Herzog Vitality Center

Herzog Vitality Center has served the Plano, Texas community since 2004, providing hormone optimization and peptide therapy under the clinical direction of Garrett Clark, NP. Located in the Dallas-Fort Worth metro area, the clinic focuses on evidence-based interventions for hormone imbalances, metabolic dysfunction, sexual health concerns, and age-related vitality decline. With two decades of experience in functional medicine, Herzog Vitality Center combines diagnostic precision with individualized treatment protocols designed to address the root causes of fatigue, weight gain, muscle loss, and hormonal disruption in both men and women.

Herzog Vitality Center's peptide therapy menu includes Semaglutide, with treatment protocols customized based on individual health goals and lab work. Additional peptide options may be available based on medical necessity and FDA guidelines.

Garrett Clark, NP brings clinical expertise in hormone replacement therapy, peptide prescribing, and metabolic medicine to his patient consultations. His approach emphasizes thorough lab analysis—including comprehensive hormone panels, metabolic markers, and body composition assessments—before initiating therapy. Patients receive detailed explanations of how peptides like CJC-1295 stimulate growth hormone release, how PT-141 activates melanocortin receptors to improve libido, and how GLP-1 agonists such as Semaglutide regulate appetite and insulin sensitivity. This educational component ensures patients understand not just what they are taking, but why specific peptides align with their health objectives.

New patients at Herzog Vitality Center in Plano begin with an initial consultation that reviews medical history, current symptoms, and treatment goals. Lab work is ordered to establish baseline hormone levels, metabolic function, and any contraindications to peptide therapy. Follow-up visits—available both in-person and via telehealth for Texas residents—allow for protocol adjustments, symptom tracking, and ongoing education. The clinic also addresses menopause management with bioidentical hormone replacement, skin care protocols that may include collagen-stimulating peptides, and muscle-building programs combining Ipamorelin with resistance training guidance. This integrative model supports patients dealing with andropause, perimenopause, post-pregnancy hormonal shifts, and age-related performance decline.

Herzog Vitality Center differentiates itself through its longevity in the Plano market and its hybrid care model, which accommodates both local patients seeking in-office consultations and those across Texas who prefer virtual follow-ups after initial assessment. The clinic maintains a focused scope—hormone optimization, peptide therapy, and metabolic health—rather than attempting to cover all areas of functional medicine. This specialization allows for deeper clinical experience with peptides like Tesamorelin for abdominal fat reduction and CJC-1295/Ipamorelin combinations for lean muscle preservation. Patients benefit from a practice that has refined its protocols over 20 years, with a provider who stays current on peptide research and adjusts treatment strategies based on emerging evidence and individual patient response.
