GLP1-T
GLP1-T is a pre-filled research pen containing a synthetic dual incretin agonist — a single peptide, 4813.5 g/mol, engineered to activate both the GLP-1 receptor and the GIP (glucose-dependent insulinotropic polypeptide) receptor. Dual and triple incretin agonists are among the most active areas of metabolic research. Supplied at 40 mg, ≥99% purity by HPLC/MS, with a batch-specific COA. Research use only — not a drug product.

What is a GLP-1/GIP dual agonist?
GIP and GLP-1 are the two incretin hormones — gut peptides that amplify insulin secretion after a meal. For decades GIP was considered the less useful of the two; that view changed when unimolecular peptides activating both receptors were shown, in animal and then clinical research, to produce effects beyond GLP-1 agonism alone. GLP1-T supplies a dual agonist of this class in a research format. It is the counterpart to the single-receptor GLP1-R.
What are dual incretin agonists studied for in research?
- Food-intake and preference models. Rodent work reported that a dual agonist selectively reduced preference for fat [1].
- Thermogenesis. A 2022 study described a thermogenic-like amino-acid signature in brown adipose tissue [2].
- Proteomics and next-generation agonists. Plasma-proteome profiling of dual agonism [3] and triple GLP-1/GIP/glucagon agonists [4] show where the field is heading; long-acting GIPR-selective agonists are now in clinical study too [5].
Animal, proteomic and clinical-pharmacology findings on the class. The research-grade material sold here is not a drug and is not for human use.
