What is the difference between Liraglutide and Semaglutide?

Liraglutide (Liraglutide (Saxenda / Victoza)) is graded A+ and is FDA-approved for weight management (Saxenda) and type 2 diabetes (Victoza). Semaglutide (Semaglutide (Ozempic / Wegovy)) is graded A+ and is FDA-approved for weight management and type 2 diabetes. They are commonly compared because they share the categories: weight-loss, metabolic.

Which has stronger clinical evidence — Liraglutide or Semaglutide?

On our internal evidence scale, Liraglutide is A+ and Semaglutide is A+. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of Liraglutide vs Semaglutide?

Liraglutide: 0.6–3.0 mg daily (subcutaneous). Semaglutide: 0.25–2.4 mg weekly (subcutaneous injection). Always work with a licensed clinician — peptide dosing should be individualized.

Liraglutide vs Semaglutide

Both Liraglutide and Semaglutide are used for weight-loss and metabolic. Here's how their evidence, dosing, and regulatory status actually compare.

Liraglutide

Evidence A+

Liraglutide (Saxenda / Victoza)

The original once-daily GLP-1 receptor agonist. Lower weight-loss magnitude than semaglutide but a longer real-world track record across diabetes and obesity.

Semaglutide

Evidence A+

Semaglutide (Ozempic / Wegovy)

A GLP-1 receptor agonist and the gold standard for evidence-based weight loss peptide therapy. Demonstrated 14.9–16.9% mean body weight reduction in the landmark STEP trials.
