The Complete Guide to GLP-1 Dosing
Accurate dosage charts, week-by-week titration schedules, and an interactive mg-to-units calculator for tirzepatide, semaglutide, and research peptides. Backed by FDA prescribing information.
Reference-grade dosing information
Designed for patients, caregivers, and healthcare providers who need clear, accurate dosing data without the jargon.
Titration Charts
Week-by-week dose escalation schedules based on FDA-approved prescribing information, with initiation through maintenance doses clearly laid out.
mg ↔ Units Calculator
Interactive converter for compounded GLP-1 medications. Enter your vial concentration and dose — get the exact number of units to draw on your syringe.
Injection Guidance
Site-rotation guides for the abdomen, thigh, and upper arm. Technique tips, storage instructions, and common side effects explained clearly.
Dose Calculator
Convert any mg dose to insulin-syringe units for your specific vial concentration.
mg ↔ Units Dose Calculator
Convert between milligrams and insulin-syringe units for compounded GLP-1 medications. Uses a standard U-100 syringe (100 units = 1 mL).
2.5 mg at 2.5 mg/mL → 1.000 mL → 100 units on a U-100 (100-unit / 1 mL) insulin syringe
Always verify calculations with your prescribing provider or pharmacist before administering any medication. This calculator is for reference only.
