What is GLP-3 RTA and what is Tesamorelin?
GLP-3 RTA is classified as Synthetic triple-agonist peptide; Tesamorelin as Synthetic GHRH analog · secretagogue 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 GHRH analog · secretagogue research
Tesamorelin is a synthetic 44-amino-acid peptide, a stabilized analog of growth-hormone-releasing hormone (GHRH). Verve supplies it as a high-purity research compound for endocrine and secretagogue research.
