difference between semaglutide and retatrutide vs. Tirzepatide vs. Semaglutide vs tirzepatide vs retatrutide:

Patients seeking GLP-1 therapy should rely on FDA-approved medications with established efficacy profiles, including landmark trials like STEP (semaglutide) demonstrating approximately 15% body weight reduction and SCALE (liraglutide) showing 5-8% weight reduction, along with improved glycemic control in patients with diabetes

Ensuring adequate protein intake, typically 80 to 100 grams daily, supports both muscle preservation during weight loss and optimal brain chemistry

Gradual weight loss typically occurs over time when GLP-1 injections are combined with healthy eating and consistent physical activity

The rationale for stacking the two is that they push GH release through two different pathways GHRH and ghrelin so the pulse should be bigger and more natural-feeling than either compound alone
