What is GHK-Cu and what is GLP-3 RTA?
GHK-Cu is classified as Copper-binding tripeptide · dermal & remodeling research; GLP-3 RTA as Synthetic triple-agonist peptide. 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.
GHK-Cu
Copper-binding tripeptide · dermal & remodeling research
GHK-Cu is a copper-binding tripeptide, glycyl-L-histidyl-L-lysine complexed with copper(II), that occurs naturally in human plasma. Verve supplies it as a high-purity research compound for dermal and tissue-remodeling research.
full GHK-Cu profile →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.
full GLP-3 RTA profile →Which research models is each compound studied in?
GHK-Cu sits in skin & glow research and GLP-3 RTA in weight & metabolic research, so their listed models largely do not intersect. The table lists 4 reported research applications for GHK-Cu and 5 for GLP-3 RTA. Rows are per compound, not equivalences.
| GHK-Cu — reported research applications | GLP-3 RTA — reported research applications |
|---|---|
| Dermal and collagen research models | GLP-1, GIP, and glucagon receptor agonism research |
| Extracellular-matrix remodeling research | cAMP and class B GPCR signaling research models |
| Copper-transport peptide research | Comparative single-, dual-, and triple-agonist pharmacology studies |
| Gene-expression research | Metabolic-pathway and nutrient-handling research models |
| — | Peptide half-life, lipidation, and stability research |
