What Is Semax? Identity and Research Context

Semax is searched by name far more often than it is explained accurately. This overview keeps to what can be stated plainly and checked against public records: what Semax is as a molecule, and the research field it belongs to. It does not make claims about what it does.

What Semax is

Semax is a synthetic peptide derived from a fragment of ACTH, the ACTH 4-7 sequence extended with Pro-Gly-Pro. Its identity is publicly checkable: PubChem CID 9811102, CAS 80714-61-0, molecular formula C37H51N9O10S, and an average molecular weight of about 814 g/mol.

What research areas is Semax associated with?

Because Semax is an ACTH-fragment peptide, in the scientific literature it is discussed within neuropeptide research and the study of ACTH-derived peptides, part of the broader field of peptide neurochemistry. That names the research area the molecule sits in; it is not a statement about any effect, result, dose, or use. Naming a field of study is not the same as making a claim.

Why we describe it this way

Most pages selling a compound like this lead with what it supposedly does. We do not: these products are sold strictly for laboratory research, so outcome and use claims are not appropriate, and what actually separates suppliers is whether the material is what the label says. That is a documentation question, and we answer it in public with a third-party certificate for every lot.

Check the lot yourself

Look up any lot on our public register, read our guide on how to read a COA, or see what >98% purity actually means across every lot we publish. Browse the product itself: Semax. More identity guides: Selank and Tesamorelin.
