Regulatory statusFDA-Approved (labeled use)
Published half-life~13 hours
Evidence levelFDA label
CategoryMetabolic / GLP-1

Regulatory status

FDA-Approved (labeled use). FDA-approved for its labeled indications; generic liraglutide is also available.

Reported cautions

⚠ Worth knowing. Boxed warning for thyroid C-cell tumors. Pancreatitis has been reported; gallbladder events appear in the weight-management trials.

Pharmacokinetics

Published figures give an elimination half-life of ~13 hours. FDA label (Victoza/Saxenda) — why it's dosed daily, not weekly.

This figure is tagged FDA label in our evidence system. This figure appears in an approved product's prescribing information, which is the strongest tier in our system — a regulator-reviewed number for a specific approved product. You can see the shape this implies between doses in the Half-Life Visualizer, and compare it against every other compound in the Half-Life Data Table. Our sourcing page explains what each tier means.

Remember that an estimated curve is a model built from a population figure, not a measurement of your blood. Individual clearance varies, and for depot injections the figure describes release from the injection site rather than the compound clearing. Half-life explained →

What Peptide Plug does and does not publish

This page carries regulatory status, general context and published pharmacokinetics. It carries no dose, frequency or cycle information — that is a deliberate editorial line, because dosing is a clinical decision rather than reference data. We also do not sell, supply, source or link to vendors for any compound.

Reference information, not medical advice. This page describes regulatory status and published pharmacokinetics. It does not tell you whether to use this compound, how much to use, how often, or whether it is safe for you. Peptide Plug does not sell, supply or source any compound.
