Kelli Musa

Kelli Musa is the practitioner women find after everyone else has failed them. A functional medicine clinician with two decades of clinical practice, Harvard nutrition credentials, and SSRP certification, Kelli is the founder of Peptides First and the architect of The Metabolic Code, a clinical framework rebuilding how women are evaluated, treated, and tracked through midlife. Her thesis is clinical and inconvenient. Metabolism is the driver. Weight, mood, energy, and hormones are downstream of it. Most women aren’t broken. They’ve been read in fragments by a system that runs five tests in twelve minutes and calls it care. She knows the cost of that system personally. Her mother, Carrie, died at forty-three after being dismissed for years. That story is not a grief narrative. It is the clinical case that built the practice. Today, Kelli has helped thousands of women navigate perimenopause, post-pill recovery, and metabolic adaptation, and her practice does not compete with med spas. It replaces them. She speaks nationally on peptide therapeutics, female longevity, and metabolic medicine, and is currently writing her first book, Ms. Managed.
