quarterly follow-up labs included. We'll walk you through your specific risks and contraindications during your consult.
Yes. We work with licensed U.S.-based 503A compounding pharmacies that produce sterile, physician-prescribed semaglutide and tirzepatide. These are not branded products (Wegovy®, Ozempic®, Zepbound®, Mounjaro® are registered trademarks of their respective manufacturers), but they are the same active molecules, prepared under a pharmacist's oversight and tailored to your prescribed dose. Compounded drug products are not reviewed for safety, effectiveness, or quality by the FDA.
Most hormone therapy patients report meaningful improvement in sleep, energy, and mood within 4–8 weeks, with cumulative benefits continuing for 6+ months. GLP-1 patients typically see their first weight movement within 3–4 weeks, with the sharpest changes at months 2–4. We benchmark you against your baseline, not against averages.
No. We offer in-office care for Mesa, Chandler, Gilbert, Tempe, and greater Phoenix patients. Everywhere else — inside Arizona or out of state — you can do your consults by HIPAA-compliant secure video, have medications shipped to you, and drop in at the nearest LabCorp or Sonora Quest for labs. If your treatment includes an in-office procedure (pellet insertion, certain aesthetic treatments), you're welcome to fly in for the day — many of our out-of-state patients do exactly that.
For many patients, yes — and it's often more effective than either alone. Weight gain after 40 is frequently a hormonal story (thyroid, cortisol, estrogen, testosterone) layered on top of a metabolic one. Dr. Allen's team is uniquely set up to treat both at once because that's how the underlying physiology actually works.
You pay nothing if we can't help you. The 3-minute quiz is free, your records review is free, and if your labs or history make you clinically ineligible for a specific protocol, we'll tell you straight — and recommend a path that makes sense for you. We'd rather say no than prescribe something that isn't right.
Those are direct-to-consumer telehealth platforms built around scale — hundreds of clinicians, templated protocols, and a short async consult. Tera Fe is a physician-led practice: one doctor who personally oversees every protocol, an 18-year track record, and a local-plus-virtual footprint. If you want a brand, go there. If you want a doctor who knows you, come here.
No payment. No commitment. Just an honest read on what's going on and what we'd recommend.
