Semax price comparison
Semax is a synthetic peptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10), typically supplied as a lyophilized powder for laboratory use. In research and laboratory contexts it has been studied as a neuromodulatory peptide and is frequently examined alongside Selank in cognition and neuroprotection models. This index tracks research-use-only (RUO) vendor pricing for Semax so researchers can compare cost across suppliers; it is not for human or veterinary use.

▸ Why compare $/mg for Semax?
Per-mg prices for Semax vary widely because vendors differ in synthesis scale, stated purity, fill accuracy, and whether the listing is for the plain heptapeptide or an N-acetylated variant. Comparing normalized $/mg across suppliers helps a researcher spot outliers, identify better value at a given purity grade, and avoid overpaying for equivalent material.
▸ Reading the COA
For Semax, confirm identity by mass spectrometry against the expected monoisotopic mass (roughly 813.9 Da for the free peptide, Met-Glu-His-Phe-Pro-Gly-Pro), since the acetylated N-Semax variant will show a different mass. Check that HPLC purity is stated as 98%+ and that the chromatogram is included rather than just a summary number. Common issues to watch for are truncated or deletion sequences, residual TFA from purification, and unlisted counter-ion or salt content that inflates the apparent net peptide weight.
