What the two have in common, and where they differ
N-acetyl Semax is Semax with an acetyl group at the N-terminus. N-terminal acetylation often protects peptides from breakdown by aminopeptidases. The sequence is otherwise the same.
How to read this comparison
The table shows only data that are documented for the substance or set by the catalogue. A dash means no verified value is on file. Substance data come from PubChem where the record is unambiguous.
The price per mg is the catalogue price of the size that is cheapest per mg, divided by the declared amount on the label. It does not allow for peptide content, which is the share of peptide in the weighed material. How the two differ is explained in the article on peptide content and purity.
An earlier analysis describes a sample tested in 2021 or 2022. It is not a certificate of analysis for the lot delivered today. The certificate of the current lot is on the product page once a lot is released.
