Dosing Protocols
0.25 mg subcutaneous once weekly for 4 weeks (dose escalation start).
Escalate: 0.25mg x4 weeks → 0.5mg x4 weeks → 1mg x4 weeks → 1.7mg x4 weeks.
Full escalation to 2.4 mg weekly (Wegovy® dose) over 16–20 weeks. Maintain at highest tolerated dose.
Weight-Based Dosing
Commonly Stacked With
Clinically studied in combination with cagrilintide (CagriSema). Not typically stacked in research community. Avoid combining with other GLP-1 agonists.
Related Compounds — Deeper Research Paths — Semaglutide is the reference GLP-1 mono-agonist. Newer-generation alternatives with higher weight-loss efficacy: Tirzepatide (dual GLP-1/GIP, ~22.5% loss in SURMOUNT-1), Retatrutide (triple GLP-1/GIP/glucagon, ~24% at Phase 2), and Mazdutide (GLP-1/glucagon). Adjuncts that amplify outcomes: Cagrilintide (amylin analog stacked as CagriSema), AOD-9604 (HGH fragment for abdominal-fat preservation of lean mass), Tesamorelin (visceral-fat specific GHRH), and Tesofensine (triple monoamine reuptake inhibitor). Oral alternatives: Orforglipron (non-peptide GLP-1). Insulin-sensitizing context: Berberine, Metformin, and NMN.
Side Effects & Safety
Contraindications
Personal or family history of medullary thyroid carcinoma (MTC). Multiple endocrine neoplasia syndrome type 2 (MEN 2). History of pancreatitis. Severe gastrointestinal disease. Type 1 diabetes. Pregnancy or breastfeeding. Eating disorders (may exacerbate restriction).
Additional Notes
FDA-approved as Ozempic® (diabetes, max 2mg) and Wegovy® (obesity, max 2.4mg). Slow dose escalation is CRITICAL to minimize GI side effects. Inject same day each week. Can change injection day if needed (minimum 48 hours between doses). Store refrigerated before first use.
