CagriSema combines cagrilintide and semaglutide for 22.7% weight loss in the REDEFINE 1 trial of 3,417 adults, outperforming semaglutide alone by seven points. NDA filed December 2025. GI events hit 80% of participants, the highest rate in the GLP-1 class.

CagriSema comes as a pre-filled pen. No reconstitution, no BAC water, no vial math. Dial to the prescribed dose, inject, done. Store at 2 to 8 degrees Celsius; do not freeze. For the grey-market DIY route (separate cagrilintide plus semaglutide vials), the reconstitution math matters. A 5 mg cagrilintide vial with 2 mL BAC water gives 2.5 mg/mL. For the 0.25 mg starting dose, draw 0.1 mL (10 IU on an insulin syringe). A 10 mg vial with 2 mL gives 5 mg/mL; the same 0.25 mg dose is 0.05 mL (5 IU). Run semaglutide math based on your vial concentration. The 16-week titration is non-negotiable. Four weeks at each step: 0.25, 0.5, 1.0, 1.7, then 2.4 mg per component. Do not skip steps. Community users who rushed titration ended up with severe nausea and often quit entirely. If 1.7 mg is your ceiling, stay there; fewer than two-thirds of REDEFINE 1 participants made it to the full dose, and 1.7 mg still produces meaningful weight loss.
