Fifty, ten and ten milligrams is not fifty, ten and ten molecules

By mass the blend is about 71 per cent GHK-Cu and 14 per cent each of TB-500 and BPC-157. Because GHK-Cu is a tripeptide of about 340 daltons while TB-500 is about 1880 and BPC-157 about 1419, GHK-Cu accounts for roughly nine of every ten molecules in the vial. The label describes mass; the chemistry is governed by molecules.

The arithmetic

Dividing each mass by its molecular weight gives the number of moles. Fifty milligrams of a 340-dalton peptide is many more molecules than ten milligrams of an 1880-dalton one — about twenty-eight times as many, before the copper is counted. On the same basis BPC-157 at 1419 daltons contributes a little more than TB-500 by molecule for the same mass.

The result is a vial that is dominated numerically by the copper tripeptide, with the two larger peptides present as minor species by count.

Why the distinction matters

Receptor engagement, binding and most chemistry scale with molecules, not grams. A reader who pictures the blend as mostly GHK-Cu by mass has it right; one who pictures three comparable components has it wrong by an order of magnitude for the two peptides.

This is also why a 70 mg blend and three single vials totalling 70 mg are not interchangeable descriptions unless the masses per component match.

What the label can and cannot say

The carton states masses because that is what is weighed into the vial. The molar composition follows from those masses and the molecular weights recorded in the catalogue, and is stated here so that the two descriptions are not confused.

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