Master titration schedules for GLP-1 peptides using a structured calculator to safely increase doses and track progression.
# How to Use a GLP-1 Titration Calculator: Semaglutide and Tirzepatide Schedules Semaglutide and tirzepatide are dose-escalating medications. Starting at full dose causes severe side effects; instead, you titrate (gradually increase) over weeks to allow your body to adapt. A titration calculator removes guesswork and ensures you're following evidence-based progression.
GLP-1 peptides slow gastric emptying and reduce appetite aggressively. If you start at 2.4 mg of semaglutide, you'll experience:
By titrating (0.25 mg → 0.5 mg → 1 mg → 1.5 mg → 2 mg → 2.4 mg), your body adapts to each dose level, minimizing side effects while you progress toward therapeutic dose.
Most users titrate over 8-12 weeks, adding 0.25-0.5 mg every 1-2 weeks depending on tolerance.
Step 1: Select Your Peptide
The calculator offers semaglutide, tirzepatide, and sometimes other GLP-1 variants. Choose exactly which one you're using—the titration schedules differ slightly between them.
Step 2: Enter Your Starting Dose
Most users start at 0.25 mg (the lowest available dose). However, if you're restarting after a break or switching between peptides, enter your current dose.
Step 3: Specify Your Target Dose
This is the dose you intend to reach—usually the manufacturer's recommended dose for your indication:
Step 4: Select Your Titration Pace
The calculator adjusts dose escalation accordingly.
Step 5: Review Your Schedule
The calculator generates a week-by-week breakdown:
```
Week 1-4: 0.25 mg once weekly
Week 5-8: 0.5 mg once weekly
Week 9-12: 1.0 mg once weekly
Week 13-16: 1.5 mg once weekly
Week 17+: 2.0 mg once weekly (maintenance)
```
Step 6: Log It
Copy this schedule into MyProtocolStack's injection log. The platform will remind you when it's time to escalate doses and track your side effects week-to-week.
The calculator highlights key moments:
Dose escalation checkpoint: The scheduled day to increase your dose. Don't escalate early unless directed by your healthcare provider. If you're experiencing severe side effects, you can pause at your current dose for an extra week before escalating.
Steady-state windows: After each dose increase, it takes 5-7 days to reach steady-state (your body adjusting to the new dose). The calculator shows this window so you understand why side effects may worsen in days 2-5 after an increase.
Tolerance assessment points: Every 2 weeks, evaluate:
If yes to all, you're ready to escalate. If no, discuss with your provider about extending your current dose another week.
Semaglutide Standard Titration (to 2 mg weekly):
Duration: 16 weeks to reach stable 2 mg dose.
Tirzepatide Standard Titration (to 7.5 mg weekly):
Duration: 8 weeks to reach stable 7.5 mg dose.
Conservative Pace (Semaglutide to 1.5 mg):
Duration: 15 weeks to reach stable 1.5 mg dose (lower final dose, maximum adaptation time).
If you're experiencing severe side effects:
Option 1: Extend current dose 1-2 weeks
Skip the scheduled escalation; stay at 0.25 mg for 5-6 weeks instead of 4. Your body gets more time to adapt.
Option 2: Reduce escalation increment
Instead of jumping 0.25 mg, some pharmacies can provide 0.125 mg increments (very slow escalation). Ask your pharmacy if available.
Option 3: Lower target dose
If you only need 1 mg instead of 2.4 mg, change your target to 1 mg and the calculator adjusts accordingly. Maintenance at 1 mg is perfectly effective for many users.
Always discuss tolerance adjustments with your healthcare provider before deviating from the schedule.
Semaglutide and tirzepatide are measured in milligrams (mg) injected once weekly. The injection typically comes in a pre-filled pen or vial. When the label says "0.5 mg," you're injecting the entire pen or drawing the specified amount from a multi-dose vial.
Don't confuse weekly dose with concentration:
Your calculator and logs should track your actual dose per injection, not vial concentration.
Log each dose escalation with:
Example entry:
```
Week 9 (Semaglutide escalation to 1.0 mg):
```
Mistake 1: Escalating early
You feel good on 0.5 mg and want to hit 2 mg faster. Don't. Follow the schedule. Early escalation causes severe side effects and may force you to pause or reduce.
Mistake 2: Confusing injection frequency
Semaglutide and tirzepatide are once-weekly injections. Don't take daily doses or skip weeks. The calculator assumes once-weekly dosing.
Mistake 3: Not accounting for pharmacy availability
If your pharmacy only stocks 0.25 mg and 0.5 mg pens (not intermediate doses), the calculator may recommend increments your pharmacy can't provide. Verify dose availability with your pharmacy before starting titration.
Mistake 4: Restarting after a break
If you pause your protocol for 2+ weeks, your tolerance resets. Don't re-start at your old dose; step back to the dose you were tolerating and re-titrate slowly.
Titration doesn't mean you must reach the maximum dose. Many users find their optimal dose is 1 mg (semaglutide) or 5 mg (tirzepatide). Once you reach your target dose and feel good, *you don't escalate further*. The calculator helps you find this sweet spot safely.
