Physician-supervised protocols tailored to your goals — recovery, longevity, hormonal optimization, and weight loss.
Peptides are short chains of amino acids that act as signaling molecules in the body — directing processes like tissue repair, hormone production, inflammation regulation, and metabolic function. At Four Peaks Primary Care & Internal Medicine, Dr. Fayz Yar Khan, MD, FACP offers peptide therapy as part of a comprehensive, physician-supervised approach. Unlike online peptide clinics that operate without in-person evaluation, our protocols are based on a full clinical assessment — including lab work, medical history, and a clear understanding of your goals — and are monitored over time.
Peptides We Work With
BPC-157 (Body Protection Compound)
BPC-157 is one of the most studied peptides for tissue repair and recovery. It has demonstrated effects on tendon, ligament, muscle, and gut tissue healing. It is commonly used by patients recovering from orthopedic injuries, dealing with chronic joint pain, or managing gastrointestinal conditions.
Sermorelin / CJC-1295 + Ipamorelin (Growth Hormone Secretagogues)
These peptides stimulate the pituitary gland to produce more growth hormone naturally — rather than introducing exogenous HGH. They are used for patients experiencing age-related decline: poor sleep quality, decreased muscle mass, increased body fat, and low energy. Because they work through the body’s own regulatory mechanisms, they carry a different risk profile than direct HGH supplementation.
GLP-1 Peptides (Semaglutide / Tirzepatide)
GLP-1 receptor agonists are technically peptides and are among the most clinically validated therapies available for weight management and metabolic health. See our dedicated Weight Loss page for full details on physician-managed GLP-1 programs.
PT-141 (Bremelanotide)
PT-141 acts on melanocortin receptors to address sexual dysfunction in both men and women. It works through a different mechanism than PDE5 inhibitors and is one of the few FDA-approved treatments in this category.
Thymosin Beta-4 / TB-500
TB-4 and TB-500 are associated with immune modulation, inflammation reduction, and tissue repair. They are often used alongside BPC-157 for injury recovery or as part of anti-inflammatory protocols.
What to Expect
Initial consultation: Dr. Khan reviews your health history, current medications, and goals. Appropriate lab work is ordered to establish baselines and identify any contraindications.
Protocol design: Based on your evaluation, a peptide protocol is designed — including the specific peptide(s), dosing, administration method, and duration. Most peptides are administered via subcutaneous injection; some are oral or intranasal.
Ongoing monitoring: Follow-up visits and lab checks are scheduled based on your protocol. We adjust as your body responds and your goals evolve.
Why Physician Supervision Matters
The peptide market is largely unregulated. Many online services ship peptides without in-person evaluation, proper lab work, or follow-up monitoring. Some sell research-grade peptides — not pharmaceutical-grade — at doses that may not be appropriate for your situation.
Physician supervision means your protocol is based on an actual clinical evaluation, your baselines are documented so effects can be measured, contraindications are identified before you start, and a licensed physician is accountable for your outcomes over time.

Frequently Asked Questions
Are peptides legal in Arizona?
The peptides we prescribe are legal when prescribed by a licensed physician for clinical use. Some have FDA approval; others are prescribed off-label based on clinical evidence. Dr. Khan will explain the regulatory status of any peptide before it is included in your protocol.
How are peptides administered?
Most peptides are administered via subcutaneous injection using a small needle into the fatty tissue of the abdomen — similar to insulin injections. Some peptides are available in oral, intranasal, or topical forms.
How quickly does peptide therapy work?
This varies by peptide and goal. BPC-157 for injury recovery may show effects within 2–4 weeks. Growth hormone secretagogues typically require 3–6 months to show full effects on body composition and energy.
Does insurance cover peptide therapy?
Most peptide protocols are not covered by insurance and are paid out of pocket. Some items such as initial lab work may be covered depending on your plan.
Do I need to be an existing patient to start peptide therapy?
No. New patients are welcome to book a consultation specifically for peptide therapy evaluation.
