Tirzepatide is a synthetic 39 amino acid dual GLP-1/GIP receptor agonist, engaging both incretin receptor systems in a single molecule. This chart is the reconstitution reference for Irish research groups using Tirzepatide in preclinical protocols.
Tirzepatide fundamentals
- Class: Dual GLP-1R + GIPR agonist
- Amino acids: 39
- Molecular weight: ≈ 4813.5 Da
- Standard presentation: 10 mg per vial
- Storage: Lyophilised −20 °C; reconstituted 2–8 °C
Reconstitution reference and 10 mg Tirzepatide vial
| Bacteriostatic water | Working concentration | Volume for common doses |
|---|---|---|
| 1.0 ml | 10 mg/ml | 500 µg → 50 µl · 1 mg → 100 µl · 2.5 mg → 250 µl |
| 2.0 ml | 5 mg/ml | 500 µg → 100 µl · 1 mg → 200 µl · 2.5 mg → 500 µl |
| 4.0 ml | 2.5 mg/ml | 500 µg → 200 µl · 1 mg → 400 µl |
Reconstituted stability
Tirzepatide reconstituted in bacteriostatic water is stable at 2–8 °C for approximately 4 weeks. Aliquot and freeze for extended-protocol use.
Regulatory context : Ireland
Tirzepatide is a current HPRA enforcement focus. Supplied strictly for in-vitro laboratory research see our HPRA guide.
Comparison with Semaglutide and Retatrutide
- Semaglutide (mono) and GLP-1R only
- Tirzepatide (dual) : GLP-1R + GIPR
- Retatrutide (triple) — GLP-1R + GIPR + GCGR
