GI adaptation: Lower doses allow the digestive system to adjust, reducing nausea and vomiting Triple receptor activation: Retatrutide's unique GLP-1/GIP/glucagon mechanism requires gradual introduction Safety monitoring: Assess individual response before increasing to therapeutic doses Injection site tolerance: Verify no local reactions before committing to higher doses What to Expect in the First Week During the initial retatrutide dose, you may experience: Mild appetite reduction (typically noticeable by days 2-3) Possible nausea, especially with large or fatty meals Minor injection site reaction (redness, mild swelling) Increased satiety after smaller portions Important: Don't be discouraged if you don't see significant weight loss at 2mg
