NA Semax

NA Semax is a chemically stabilized version of Semax, a short synthetic peptide based on a fragment of the ACTH hormone. The "NA" comes from a small acetyl tweak on one end of the chain, which gives it a different stability profile than the original. It is best known in cognitive and neuropeptide research, and its tweaked structure is what sets it apart from standard Semax.

It also sits on a solid research base, including work on how peptides like this bind metals and behave in the body (Magrì et al., 2016, Journal of Inorganic Biochemistry). That makes it a useful reference compound for this kind of study.
