Dr. Melissa Grill-Petersen

Dr. Melissa Grill-Petersen is a global authority on peptide therapy and small-molecule medicine, and one of the most trusted clinical educators in the longevity space. For over a decade, she has treated patients directly with peptide therapeutics, and for nearly as long, she has trained the clinicians now bringing that same standard of care into practices around the world. Across thousands of hours of live teaching, clinical mentorship, and curriculum development, she has helped shape how an entire generation of doctors and practitioners understands, prescribes, and delivers peptide-based care.

As Co-Founder and CEO of Peptide University, Dr. Melissa built the platform now recognized as a leading destination for peptide and small-molecule education: training thousands of doctors and practitioners in the clinical science, protocols, and business of running a modern longevity practice. Her work sits at the center of a larger shift: peptides moving from the margins of medicine into a defined, evidence-informed standard of care.

Peptide University is part of the broader ecosystem of Human Longevity Global, the parent organization Dr. Melissa founded to advance human flourishing worldwide. Through the Healthspan Model™, Human Longevity Global provides the scientific and systems framework connecting Peptide University's clinical education to a larger vision: measurable, designed human capacity, across individuals, organizations, and cities.

A TEDx speaker and best-selling author of The Codes of Longevity, Dr. Melissa is known for translating complex peptide science into protocols clinicians can act on with confidence, and for building the education infrastructure that lets that knowledge scale far beyond what any one clinician could teach alone.
