PEPTIDES4ALL Cagrilintide + Retatrutide is a research peptide combination intended for laboratory studies involving multi-receptor pharmacology and multi-pathway signaling. This formulation pairs:

• Cagrilintide, commonly evaluated in research models of amylin/calcitonin receptor biology (AMY receptor systems and related calcitonin-family receptor complexes), and

• Retatrutide (LY-3437943), commonly evaluated as a multi-receptor agonist across GLP-1R, GIPR, and GCGR experimental systems.

Used together in controlled research settings, this combination can support investigation of:

• Receptor profiling and functional assays across amylin/calcitonin-family and incretin/glucagon receptor models

• Cell-based signaling characterization, including second-messenger readouts and pathway mapping under defined assay conditions

• Comparative and combination-study design, such as evaluating single-agent versus dual-agent signaling patterns in standardized workflows

• Mechanistic exploration of multi-ligand receptor engagement, kinetics, and signaling behavior in complex experimental designs

• Peptide engineering / translational modeling, where multi-target pathway engagement is being studied at the receptor and signaling level

This product is supplied as a lyophilized research peptide combination for controlled laboratory use.

Key Research Features (Non-therapeutic)

• Multi-axis research utility: compatible with experimental models spanning amylin/calcitonin-family receptors and GLP-1R/GIPR/GCGR systems

• Useful for ligand panel workflows: supports side-by-side comparison of mono- vs combination conditions in receptor assay development

• Designed for mechanistic studies: applicable to investigations of receptor engagement patterns and pathway readouts in vitro (per protocol)
