Clinical Pharmacist · Functional Medicine Practitioner · Healthcare Entrepreneur
Dr. Michael Nguyen is a Doctor of Pharmacy with 27+ years of clinical experience in sterile compounding, specialty pharmacy, peptide therapy, GLP-1s, and functional medicine. He holds advanced certifications from PCCA and NHIA, and has spent his career developing protocols that address the root causes of metabolic dysfunction — not just the symptoms.
Before founding The Functional Weightloss, Dr. Nguyen helped build a compounding and home infusion company from the ground up into a nationally recognized enterprise with over 250 team members, ultimately acquired for more than $250 million. His clinical focus today centers on peptide therapy, bioidentical hormones, mitochondrial health, and metabolic optimization.
"Peptides work at the signaling level. Rather than replacing hormones or suppressing symptoms, they instruct your body to do what it's already designed to do."— Dr. Michael Nguyen, PharmD, BSPharm
Before starting any protocol — peptide, GLP-1, or functional reset — Dr. Nguyen recommends baseline lab work. Understanding your hormones, metabolic markers, and inflammatory status is the foundation of a personalized approach.
