How much of fifty milligrams is actually GHK-Cu

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
The mass in a vial is the sum of the peptide complex, its counterion and residual water. Net peptide content, typically expressed as a percentage, is the complex alone. For a lyophilised peptide salt it commonly falls somewhere between 70 and 90 per cent of gross mass, depending on counterion and moisture. The certificate figure for the lot is the only way to know it for a given vial.

The three contributors

The complex itself, with a defined molecular weight. The counterion — trifluoroacetate is heavier than acetate — paired to each positive charge. Water, absorbed into the cake and controlled at release. Gross mass is all three; peptide content removes the second and third.

For a small peptide with a charged residue, counterion and water can be a substantial share.

How it is derived

Water content by Karl Fischer titration, counterion content by ion chromatography or inferred from stoichiometry, and sometimes amino acid analysis or nitrogen determination to measure the peptide directly. The certificate reports the result for the lot.

Two 50 mg vials from different sources can contain different amounts of compound.

Why it matters

Any calculation of molar quantity from mass is wrong by the difference unless peptide content is applied. The copper content figure and the peptide content figure together describe what the vial actually holds. Both are part of GHK-Cu lot documentation, available on request.
