what is a glp-1 treatment Safe for Weight Loss? Peptides, Benefits & Risks Understanding GLP-1 vs. GIP Medications:

Two main incretin hormones have been identified: glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP)

DPP-4 may additionally influence metabolic control via its proteolytic effect on other regulatory peptides, but it has also been reported to affect insulin sensitivity, potentially mediated through its non-enzymatic interactions with other membrane proteins

These peptides are broken down by stomach acid and digestive enzymes before they reach the bloodstream, which negatively impacts the amount your body can absorb

Clearly the brain/central nervous system effect of these drugs is gaining traction and considerable interest
