GLP-2/Tirz is our name for tirzepatide, a lab-made peptide that acts on two receptors at once (GLP-1 and GIP), which is why it’s called a “dual agonist.” It’s one of the most important compounds in metabolic research. This is the research compound, not a prescription medicine. It comes as a freeze-dried powder in a 10 mg vial.

GLP-2/Tirz — compound background
Lipidated dual receptor agonist (GIP / GLP-1), 39-residue chain
GLP-2/Tirz is built on a GIP-based backbone rather than a GLP-1 one — an important and often-missed design detail. It was engineered from the GIP sequence and modified to acquire GLP-1 receptor activity, with a C20 fatty diacid attached via a linker for albumin binding. The term "twincretin" describes the dual incretin activity.
Solubility & reconstitution
Dissolves well but shares the amphiphilic behaviour of all lipidated peptides — prone to foaming, self-associating at higher concentrations. Allow several minutes of gentle swirling rather than forcing dissolution.
Commonly worked at 5–10 mg/mL.
Storage
Sealed at -20 °C. Robust as dry powder. Refrigerate at 2–8 °C. The albumin-binding modification confers good solution stability.
Commonly worked with for 4–6 weeks at 2–8 °C.
Stability
Do not freeze reconstituted solution. Interfacial aggregation during freezing is the characteristic failure mode and is irreversible.
Reading the Certificate of Analysis
Confirm the mass near 4813.5 Da. As with GLP-3/RT, aggregate content is the check that RP-HPLC purity alone will not give you. For a 39-residue synthesis, also review the chromatogram for closely eluting deletion sequences.
