Identity & type

Molecular type
analog
Origin
A short-acting (daily) GLP-1 agonist — approved for diabetes (Victoza), obesity (Saxenda 3.0 mg) and CV risk (LEADER trial).

Mechanism of action

GLP-1R agonist with an albumin-binding C16 chain (13 h half-life).

Dosing & routes

Official / clinical context

Approved drug — indications, dosing and warnings are defined by the official label. Victoza 1.2–1.8 mg/day; Saxenda titrated to 3.0 mg/day SC.

Regulator-approved labeling and published study designs — never a recommendation.

Community-reported practice

Victoza 1.2–1.8 mg/day; Saxenda titrated to 3.0 mg/day SC. Victoza/Saxenda: moderate weight loss (5–8%), good glycemic control; daily injection — the community has largely moved to weekly analogues.

Unverified self-reports. Not medical advice. Not endorsement.

Expected effects (community)

Victoza/Saxenda: moderate weight loss (5–8%), good glycemic control; daily injection — the community has largely moved to weekly analogues.

Protocol — official vs community

Official / label

Saxenda (obesity): 3 mg SC daily. Victoza (T2D): 0.6–1.8 mg daily.

  1. 01Week 1: 0.6 mg daily
  2. 02Weekly +0.6 mg steps as tolerated
  3. 03Maintenance: 3 mg daily (Saxenda) or 1.2–1.8 mg (Victoza)

Duration: Chronic.

Daily injection; weight loss (~8% mean) is modest versus weekly incretins — largely superseded for obesity.

Community (anecdotal)

Same as label; sometimes reconstituted from research vials.

Cycle:
Continuous.
Break:
None.

Few reasons to choose it over weekly options except cost and availability.

Human evidence

LEADER: −13% MACE; SCALE: −8% weight vs −2.6% placebo.

Preclinical evidence

The preclinical phase was completed and submitted to regulators as part of registration; pharmacology and toxicology details are part of the official label.
