The vial in micromoles and molecules, and how it compares with the other packs in the catalogue

Published 26 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Dividing 20 mg by 5,136 daltons gives about 3.9 micromoles, or roughly 2.3 times ten to the eighteenth molecules, before correction for counterion and water. The Retatrutide pack, also 20 mg but at about 4,731 daltons, holds about 4.2 micromoles; the somatropin pack at 24 mg and 22,124 daltons about 1.1 micromoles; the MOTS-c pack at 40 mg and 2,174 daltons about 18 micromoles; the GHK-Cu pack at 50 mg about 123 micromoles. Two packs of equal mass can differ severalfold in molecules, and the molecular weight is what connects them.

The arithmetic

Moles equal mass over molar mass: 20 milligrams over 5,136 grams per mole is 0.0039 millimoles. Net peptide content on the certificate reduces this by the counterion and water fraction, typically to around 3.3 to 3.5 micromoles. Multiplying by the Avogadro constant gives the molecule count. The hexenoyl group is part of the molar mass.

The same arithmetic page exists for several products on this site so that comparisons can be made.

The comparison

Tesamorelin and Retatrutide are of similar size and supplied at the same mass, so their molar contents are close, which is a coincidence of the price list rather than a design. Somatropin, four times heavier, holds a quarter as many molecules per milligram. The tripeptide GHK-Cu holds thirty times as many. Receptor pharmacology is molar, so these differences matter for any comparison across products.

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

Reading the figure

The 20 mg is gross mass of the lyophilised acetate salt. The certificate states peptide content. Neither is a quantity for use.

Tesamorelin is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
