How to Titrate GLP-1 Medications: Semaglutide and Tirzepatide Schedules

Semaglutide Titration Schedule

Semaglutide is typically dosed weekly via subcutaneous injection.

Standard 16-week titration:

Slower 20-week titration (recommended for GI sensitivity):

The slower schedule reduces gastrointestinal side effects by allowing your gut to adapt to incremental doses.

Tirzepatide Titration Schedule

Tirzepatide is dosed weekly and includes a dual GIP/GLP-1 mechanism.

Standard 16-week titration:

Extended 20-week titration:

Tirzepatide tends to require even slower titration than semaglutide because the dual mechanism increases GI impact. If you're new to GLP-1s, consider the extended schedule.

Why Slow Titration Matters

Your gastric emptying rate and ghrelin physiology need time to adapt to pharmacological appetite suppression. Jumping to high doses too quickly causes:

Slower titration maintains tolerability while preserving appetite for adequate nutrition. Your appetite suppression still works-it's just more gentle.

Signs You Need to Slow Down

You should pause at your current dose for 2-4 additional weeks if:

When you experience these, stay at your current dose for an extra 2-3 dose cycles before advancing. Your body needs more adaptation time.

When to Hold a Dose Entirely

Skip a dose (do not inject that week) if:

Holding one dose doesn't reset your progress; it simply prevents compounding GI stress. Resume the next week at the same dose you skipped.

Lab Checkpoints at Each Tier

At baseline (before starting):

At week 8 (after two dose increases):

At week 16 (after reaching maximum or near-maximum):

Monthly after stabilization:

Dose Adjustment Within Tiers

You don't have to advance exactly on schedule.

Tracking Titration with MyProtocolStack

Log your exact dose each week along with GI symptoms, appetite level (1-10 scale), and weight. MyProtocolStack's tiered tracking shows whether side effects trend downward over 7-10 days at each dose, signaling readiness to advance, or persist, signaling the need to hold.

Titration is a marathon, not a sprint. The goal is reaching an effective dose you can sustain long-term, not the maximum dose. Slow, intentional titration is the surest path to both results and tolerability.
