Protocol: standard weight management with niacinamide support Goal: Weight loss with enhanced cellular energy support Formulation: Semaglutide 2.5 mg/mL + Niacinamide 2 mg/mL Dose escalation schedule: Weeks 1-4: 0.25 mg semaglutide (0.1 mL) weekly Weeks 5-8: 0.5 mg semaglutide (0.2 mL) weekly Weeks 9-12: 1.0 mg semaglutide (0.4 mL) weekly Weeks 13-16: 1.7 mg semaglutide (0.68 mL) weekly Week 17+: 2.4 mg semaglutide (0.96 mL) weekly, or as tolerated Supporting measures: Protein intake: 1.2-1.6 grams per kg body weight daily (to preserve muscle) Hydration: minimum 2-3 liters water daily Consider additional oral niacinamide (250-500 mg daily) if fatigue persists, with provider approval Monitor energy levels, documenting changes weekly Blood work at baseline and every 3 months: metabolic panel, B vitamins, liver enzymes Expected timeline: Weeks 1-4: Minimal weight loss, adjustment period, possible nausea Weeks 5-8: Weight loss begins to accelerate , appetite suppression strengthens Weeks 9-16: Steady weight loss of 1-2% body weight per month Months 4-6: Continued progress toward goal weight Months 6-12+: Maintenance phase at optimal dose Protocol: enhanced energy focus Goal: Combat fatigue while maintaining weight loss momentum Same dose escalation as above, with these additional measures: Oral niacinamide supplement: 500 mg twice daily (with meals) to boost NAD+ beyond injectable dose CoQ10 supplementation: 100-200 mg daily (supports mitochondrial electron transport chain) Magnesium glycinate: 200-400 mg at bedtime (supports energy production and sleep) B-complex vitamin: daily, to support all energy metabolism pathways Track energy levels on a 1-10 scale daily for the first 8 weeks This enhanced protocol recognizes that the 2 mg injectable niacinamide dose alone may not be sufficient to meaningfully impact NAD+ levels
