What the 10 mg gross mass contains besides peptide, and how net content is stated for two components

Published 26 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
The label mass of 10 mg is the weight of the lyophilised salt mixture. Residual water is measured once for the cake by Karl Fischer titration and applies to the whole. Counterion content is measured as total trifluoroacetate or acetate and, if apportioned, follows the basic sites of each peptide — the lysine-rich fragment carries most, BPC-157 with its two basic sites carries little. Net peptide content is then stated either for the cake as a whole or per component, using the chromatographic ratio of the two to divide it. A certificate that states one number for a two-component product should say which it is.

Water

Karl Fischer titration on a weighed sample of the cake gives per cent water by mass, typically a few per cent for a lyophilised peptide. It is a release measurement; the cake takes up moisture after opening. The figure is subtracted from gross mass along with counterion to give peptide mass.

The GHK-Cu pages describe the method.

Counterions

Measured by ion chromatography or fluorine NMR as total counterion. Apportioning between the components is a calculation from their charge counts; it matters because the same total counterion mass is a larger fraction of the fragment than of BPC-157. Net content per component is gross mass times the chromatographic fraction of that component, less its share of water and counterion.

A 1:1 mass ratio of salts is not a 1:1 ratio of peptide once counterions differ, which the certificate figures show.

Why it is here

Because the gross mass on the label is not the peptide mass, and for a blend the gap is apportioned. It describes analytics and no use of the pack.

The BPC-157 + TB500 blend is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for each component of the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
