Tirzepatide in the UK: research-grade supply explained
Tirzepatide is the most studied dual-incretin compound in metabolic research. This page explains how research-grade tirzepatide supply works in the UK, how it differs from prescription Mounjaro, and what to check before choosing a source. For laboratory research use only.
Dual GIP + GLP-1 agonist
The reference dual-incretin compound in metabolic research, studied across glycaemic-control and weight-management models.
Third-party tested
Every batch independently verified for identity and purity by an external laboratory, with certificates of analysis on request.
Next-day UK delivery
Same-day dispatch before cut-off, tracked next-day delivery in temperature-controlled packaging.
Research supply vs prescription supply
Tirzepatide exists in two entirely separate UK supply chains. The licensed medicine (Mounjaro) is prescribed by clinicians and dispensed by pharmacies under MHRA regulation. Research-grade tirzepatide is the same peptide molecule supplied as a research chemical for laboratory work — it carries no medical licence, cannot be sold for consumption, and its quality rests entirely on the supplier’s manufacturing and testing standards.
That last point is the practical one: with no regulator checking each batch, third-party testing of the finished product is the only meaningful quality signal in the research market. RegenMed publishes testing for every batch and makes certificates of analysis available on request.
| Compound | Receptor targets | Development status |
|---|---|---|
| Semaglutide | GLP-1 | Licensed (Wegovy, Ozempic) |
| Tirzepatide | GLP-1 + GIP | Licensed (Mounjaro, Zepbound) |
| Retatrutide | GLP-1 + GIP + glucagon | Phase 3 trials — not yet licensed |
