What is GLP-3 RTA and what is KPV?
GLP-3 RTA is classified as Synthetic triple-agonist peptide; KPV as Tripeptide alpha-MSH fragment. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
GLP-3 RTA
Synthetic triple-agonist peptide
GLP-3 RTA is a synthetic single-chain peptide engineered to act at three related class B G-protein-coupled receptors at once: the GLP-1 receptor, the GIP receptor, and the glucagon receptor. Its backbone is derived from the incretin peptide family and carries a fatty-acid modification that extends plasma half-life in pre-clinical systems, making it a widely cited reference agonist in incretin-receptor research.

Tripeptide alpha-MSH fragment
KPV is a tripeptide composed of lysine, valine, and proline, corresponding to the C-terminal fragment (residues 11–13) of alpha-melanocyte-stimulating hormone (alpha-MSH). It is the smallest sequence retained from that parent peptide and is widely used as a compact reference compound in cellular signaling research, where its short chain length makes it convenient for controlled in-vitro work.
full KPV profile →Which research models is each compound studied in?
GLP-3 RTA sits in weight & metabolic research and KPV in recovery & gut research, so their listed models largely do not intersect. The table lists 5 reported research applications for GLP-3 RTA and 5 for KPV. Rows are per compound, not equivalences.
| GLP-3 RTA — reported research applications | KPV — reported research applications |
|---|---|
| GLP-1, GIP, and glucagon receptor agonism research | Inflammatory-signaling research models (NF-κB pathway studies) |
| cAMP and class B GPCR signaling research models | Cytokine-expression research in cultured cells |
| Comparative single-, dual-, and triple-agonist pharmacology studies | Melanocortin-receptor and alpha-MSH fragment research |
| Metabolic-pathway and nutrient-handling research models | Epithelial and mucosal-barrier research models |
| Peptide half-life, lipidation, and stability research | Structure–activity studies of short peptide fragments |
