Dr. Crozier is leading the way across the country in the development of peptide treatments. He is a sought after lecturer on peptides and is increasingly finding innovative ways to use peptides to treat his own patients. Peptides are an exciting area of medicine and can be used for anti-aging, immune function, gut healing, tissue repair, and even more serious illnesses and diseases.

A peptide is a short chain of amino acids that are linked together, and can be thought of as a small protein. To date, over 7,000 naturally-occurring peptides have been identified. In our bodies, these small proteins typically act as signaling molecules. They bind to receptors on the cell surface and tell other cells and molecules what to do.

Peptide therapy, or the use of specific peptides in treatment, has gained great popularity in recent years. This is due largely to the fact that these peptides are highly specific (i.e., only do what you want them to do) while also being well-tolerated and safe. There over 60 US FDA-approved peptide medications, 100+ peptide drugs being evaluated in clinical trials, and 500+ in pre-clinical development. Dr. Crozier holds advanced Certification in Peptide Therapy.

Most of these peptide drugs are administered intradermally, but can also come in the form of transdermal creams, nasal sprays, and oral tablets.
