Tirzepatide & Semaglutide Dosing Made Simple: A clear, practical guide to understanding your weekly dose
A Better Way to Understand Your Medication
If you’re taking Semaglutide or Tirzepatide, you’ve likely asked yourself at some point:
“Am I taking the right amount?”
“What do these units actually mean?”
You’re not alone—and more importantly, you’re not expected to figure it out without guidance.
Dosing can feel confusing at first because you’re working with three different measurements at once:
Milligrams (mg)
Milliliters (mL)
Units on a syringe
But once you understand how they connect, everything becomes simple, predictable, and easy to manage.
✨ Think of it this way: mg tells you what you need, units tell you how to measure it.
The Two Numbers That Matter Most
Every dose comes down to two essential pieces of information:
Your Dose (mg)
This is the actual amount of medication your body receives.
Your Injection (units)
This is simply how that dose is measured and delivered.
Once you understand how to move between these two, you’re in full control of your dosing.
Why Starting Low Matters
Both medications are designed to be introduced gradually.
This approach—called titration—is what allows you to:
Minimize side effects
Improve tolerance
Achieve steady, sustainable results
Before You Increase Your Dose, Ask Yourself:
1. Have I been on this dose for at least 4 weeks?
Your body needs time to adjust. Moving too quickly can lead to unnecessary side effects.
2. Am I experiencing side effects?
If the answer is yes, stay where you are. Increasing your dose will usually make symptoms worse—not better.
3. Am I losing weight consistently?
A healthy target is:
1.5 – 2 pounds per week
If you’re hitting this range, your dose is already working.
⚖️ The goal is not the highest dose—it’s the right dose.
Understanding Concentration (The Key to Everything)
Each vial has a concentration, written as:
mg per mL (mg/mL)
This tells you how strong your medication is.
And here’s the critical conversion:
💡 1 mL = 100 units on an insulin syringe
How to Convert mg → Units
This is the most common calculation—and it’s simpler than it looks.
The Formula
Dose (mg) ÷ Concentration (mg/mL) = mL
mL × 100 = Units
Example: Semaglutide
Dose: 0.25 mg
Concentration: 5 mg/mL
0.25 ÷ 5 = 0.05 mL
0.05 × 100 = 5 units
✔️ You would inject 5 units
How to Convert Units → mg
If you only know your dose in units, you can reverse the process.
The Formula
(Units ÷ 100) × Concentration = mg
Example: Tirzepatide
Units: 44
Concentration: 17 mg/mL
(44 ÷ 100) × 17 = 7.5 mg
✔️ You are taking 7.5 mg
Semaglutide Dosing Guide (5 mg/mL)
0.25 mg (5 units) — Weeks 1–4
0.5 mg (10 units) — Weeks 5–8
1 mg (20 units) — Weeks 9–12
1.7 mg (34 units) — Weeks 13–16
2.4 mg (48 units) — Maintenance
Tirzepatide Dosing Guide (17 mg/mL)
2.5 mg (15 units) — Weeks 1–4
5 mg (30 units) — Weeks 5–8
7.5 mg (45 units) — Weeks 9–12
10 mg (60 units) — Weeks 13–16
12.5 mg (74 units) — Weeks 17–20
15 mg (88 units) — Maintenance
What Most People Get Wrong
It’s easy to assume that increasing your dose faster will lead to faster results.
In reality:
Higher doses don’t guarantee better outcomes
Side effects can slow your progress
Consistency always beats speed
🚫 More is not better. Better is better.
A Smarter, Sustainable Approach
The patients who see the best results tend to follow a simple pattern:
Stay consistent with weekly injections
Give each dose time to work
Only increase when necessary
Focus on steady progress—not rapid changes
Final Thoughts
Dosing doesn’t have to feel overwhelming.
Once you understand the relationship between mg, mL, and units, everything becomes clear—and manageable.
✨ “Life is complicated—but medicine makes sense.”
And once you see how it all fits together, it truly does.
