Head-to-head comparison of Mazdutide and Orforglipron — mechanism, dosing, side effects, legal status, and pricing.
Mazdutide is a dual GLP-1 / glucagon receptor agonist licensed from Eli Lilly to Innovent Biologics for Greater China. Approved by China's NMPA in June 2025 for chronic weight management and in September 2025 for glycemic control in type 2 diabetes; NOT FDA-approved in the US.
Orforglipron (brand name Foundayo) is Eli Lilly's oral non-peptide small-molecule GLP-1 receptor agonist. Unlike oral semaglutide (Rybelsus), it does not require the SNAC absorption enhancer or fasting/water restrictions — it can be taken any time of day. Not a peptide.

Phase 3 GLORY-1 (Ji et al., NEJM 2025) in 610 Chinese adults with obesity/overweight reported mean weight loss of ~11.0% (4 mg) and ~14.0% (6 mg) vs +0.3% placebo at 48 weeks. Additional Phase 3 programs (GLORY-2 obesity, DREAMS-1/2/3 T2DM) supported the NMPA approvals; a 9 mg supplementary application for moderate-to-severe obesity is under NMPA review.
ATTAIN-1 Phase 3 (n=3,127, non-diabetic obesity): mean body-weight change -11.2% with 36 mg at week 72 vs -2.1% placebo; ~59.6% of the 36 mg arm achieved ≥10% loss (Wharton et al., NEJM 2025). ATTAIN-2 (T2D obesity) and the ACHIEVE program (T2D glycemic control) were also positive. FDA approved April 1, 2026 as Foundayo under the Commissioner's National Priority Voucher program for adults with obesity or overweight with ≥1 weight-related comorbidity — the first oral small-molecule GLP-1 RA approved in the US.
Mazdutide and Orforglipron are both in the Metabolic category and may have overlapping mechanisms. Researchers should review both profiles carefully, understand the mechanisms of action, and monitor the relevant biomarkers when combining compounds in the same class. As always, consult a licensed healthcare provider before making any decisions about combining research compounds.
