GLP-1 Research Peptides

GenoPept’s GLP-1 research range brings together the incretin-mimetic peptides most widely studied in metabolic and body-composition research — GLP-1, GIP and glucagon receptor agonists including Semaglutide, Tirzepatide, Retatrutide, Cagrilintide, Mazdutide, Liraglutide and Survodutide, alongside research combinations such as CagriSema and Reta-Cagri.

These compounds are investigated in laboratory models for their roles in glucose regulation, appetite signalling and energy balance. Every peptide is supplied research-grade, independently HPLC- and MS-verified to ≥99% purity, and ships with a batch-specific Certificate of Analysis (COA). Selected lines are available as lyophilised vials or pre-filled research pens.

Frequently asked questions

What are GLP-1 research peptides?
GLP-1 research peptides are incretin-mimetic compounds — GLP-1, GIP and glucagon receptor agonists such as Semaglutide, Tirzepatide and Retatrutide — studied in metabolic, glucose-regulation and appetite-signalling research. They are supplied for laboratory research use only.
What is the difference between single, dual and triple agonists?
Semaglutide activates the GLP-1 receptor only; Tirzepatide is a dual GLP-1 and GIP agonist; Retatrutide is a triple GLP-1, GIP and glucagon agonist. See our Semaglutide vs Tirzepatide vs Retatrutide comparison.
Are your GLP-1 research peptides tested?
Yes. Every batch is independently HPLC- and MS-verified to at least 99% purity and ships with a batch Certificate of Analysis (COA).
How are they supplied?
As lyophilised research vials and, for selected lines, pre-filled research pens, dispatched discreetly from the UK.
