Fix Your Hormones & Wellness Weight Loss operates as a Phoenix-based internal medicine and metabolic health practice under the medical direction of Dr. Marvin Riske, a board-certified Internal Medicine physician. The clinic integrates bioidentical hormone replacement therapy (BHRT) with peptide-based interventions and pharmaceutical weight management protocols to address hormonal imbalances, metabolic dysfunction, and age-related decline in adult patients throughout Arizona. Dr. Riske's approach combines diagnostic hormone panels with individualized treatment plans designed to restore physiologic hormone levels and improve metabolic markers in patients experiencing symptoms of andropause, menopause, thyroid dysfunction, and insulin resistance.
The clinic's peptide therapy program centers on NAD+ (nicotinamide adenine dinucleotide) supplementation and Semaglutide for metabolic optimization. NAD+ therapy is administered to support cellular energy production, mitochondrial function, and DNA repair mechanisms that decline with aging, while Semaglutide—a GLP-1 receptor agonist—is prescribed for weight reduction and glycemic control in qualifying patients. Dr. Riske utilizes Semaglutide as part of comprehensive weight loss programs that include nutritional counseling, metabolic monitoring, and body composition analysis. Patients typically undergo baseline laboratory testing including comprehensive metabolic panels, lipid profiles, hemoglobin A1c, and hormone assays before initiating peptide protocols, with ongoing monitoring to assess treatment response and adjust dosing parameters.
Dr. Marvin Riske brings internal medicine training to the functional and regenerative medicine space, allowing him to manage complex patients with multiple comorbidities including diabetes, hypertension, and cardiovascular risk factors alongside hormone optimization. His clinical model emphasizes root-cause analysis of metabolic disorders rather than symptom suppression alone. Patients receive detailed consultations that review medical history, current medications, lifestyle factors, and treatment goals before developing hormone replacement or peptide therapy plans. The practice maintains protocols for monitoring potential side effects, contraindications, and drug interactions specific to peptide and hormone therapies in medically complex populations.
Patients at Fix Your Hormones & Wellness Weight Loss in Phoenix can access care through in-person visits at the clinic's Arizona location or via telehealth consultations for established patients and follow-up appointments. Initial consultations typically involve comprehensive health assessments, discussion of symptoms such as fatigue, weight gain, low libido, cognitive decline, or mood changes, and ordering of appropriate laboratory work. Treatment plans may combine BHRT using testosterone, estrogen, progesterone, or thyroid hormones with adjunctive peptide therapies based on individual patient needs and lab findings. The clinic provides ongoing patient education regarding injection techniques for self-administered peptides, expected timelines for clinical improvement, and lifestyle modifications that enhance treatment outcomes.
What distinguishes this Phoenix practice is Dr. Riske's dual focus on hormone restoration and evidence-based weight management within an internal medicine framework. Rather than operating as a standalone wellness spa or anti-aging clinic, Fix Your Hormones & Wellness Weight Loss functions as a medical practice capable of managing patients with metabolic syndrome, prediabetes, obesity, and age-related hormone deficiency under physician supervision. The integration of Semaglutide weight loss protocols with NAD+ therapy and comprehensive hormone replacement allows the clinic to address multiple aspects of metabolic health simultaneously. Patients benefit from a physician-led model that can coordinate care with other specialists, interpret complex lab results, and modify treatments based on individual response patterns and emerging health concerns.
