Tirzepatide
Gentler on-ramp than retatrutide but a similar shape. Appetite suppression is strong, GI side-effects front-load, and the sweet spot is often found around 5–7.5 mg before diminishing returns.
Weekly injection, titrated every 4 weeks.
Response is very individual — some feel 2.5 mg strongly, others need 10+ mg. Compounded product concentration varies widely.
- Week 1 (2.5 mg)Steady
Barely there — or a lot
The 2.5 mg starter dose is designed to be tolerable. Some feel almost nothing; others get immediate nausea and food aversion. Both are normal.
- mild nausea
- early fullness
- Weeks 2–4Payoff
Finding the rhythm
Injection-day GI symptoms become predictable. Cravings for sweets and alcohol often drop before scale movement does.
- reduced cravings
- smaller portions
- Week 5 (5 mg step-up)Adjustment
First real dose
The step to 5 mg is where most people 'feel it working'. Nausea returns for a few days. Steady weight loss usually begins here.
- Month 3–4Payoff
Sweet spot
Many stall or hold at 5–7.5 mg with excellent results. Higher doses trade extra loss for more side-effects.
- Month 6+Steady
Maintenance mindset
Loss slows to ~0.5–1 lb/week. Sustainability, not speed, becomes the focus. Some cycle down to a maintenance dose.
- —Fatty meals near injection amplify nausea
- —Skipping doses to 'catch up' rarely works — restart low
