What is GHK-Cu and what is TB-500?
GHK-Cu is classified as Copper-binding tripeptide · dermal & remodeling research; TB-500 as Thymosin β4 fragment · tissue-repair 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.
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.

Thymosin β4 fragment · tissue-repair research
TB-500 is a synthetic 43-amino-acid peptide corresponding to an active fragment of thymosin beta-4, a naturally-occurring actin-binding protein. Verve supplies it as a high-purity research compound for tissue-repair and cellular research.
full TB-500 profile →Which research models is each compound studied in?
GHK-Cu sits in skin & glow research and TB-500 in recovery & gut research, so their listed models largely do not intersect. The table lists 4 reported research applications for GHK-Cu and 4 for TB-500. Rows are per compound, not equivalences.
| GHK-Cu — reported research applications | TB-500 — reported research applications |
|---|---|
| Dermal and collagen research models | Cell-migration research models |
| Extracellular-matrix remodeling research | Actin-regulation and cytoskeletal research |
| Copper-transport peptide research | Angiogenesis research |
| Gene-expression research | Tissue-repair research models |
Research contexts only. Both compounds are supplied for laboratory research use only, and no entry above describes an effect in humans or animals.
Does verve co-formulate GHK-Cu and TB-500 together?
Yes. Both compounds appear together in 2 verve blends, so researchers who study GHK-Cu and TB-500 in the same model can work from a single co-formulated vial rather than two separate preparations:
