Moles and molecules in the vial, and how it compares with the other packs

Published 26 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Dividing 40 mg by 2,174 daltons gives about 18.4 micromoles, or roughly 1.1 times ten to the nineteenth molecules, before correcting for counterion and water. By comparison the GHK-Cu pack at 50 mg is about 123 micromoles because the tripeptide is so light; the Retatrutide pack at 20 mg is about 4.2 micromoles; the IGF-1 LR3 pack at 1 mg is about 0.11 micromoles. MOTS-c sits in the middle: a mid-sized peptide supplied in a relatively large mass.

The arithmetic

Amount in moles is mass divided by molar mass. For a 2,174 dalton peptide, 40 mg is 40 divided by 2,174 millimoles, which is 0.0184 millimoles or 18.4 micromoles. Net peptide content on the certificate reduces this by the counterion and water fraction, typically to around 15 micromoles for a trifluoroacetate salt.

Multiplying by the Avogadro constant gives the molecule count.

The comparison

The catalogue packs span three orders of magnitude in molar content because they span two orders in molecular weight and one in mass. A 2 kDa peptide at 40 mg and a 9 kDa protein at 1 mg differ by more than a hundredfold in molecules. The mass on a label is not a measure of how much active molecule is present without the molecular weight beside it.

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

Reading the figure

The 40 mg is gross mass of the lyophilised salt. The certificate states peptide content. Neither is a quantity for use.

MOTS-c 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.
