What is GLP-3 RTA and what is Semax?
GLP-3 RTA is classified as Synthetic triple-agonist peptide; Semax as Synthetic heptapeptide · neuro research. 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 · neuro research
Semax is a synthetic heptapeptide, a seven-amino-acid chain based on a fragment of adrenocorticotropic hormone, ACTH(4–10), with a C-terminal Pro-Gly-Pro extension added for stability. Verve supplies it as a high-purity research compound for neuroscience research.
full Semax profile →Which research models is each compound studied in?
GLP-3 RTA sits in weight & metabolic research and Semax in mind & sleep research, so their listed models largely do not intersect. The table lists 5 reported research applications for GLP-3 RTA and 4 for Semax. Rows are per compound, not equivalences.
| GLP-3 RTA — reported research applications | Semax — reported research applications |
|---|---|
| GLP-1, GIP, and glucagon receptor agonism research | Neurotrophic-signaling (BDNF) research |
| cAMP and class B GPCR signaling research models | Neuroprotection research models |
| Comparative single-, dual-, and triple-agonist pharmacology studies | Cognitive-research models |
| Metabolic-pathway and nutrient-handling research models | Peptide-stability research |
