Same labeled amount, different peptide
Both listings are 50 mg copper peptides. GHK-Cu is studied in copper-peptide coordination, fibroblast gene-expression, and extracellular-matrix models. AHK-Cu is studied in copper-peptide coordination and fibroblast and matrix assays under its own sequence. The shared copper does not make GHK and AHK the same tripeptide.
If a paper says GHK, do not file it under AHK. The sequences are short, and the letters are the identity.
The COAs split the copper question differently
GHK-Cu task 165759, analysis May 20, 2026, prints GHK 44.74 mg, copper 1.87 mg, and purity 99.453%. AHK-Cu task 105237, batch 5/2026, analysis February 3, 2026, prints AHK-CU 55.25 mg and purity 99.89%. The GHK report separates the peptide mass and the copper mass. The AHK report prints one measured value for the complex.
Do not average those numbers or treat 55.25 mg as the contents of a GHK vial.
