Compound comparison
MOTS-c vs GHK-Cu
As of 2026-09-08, DMV Research compares MOTS-c (CAS 1456083-98-9) and GHK-Cu (CAS 89030-95-5) across 13 identity and analytical axes, backed by 2 published third-party certificates of analysis, for laboratory research use only.
This page sets two research compounds beside each other on the facts DMV Research can evidence: registry identity, the assay each lot was tested by, and what the catalog currently lists. It states what each compound IS, not what it does, and it does not put one ahead of the other — both are supplied for laboratory research use only.

MOTS-c and GHK-Cu, side by side
Every row is read from a published record — the compound guides for identity, the per-lot certificates for the analytical results, and the live catalog for price. A dash means the fact is not published for that compound, not that it is zero.

Frequently asked questions
What is the structural difference between MOTS-c and GHK-Cu?
They are different classes of molecule with separate CAS registrations: MOTS-c is a 16-amino-acid mitochondrial-derived peptide (CAS 1456083-98-9), and GHK-Cu is a copper(II)-coordinated tripeptide complex (CAS 89030-95-5).
Do MOTS-c and GHK-Cu share a CAS number?
No. MOTS-c is CAS 1456083-98-9 and GHK-Cu is CAS 89030-95-5. A CAS registry number identifies one substance, so two different numbers are two different substances.
How is each compound analysed before it is listed?
Both are assayed by third-party laboratory testing for identity and purity, and the resulting per-batch certificate is published on this site.
Are MOTS-c and GHK-Cu both listed as standalone products at DMV Research?
Yes. Both are listed individually in the catalog, each with its own per-batch Certificate of Analysis.
Does this page say which compound to pick?
No. It compares registry identity, analytical results and catalog availability only. Both compounds are supplied for laboratory research use only, and this site publishes no guidance on use, effect, or suitability for any application.
