Every residue in the sequence contributes a known mass, as do the fatty-acid chain, its linker and any modified residues. Summing them gives the expected molecular weight. The catalogue states this figure for the Retatrutide Pack because it is the value a batch is checked against.
Average and monoisotopic masses differ slightly, and a certificate should say which it reports. For a peptide of this size the difference is small but real.
The instrument ionises the sample and measures mass-to-charge ratio. Peptides typically carry several charges, so the spectrum shows a series of peaks from which the neutral mass is calculated. Agreement with the expected mass to within instrument tolerance is the identity confirmation.
A spectrum showing additional masses indicates related species — truncations, oxidation products, or a different compound — and is informative in a way a single purity number is not.
The side chain adds a defined mass. A batch with the right peptide and the wrong side chain, or no side chain, would have a different pharmacology and a different mass. Mass spectrometry distinguishes them; chromatography alone might not.
Lot-specific identity data for material supplied by REVIVE LAB UAE is available on request.
Retatrutide is supplied by REVIVE LAB UAE as an investigational research material for laboratory use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not approved for any use anywhere, and no dosing, administration or protocol guidance is provided.
