About Liraglutide

Liraglutide is a GLP-1 receptor agonist studied for blood-glucose regulation in type 2 diabetes and for effects on appetite and body weight. Its shorter half-life relative to weekly agents corresponds to commonly reported once-daily use. This entry is informational and is not a recommendation to use the compound.

See the full Liraglutide compound page or the Liraglutide reconstitution calculator, or compare against other compounds on the half-life overview.

Questions, answered.

What is Liraglutide's half-life?
Liraglutide's elimination half-life is approximately 13 hours, based on published pharmacokinetic data. That means about half of a dose is eliminated in that time, half of the remainder in the next interval, and so on.
How long does Liraglutide stay in your system?
Using the ~5-half-lives rule of thumb, a single dose of Liraglutide is roughly 97% eliminated after ~2.7 days. Actual clearance varies with dose history, route, and individual metabolism — treat this as an educational estimate, not a measurement.
Do levels build up with repeated doses?
Yes — if a new dose lands before the previous one is eliminated, the remainders stack. With consistent dosing, estimated levels reach steady state after roughly four to five half-lives. Peptilot's Levels feature stacks this exact curve across your logged doses so you can see the estimate for your own history.
