The split-dose protocol used by many compounding telehealth clinics is intended to smooth the Cmax peak that drives nausea: tirzepatide has a roughly 120-hour half-life (StatPearls pharmacokinetics) and once-weekly dosing produces a peak 8 to 72 hours post-injection where GI side effects cluster
What to Expect Most patients should think in terms of weeks and months, not days: Early weeks : You may notice less hunger, smaller portions feeling sufficient, and calmer cravings
Typical Beginner Dosage 2040 mcg per day , administered once daily Injected subcutaneously (SQ) or intramuscularly (IM) Best injected post-workout on training days for maximum uptake Cycle length: 46 weeks , followed by equal time off Higher doses (50100 mcg) are used by advanced users but increase the risk of insulin resistance and IGF-related side effects
