What Is Liraglutide?
Liraglutide is a GLP-1 receptor agonist approved by the FDA for type 2 diabetes (as Victoza) and for chronic weight management (as Saxenda). It is supported by large phase 3 randomized controlled trials, including the LEADER cardiovascular outcomes trial and the SCALE obesity program. It is a once-daily injectable prescription medication.
Is Liraglutide FDA Approved?
Liraglutide is FDA approved.
What Does the Research Show?
As of 2026, there are 9 human randomized controlled trials with a combined 15,000 subjects, and 12 animal model studies. LEADER (cardiovascular) and SCALE (obesity) phase 3 programs show glycemic, weight, and cardiovascular benefits across large populations.

How Is Liraglutide Used in Research?
Mechanism of action. GLP-1 receptor agonism enhancing glucose-dependent insulin secretion, slowing gastric emptying, and reducing appetite.
Half-life. Approximately 13 hours, supporting once-daily dosing.
Storage. Approved product: refrigerate and follow label.
Reconstitution. Approved products are pre-formulated. Reconstitution math applies only to lyophilized material - not medical advice. See the reconstitution calculator — a math tool only, not dosing guidance.
What Does Liraglutide's Evidence Tier Mean?
Liraglutide is rated Tier 1 · RCT Evidence. Supported by human randomized controlled trials. Evidence tiers are a shorthand for how strong the human data is — Tier 1 reflects human randomized controlled trials, while lower tiers rest on observational, animal, or theoretical evidence. A higher tier means more confidence that observed effects are real and caused by the compound rather than by chance or bias. For how to weigh each tier, see our guide to understanding peptide evidence tiers.
How Do You Evaluate Liraglutide Sourcing and Quality?
Because research-chemical Liraglutide is unregulated, sourcing quality varies widely between sellers. Before trusting any supplier, check its reputation and enforcement history in the ranked list of trusted peptide sellers, and look for a batch-specific certificate of analysis (COA) showing third-party HPLC or LC-MS purity testing. Purity claims without a named lab, a batch number, and a method are marketing, not data. If you are reconstituting lyophilized material, the reconstitution calculator handles the arithmetic — it is a math tool only and not dosing guidance.
Where to Buy Liraglutide: Trusted & Verified Sellers
Liraglutide is supplied by specialist research-chemical sellers rather than pharmacies, so where you buy it matters as much as what you buy. The sellers below have published moderator-approved third-party lab results for Liraglutide, ranked by overall reputation score. Always confirm a current batch-specific COA before purchasing.
