Receptor logic
GIP / GLP-1 dual agonist
Dual incretin agonism. GIP component improves the side-effect ceiling vs pure GLP-1, allowing higher effective exposure.
What to watch
Titrate in 2.5 mg steps every 4 weeks. GI tolerance is the rate limiter, not efficacy.
Stacks with
Often the GLP-1 backbone; cycle off-ramps matter to preserve lean mass.
