Dose Range Diabetes (Ozempic): 250-1000 mcg weekly; Weight management (Wegovy): 2400 mcg weekly (after 16-week titration); Oral (Rybelsus): 3-14 mg daily Frequency Once weekly subcutaneous injection Cycle Length Ongoing; dose escalation over 16–20 weeks to maintenance dose Half-Life ~7 days (168 hours), enabled by C18 fatty diacid albumin-binding modification ## Administration Routes Subcutaneous (weekly) Oral (daily) ### Quick Reconstitution Calculator Calculate syringe units instantly Syringe Draw 10.0 units 2500 mcg/ml · 0.100 ml draw Full Tool (https://www.bodyhackguide.co/tools/reconstitution) For laboratory research use only. This tool performs reconstitution math (concentration and syringe-unit conversion) and is not dosing guidance for humans or animals. ## Dosing Protocols Beginner 0.25 mg subcutaneous once weekly for 4 weeks (dose escalation start). Standard Escalate: 0.25mg x4 weeks → 0.5mg x4 weeks → 1mg x4 weeks → 1.7mg x4 weeks. Advanced Full escalation to 2.4 mg weekly (Wegovy® dose) over 16–20 weeks. Maintain at highest tolerated dose. ## Weight-Based Dosing Not weight-based. Fixed dose escalation schedule per FDA labeling. ## 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 (https://www.bodyhackguide.co/compound/tirzepatide) (dual GLP-1/GIP, ~22.5% loss in SURMOUNT-1), Retatrutide (https://www.bodyhackguide.co/compound/retatrutide) (triple GLP-1/GIP/glucagon, ~24% at Phase 2), and Mazdutide (https://www.bodyhackguide.co/compound/mazdutide) (GLP-1/glucagon). Adjuncts that amplify outcomes: Cagrilintide (https://www.bodyhackguide.co/compound/cagrilintide) (amylin analog stacked as CagriSema), AOD-9604 (https://www.bodyhackguide.co/compound/aod-9604) (HGH fragment for abdominal-fat preservation of lean mass), Tesamorelin (https://www.bodyhackguide.co/compound/tesamorelin) (visceral-fat specific GHRH), and Tesofensine (https://www.bodyhackguide.co/compound/tesofensine) (triple monoamine reuptake inhibitor). Oral alternatives: Orforglipron (https://www.bodyhackguide.co/compound/orforglipron) (non-peptide GLP-1). Insulin-sensitizing context: Berberine (https://www.bodyhackguide.co/compound/berberine), Metformin (https://www.bodyhackguide.co/compound/metformin), and NMN (https://www.bodyhackguide.co/compound/nmn). ## Side Effects & Safety Nausea (especially at initiation — dose-dependent), vomiting, diarrhea, constipation, abdominal pain, decreased appetite (therapeutic effect), headache, fatigue, dizziness. Rare: pancreatitis, gallbladder issues, thyroid C-cell tumors (rodent studies). Injection site reactions with subcutaneous formulation. 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).
