GLP-1 and GLP-2 Orchestrate intestine integrity, gut microbiota, and immune system crosstalk
It has multiple actions including: potentiation of glucose-mediated insulin secretion mechanisms identified: increased -cell proliferation, resulting in an increase -cell mass (Fusco et al, 2017) stimulation of insulin biosynthesis at the translational level, helping to maintain -cell insulin stores and secretory capacity (Baggio & Drucker, 2007) because the GLP-1 effect is glucose-dependent (there is more insulin release when glucose levels are elevated, but less effect when glucose levels are normal), GLP-1 agonists have a lower risk for producing hypoglycemia compared to sulfonylureas (that chronically stimulate insulin release, independent of glucose concentration) suppression of postprandial glucagon release Evidence indicates that stimulation of pancreatic cells by GLP-1 increases their glucose sensitivity, resulting in less glucagon release at any glucose level (Baggio & Drucker, 2007)

Both preclinical and clinical studies have demonstrated that GLP-1s modulate the gut microbiota composition by delaying gastric emptying and altering luminal glucose ( Firmicutes Lachnospiraceae and Clostridiales ), alongside an increase in Proteobacteria (e.g., Burkholderiales bacterium YL45 ) and Akkermansia muciniphila a species largely associated with high-fibre diets and mucosal barrier health (6971)
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure

Instead of asking how high the dose can go, the question becomes: Whats the lowest dose that still delivers benefits
