What is GLP-3 RTA and what is Selank?
GLP-3 RTA is classified as Synthetic triple-agonist peptide; Selank as Synthetic heptapeptide. 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.

Synthetic heptapeptide
Selank is a synthetic heptapeptide, a seven-amino-acid chain built from the endogenous immunomodulatory tetrapeptide tuftsin with a C-terminal Pro-Gly-Pro extension added to increase stability. Verve supplies it as a high-purity research compound for neuroscience and peptide-signaling research.
full Selank profile →Which research models is each compound studied in?
GLP-3 RTA sits in weight & metabolic research and Selank in mind & sleep research, so their listed models largely do not intersect. The table lists 5 reported research applications for GLP-3 RTA and 5 for Selank. Rows are per compound, not equivalences.
| GLP-3 RTA — reported research applications | Selank — reported research applications |
|---|---|
| GLP-1, GIP, and glucagon receptor agonism research | Regulatory-neuropeptide signaling research |
| cAMP and class B GPCR signaling research models | GABAergic and monoaminergic pathway research models |
| Comparative single-, dual-, and triple-agonist pharmacology studies | Neurotrophic gene-expression studies |
| Metabolic-pathway and nutrient-handling research models | Tuftsin-analog structure–activity research |
| Peptide half-life, lipidation, and stability research | Peptide-stability and degradation-kinetics research |
