Tirzepatide
How it works
Tirzepatide activates both GLP-1 and GIP receptors — the dual mechanism produces stronger appetite suppression and greater weight loss than semaglutide in head-to-head trials. Weekly subcutaneous injection.
Typical titration schedule
- Weeks 1–4: 2.5mg/week (starter)
- Weeks 5–8: 5mg/week
- Maintenance options: 10mg or 15mg/week
Price range
Brand Zepbound: ~$1,060–1,300/month (savings card may apply). Compounded tirzepatide: $150–450/month.
Key considerations
SURMOUNT trials showed ~20–22% avg. weight loss at 72 weeks. Strongest efficacy data of any GLP-1 class medication currently. Similar side effect profile to semaglutide. Supply normalising after the 2024–2025 shortage.
