The smallest molecule in the catalogue in the largest number of molecules, and what that comparison teaches

Published 26 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
GHK-Cu has a molecular mass of about 403 daltons as the copper complex — the tripeptide at about 340 plus copper less two protons. Fifty milligrams is therefore about 124 micromoles, or roughly 7.5 times ten to the nineteenth molecules, before correcting for counterion and water. One copper per complex gives about 7.9 mg of copper in the vial, about 16 per cent of the gross mass. By comparison the Retatrutide pack at 20 mg holds about 4.2 micromoles and the IGF-1 LR3 pack at 1 mg about 0.11, so the smallest molecule in the catalogue comes in by far the largest count.

The arithmetic

Moles equal mass over molar mass: 50 over 403 milligrams per millimole is 0.124 millimoles. Net peptide content on the certificate, accounting for water and the counterion on the lysine, reduces this somewhat. Copper mass is moles times 63.5, the atomic mass of copper. The GLOW pack, with 50 mg GHK-Cu among its three components, carries the same copper.

The certificate copper-content line is the measured counterpart of this calculation.

The comparison

Across the catalogue, molar content spans three orders of magnitude for masses that span less than two, because molecular weight spans from 403 to 22,000. A tripeptide at 50 mg and a protein at 1 mg differ by a thousandfold in molecules. Any comparison between products in mass alone is a comparison of weights, not of molecules.

This is a statement about reading labels and not a quantity for any use.

Reading the figure

The 50 mg is gross mass of the lyophilised complex as its salt. The certificate states peptide content and copper content. Neither is a quantity for use.
