is retatrutide the same as glp 1 vs Tirzepatide (2026): Differences in Weight Loss, Metabol – Revolution Health & Wellness Cagrilintide vs Retatrutide Compared |

GLP-1R alone, as activated by semaglutide, primarily signals through Gs-cAMP and PI3K pathways in beta-cell lines

Individual responses vary substantially based on baseline metabolism and hormonal status

Tirzepatide leads to even more weight loss because its a long-acting version of GLP-1 plus GIP (glucose-dependent insulinotropic polypeptide), which has similar effects

Along these lines, daily oral intake of semaglutide presumably results in an overall similar exposure as the subcutaneously administered semaglutide, but with daily pharmacokinetic peaks and troughs

So you start retatrutide in January, begin losing significant weight by February, and the hair shedding shows up in April or May

Research associates lower body weight with decreased risks of cardiac disease, hypertension, and stroke
