The book is:

• a comprehensive review of the available peptides for enhancing health and function. 
• for some, an introduction to cellular health and will demonstrate its connection to longevity
• for the most part, each chapter is written as a standalone; that way, the book may be read cover-to-cover, or used as a reference

The book is not suggesting that peptide therapy is the panacea. The patient has a proactive role in their health that includes careful attention to diet, exercise, sleep habits, stress management, and so on. Peptide therapy assists, but should not be considered a form of cure-all magic.
