Peptide therapy uses targeted amino acid sequences to support the body's own healing, performance, and recovery, a science-backed wellness approach that works from the inside out.
At Nashville Plastic Surgery Institute, world-class surgical results have always been only part of the picture. Under the leadership of board-certified plastic surgeon Dr. Jacob Unger, a published researcher, international lecturer, and co-founder of a plastic surgery biotech company, NPSI's Wellness Collection brings the same commitment to evidence-informed care into the recovery and longevity space. Peptide therapy is a natural extension of that philosophy: precision-driven, medically supervised, and designed to complement your aesthetic results from the inside out.
Depending on the formulation, peptide therapy may support:
Peptide therapy uses short chains of amino acids that act as biological messengers in the body to trigger targeted responses such as tissue repair, improved metabolism, better sleep, and reduced inflammation. It works by supporting natural cellular communication rather than overriding it.
Peptides bind to specific cellular receptors and signal targeted biological processes such as growth hormone release, tissue repair, metabolic regulation, cognitive support, and inflammation reduction. This allows for precise, pathway-specific effects with minimal impact on other systems.
Depending on the formulation, peptide therapy may support faster recovery, improved body composition, increased energy and vitality, better sleep, enhanced cognitive function, improved mood, healthier skin and collagen production, and gut health support.
Good candidates include individuals recovering from surgery, those experiencing low energy or poor sleep, people seeking improved body composition or fat metabolism, those wanting cognitive or mood support, and active individuals focused on performance and recovery. Candidates should generally be in good health and not pregnant or breastfeeding.
At NPSI, peptide therapy is typically self-administered at home via subcutaneous injection. Patients receive full instruction and guidance from a licensed medical provider before beginning treatment to ensure safe and proper use.
Most peptide therapy protocols run for 8 to 12 weeks, followed by a 12-week break before resuming. Some peptides such as NAD+, GHK-Cu, and glutathione may be used on a longer-term or ongoing basis depending on provider guidance.
Many patients notice improved sleep and energy within 1 to 2 weeks. By weeks 3 to 4, early changes in recovery and body composition may appear. More noticeable improvements in focus, vitality, and healing typically develop between weeks 6 and 12.
When medically supervised and properly prescribed, peptide therapy is generally considered safe and targeted in its action. However, all treatments should be reviewed by a licensed provider, and individual results and responses may vary.
No. Peptide therapy is not intended to diagnose, treat, cure, or prevent any disease. It is a wellness and recovery-focused approach designed to support the body's natural processes under medical supervision, and individual results may vary.
