For researchers building a comprehensive IGF axis research workflow, the standard approach is to use IGF-1 LR3 as the primary tool for sustained IGF1R activation studies, native IGF-1 for short-pulse studies where IGFBP biology is itself the research question, and DES IGF-1 for the narrow set of experiments requiring receptor activation with rapid washout
Unlike GLP-1 medications, many of today's trending peptides havent been studied in large human trials
