Tirzepatide comes in 5 mg or 10 mg freeze-dried vials. Add 1 to 4 ml bacteriostatic water to reconstitute. I like 5 mg/ml for most people. Keeps the math dead simple for weekly doses.
Tirzepatide reconstitution step-by-step
You'll need a 10 mg tirzepatide vial, bacteriostatic water, alcohol swabs, a 3 ml syringe with 18-gauge needle for mixing, and insulin syringes for drawing doses.
- Swab the vial tops with alcohol.
- Draw 2 ml bacteriostatic water into the 3 ml syringe.
- Inject it slowly along the vial wall. Don't blast the powder.
- Let it sit 10 minutes. Roll gently to dissolve. Skip the shaking.
- Now you have 10 mg in 2 ml, or 5 mg/ml. Keep it in the fridge at 2 to 8 C. Good for 28 days.
For a 5 mg vial, add 1 ml water. Same 5 mg/ml concentration. Doses break down like this:
- 2.5 mg = 0.5 ml (50 units on a U-100 insulin syringe)
- 5 mg = 1 ml (100 units)
- 7.5 mg = 1.5 ml (150 units)
- 10 mg = 2 ml (200 units, so two syringes or a 3 ml syringe for the shot)
Use 29- or 31-gauge insulin pins to draw. Inject subQ into your abdomen, thigh, or upper arm. Rotate spots every time.
Want smaller volumes? Add 1 ml water to a 10 mg vial for 10 mg/ml. Then 2.5 mg is 0.25 ml (25 units). But honestly, 5 mg/ml cuts down on mistakes if you're new to this.
Pro tip: Label your pre-filled syringes with a label maker. Or hit up our tirzepatide calculator to figure volumes on the fly.
Tirzepatide titration schedule
Start low. Nausea is the big killer here, and it hits hard if you rush. Research backs this ramp-up:
- Weeks 1 to 4: 2.5 mg once weekly. Pick a day and stick to it.
- Weeks 5 to 8: 5 mg weekly.
- Weeks 9 to 12: 7.5 mg weekly.
- Weeks 13+: 10 mg weekly. Push to 12.5 mg or 15 mg only if it sits well.
Run 16 to 24 weeks at your maintenance dose. Then taper down or take a break. Bump up only after two weeks with zero gut trouble.
I do Monday mornings. The 5-day half-life means levels peak around day 2 or 3, bottom out by day 7. You hit steady state after four shots.
Nausea strikes? Drop back 2.5 mg for a week or two. Slam water, eat light before injecting. Ginger tea 30 minutes prior does wonders.
Some guys under 100 kg jump to 5 mg week one. Fine if you're stacking carefully. But 2.5 mg start is safer.
Tirzepatide peptide cycle lengths and breaks
Give it at least 12 weeks. That's when the fat loss data really shows up. Appetite kill builds over four weeks. Sweet spot is 20 to 24 weeks.
- Short cycle: 12 weeks (up to 7.5 mg), 8 weeks off.
- Standard: 24 weeks (to 10-15 mg), 12 weeks off.
- Extended: 36 weeks with bloodwork every 8 weeks, 16 weeks off.
Off-cycle hunger can rebound. Taper with 1 mg semaglutide weekly if it gets bad. Our semaglutide calculator has you covered.
Track weekly weight, keep fasting glucose under 100 mg/dl, check liver enzymes. With the half-life, it clears in about 25 days after your last pin.
Post-cycle, AOD-9604 at 300 mcg daily for four weeks helps lock in gains. Use the AOD-9604 calculator for exact doses.
Managing sides and half-life impact
That 5-day half-life builds levels with weekly pins. No daily hassle like CJC-1295/Ipamorelin. Downside: sides stick around longer.
Expect nausea the first month (hits 40% of people), some fatigue, slower stomach emptying. Counter it:
- 25 mg famotidine before dosing.
- 10 mg metoclopramide if you're puking.
- Split early doses: 1.25 mg Mon/Thu during ramp-up.
Pancreatitis is rare. Stop immediately for bad abdominal pain. Gallbladder stuff under 1%. Dehydration worsens constipation, so chug 4 L water a day.
Get baseline bloodwork: HbA1c, lipids, amylase, lipase, ALT/AST. Repeat at week 12.
Women, try pinning after ovulation. Cuts nausea. Guys, no worries.
Stacking tirzepatide with other peptides
Tirzepatide alone drops 15-20% body fat in six months. Stacks make it better.
- BPC-157: 500 mcg daily subQ for gut repair. Slashes nausea by half. BPC-157 calculator.
- Semaglutide hybrid: 2.5 mg tirz + 0.5 mg sema weekly first four weeks. Semaglutide calculator.
- TB-500: 2.5 mg twice weekly for inflammation. TB-500 calculator.
- GHK-Cu: 1 mg daily topical or subQ for tighter skin. GHK-Cu calculator.
- CJC-1295/Ipamorelin: 100/100 mcg nightly for GH pulse and muscle keep. CJC-1295/Ipamorelin calculator.
Skip PT-141. Both slow your gut, doubles the misery. Low-dose sermorelin is okay.
Sample stack: Weeks 1-4: Tirz 2.5 mg + BPC 300 mcg daily. Weeks 5-12: Tirz 5-10 mg + TB-500 2 mg twice weekly.
Run each through the calculators. Don't eyeball it.
Storage and handling best practices
Fridge reconstituted tirzepatide at 2 to 8 C. Lasts 28 days max. Freeze dry powder at -20 C for two years.
Traveling? Insulin cooler bag. Under 25 C for 21 days tops.
Limit vial punctures to under 20. Fresh pin every draw.
Go for HPLC >99% purity, endotoxin-free sources. Verify with our tirzepatide calculator.
Multi-dose trick: Pull all your doses into syringes on day one. Fridge them. Good for 14 days.
Advanced protocols: high-dose and custom titration
Over 120 kg? Kick off at 5 mg week one, hit 15 mg by week eight. Data says 15 mg is the ceiling. More doesn't add much.
Athlete custom:
- Week 1: 2.5 mg Mon/Thu (split).
- Weeks 2-4: 5 mg weekly.
- Maintenance: 12.5 mg weekly + 200 mcg MOTS-c twice weekly. MOTS-c calculator.
On a cut? Selank 300 mcg nasal daily weeks 1-8 for headspace. Selank calculator.
Half-life detail: 3% left by day five. Nails the weekly cadence. Forget 5-day pins.
Tracking progress and adjustments
Log injection date, dose, weight, waist measurement, hunger on a 1-10 scale.
Week one: 1-2 kg drop (mostly water). Then 0.5-1 kg per week. Stuck? Bump 2.5 mg or add AOD-9604.
No luck at 10 mg? Microdose HGH 1-2 IU mornings. HGH calculator.
To exit: Taper from 10 mg to 7.5 to 5 to 2.5 over four weeks at week 24. Follow with DSIP 100 mcg nightly for sleep. DSIP calculator.
