📅 Microdose Schedules

Common Microdose Schedules

Split-dose protocols for semaglutide, tirzepatide, and retatrutide. Daily, twice-weekly, and three-times-weekly options.

⚠️ Important: These are example microdose protocols based on community practice and pharmacokinetic principles — not FDA-approved schedules. Always work with a licensed healthcare provider before microdosing GLP-1s.

Semaglutide Microdose Schedules

Standard semaglutide is dosed once weekly at 0.25, 0.5, 1.0, 1.7, or 2.4 mg. Microdosing splits these into smaller, more frequent injections.

Twice-weekly (most common)

Split your weekly dose in half, inject every 3-4 days. e.g. 0.5 mg/wk → 0.25 mg twice weekly. Smoother levels, similar weekly mg.

Three-times-weekly

Split into thirds, inject Mon/Wed/Fri. e.g. 1.0 mg/wk → 0.33 mg 3×/wk. Even smoother levels.

Daily microdose

Divide weekly dose by 7. e.g. 0.7 mg/wk → 0.1 mg daily. Maximally smooth — effectively eliminates peak/trough swings. Most syringe-handling overhead.

Tirzepatide Microdose Schedules

Standard tirzepatide is once weekly at 2.5, 5, 7.5, 10, 12.5, or 15 mg.

Twice-weekly

e.g. 5 mg/wk → 2.5 mg twice weekly. Common for users sensitive to GI side effects.

Three-times-weekly

e.g. 7.5 mg/wk → 2.5 mg 3×/wk. Good for higher-dose tirzepatide users wanting consistency.

Retatrutide Microdose Schedules

Retatrutide is experimental (Phase 3) — typical research doses are 1-12 mg weekly.

Twice-weekly (most users)

e.g. 2 mg/wk → 1 mg twice weekly. Recommended for retatrutide because of its triple-agonist intensity.
