what each one is
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.

What is GHK-Cu?
GHK-Cu is a naturally-occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine). Verve supplies it as a research compound for laboratory use only, not for human or veterinary use.
What is GHK-Cu studied for in research?
It is used as a model compound in dermal, collagen, extracellular-matrix remodeling, and gene-expression research. Verve makes no health claims.
What is GLP-3 RTA?
GLP-3 RTA is a synthetic peptide that acts as an agonist at three receptors — GLP-1, GIP, and glucagon. Verve supplies it as a research compound for laboratory use only, not for human or veterinary use.
What is GLP-3 RTA studied for in research?
In in-vitro and pre-clinical models it is used as a reference agonist in incretin-receptor pharmacology, cAMP signaling, and metabolic-pathway research. Verve makes no claims about use in humans or animals.
