A
Liraglutide
B
Semaglutide
A side-by-side look at what Liraglutide and Semaglutide actually are, so you can see where they overlap and where they genuinely differ before deciding which is worth researching further — no score, no “winner,” just the facts next to each other.
FDA status
Liraglutide
FDA-approved — Victoza (type 2 diabetes, 2010) & Saxenda (chronic weight management, 2014), both now with multiple FDA-approved generic versions
Semaglutide
FDA-approved — Wegovy & Ozempic (the compounded version this board ranks is not independently FDA-reviewed)
Typical dose / use
Liraglutide
Up to 1.8 mg/day SC (Victoza, type 2 diabetes) or 3.0 mg/day SC (Saxenda, weight management) — both FDA label doses
Semaglutide
0.25–2.4 mg/week (FDA label range)
Product forms
Liraglutide
Injectable — pre-filled, multi-dose solution pen; no reconstitution step for any FDA-approved product
Semaglutide
Injectable; also an oral tablet (Wegovy)
How it works
Liraglutide
Activates the GLP-1 receptor alone, structurally modified to extend native GLP-1's 1.5–2 minute half-life to about 13 hours — enough for once-daily dosing, versus semaglutide's further-modified, roughly week-long half-life that allows once-weekly dosing.
Semaglutide
Activates the GLP-1 receptor alone — one target, versus tirzepatide's two — slowing gastric emptying, boosting insulin release when blood sugar is high, and reducing appetite.

Every fact above is reused from Liraglutide's own research article and Semaglutide's own compound guide, not re-derived here. A highlighted value means that number is objectively larger or smaller — more providers ranked, a lower standing price — never a claim about which compound is “better.” Cost and provider counts are read live from each compound's own board and can change without notice.
