Going Grey A Guide to Modern Day Peptides

Going Grey: A Guide to Modern Peptide Research is a clear, positive, and research-focused guide for readers who want to better understand the rapidly growing world of peptide science.
Peptides have become one of the most discussed areas in modern biological research. From BPC-157, TB-500, GHK-Cu, MOTS-c, SS-31, and NAD+ to GLP-1 compounds, tirzepatide, retatrutide, cagrilintide, mazdutide, and emerging multi-agonist research, the field continues to evolve quickly. Public interest is high, but online conversations often blur the line between real science, early research, clinical development, and exaggerated marketplace claims.
This book was written to make the subject easier to understand.
Inside, readers will find 40+ peptide and peptide-adjacent research profiles explained in plain language. Each profile explores the compound’s origin, history, research interest, mechanism of interest, positive research themes, notable findings, analytical quality considerations, and responsible interpretation.
Special attention is given to the GLP and metabolic research revolution, including GLP-1, GIP, glucagon, amylin, semaglutide, tirzepatide, retatrutide, and the rise of dual and triple agonist design. The book also explains why glucagon matters, how COAs are read, what HPLC and LC-MS testing mean, and how to separate scientific evidence from social media hype.
Going Grey is not a dosing book, protocol manual, or medical guide. It is an educational reference for readers interested in peptide science, research literacy, analytical testing, and the modern peptide marketplace.
For anyone trying to understand the grey area between emerging research, public curiosity, pharmaceutical development, and peptide-market claims, Going Grey offers a clear and responsible starting point.
