Structural class
GLP-3R is a 36-amino acid GLP-1R/GIPR/GcgR triple agonist representing the first published peptide with balanced full agonism across all three incretin/glucagon-axis receptors.
Pathways studied
GLP-3R activates GLP-1R and GIPR via the same Gs-cAMP-PKA cascade as GLP-2 TZ, while also engaging the glucagon receptor (GcgR), which adds pathway outputs relevant to hepatic glucose production and fatty acid oxidation assay models. Achieving balanced potency across three structurally similar class B GPCRs simultaneously required extensive sequence engineering — studies examining its binding mode at each receptor provide a useful platform for understanding receptor-selectivity determinants within the incretin peptide family.
Typical research focus
The key research design challenge is separating the individual receptor contributions in cell systems that co-express some or all three targets. Selective antagonists or receptor-knockout models used alongside GLP-3R enable attribution of specific readouts to each pathway, making comparator design more demanding but more informative than single-pathway assays.

How to read a certificate of analysis, what purity actually measures, and how research peptides are stored and independently verified.
The questions researchers ask most.
Janoshik Analytical reports are published for 12 products, and each one links straight to the lab's own record, so you can check the result yourself before you buy — nothing to take on trust. More are listed as pending on the COA page.
Keep vials sealed, dry, and out of direct light. Lyophilised (freeze-dried) peptides are stable at -20 °C; once reconstituted, store as noted on the product label. Full handling notes sit on every product page.
Order by 2pm for same-day dispatch from our Melbourne warehouse, otherwise the next business day, with tracked delivery Australia-wide. No customs, no border delays — it's already in the country.

Researchers who bought GLP-3R also stock these.
It brings together 5 labelled variants: 10mg, 15mg, 30mg, 40mg, and 20mg, current pricing context, stock visibility, COA access, and internal links to related catalogue pages so a laboratory buyer can review the material from a single reference URL.
GLP-3R is generally discussed as a 36-amino acid GLP-1R/GIPR/GcgR triple agonist representing the first published peptide with balanced full agonism across all three incretin/glucagon-axis receptors. The most relevant background is sequence behaviour, pathway or receptor context where documented, and analytical consistency under controlled laboratory conditions.
Use the label, COA, and internal SOPs as the primary guide. In general, store the material under controlled laboratory conditions, minimise avoidable environmental exposure, and keep variant tracking records current.
Yes. This listing includes access to a product-specific COA, which should be reviewed before use so purity, identity, and documentation checks are aligned with the project record.
No. The page should be interpreted strictly in a research and laboratory context. It does not provide dosage guidance, treatment claims, or human or animal use instructions.
