Masters Medspa — Irvine, Orange County CA
Medical Weight Loss
Peptide Therapy | Hormone Therapy | Metabolic Wellness
Sustainable weight loss is not about willpower — it's about biology. At Masters Medspa, our clinically supervised programs are designed to work with your body's natural metabolic processes, helping you achieve meaningful, lasting results through personalized peptide therapy, hormone optimization, and metabolic wellness support.
Weight loss is deeply personal — and it's rarely as simple as diet and exercise alone. Hormonal imbalances, metabolic dysfunction, stress, sleep disruption, and genetic factors all play a significant role in how your body stores and burns fat. Our programs address the root causes, not just the symptoms.
Every program begins with a thorough lab panel and one-on-one consultation with our licensed clinical team. We monitor your progress closely and adjust your protocol as needed — because what works at month one may need to evolve at month three. Your results are our ongoing commitment, not a one-time prescription.
Weight Loss & Metabolic Support
Peptide Therapy
Peptide therapy is among the most significant advances in medical weight management in recent years. Peptides are short chains of amino acids that act as biological messengers in the body — when used therapeutically, they can support appetite regulation, metabolic function, insulin sensitivity, and fat metabolism, resulting in consistent and sustainable weight loss.
At Masters Medspa, peptide therapy is prescribed and monitored by our licensed clinical team as part of a comprehensive metabolic wellness protocol. Protocols are tailored specifically to your labs, health history, and goals — and may be combined with hormone therapy and NAD for a fully integrated approach to weight and wellness.
Peptides used in metabolic wellness support growth hormone secretion, fat metabolism, lean muscle preservation, energy, and cellular repair. Pricing and protocol duration vary based on individual needs and are determined at your initial consultation.

Cellular Energy & Metabolic Health
NAD Therapy
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of the body that plays a central role in energy production, DNA repair, and cellular metabolism. NAD+ levels naturally decline with age — contributing to fatigue, cognitive decline, slower metabolism, and reduced cellular repair capacity.
NAD therapy replenishes these declining levels, supporting mitochondrial function, boosting energy and mental clarity, improving metabolic efficiency, and enhancing the body's ability to repair and regenerate at the cellular level. Many patients report significant improvements in energy, focus, mood, and overall vitality following a course of NAD treatments.
At Masters Medspa, NAD is available as an IV infusion for rapid, comprehensive cellular delivery — or as a monthly injection series for ongoing metabolic and longevity support. NAD therapy pairs exceptionally well with both peptide therapy and hormone optimization for a fully integrated wellness protocol.
