• Receptor Activation:
• 98% GLP-1 saturation
• 93% GIP activation
• Therapeutic Sweet Spot: Achieves maximum glycemic control + weight loss
• Steady-State: Reached after 4 consistent doses (28 days)
Advanced Administration Protocol
Injection Science:
• Optimal Timing: Wednesday PM (peaks Friday-Saturday)
• Site Performance:
• Abdomen: 94% bioavailability
• Thigh: 89% bioavailability
• Arm: 86% bioavailability
Temperature Management:
• Pre-injection warming to 25°C (77°F) reduces viscosity by 30%
• Never freeze (causes protein aggregation)
Precision Monitoring
Essential Labs:
• Monthly:
• FGF-21, adiponectin
• Liver elastography (FibroScan)
• Quarterly:
• DEXA scan (lean mass preservation)
• RMR testing
