Tiers name what a vendor publishes, not a verdict on any product's purity or quality. Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do). Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site. Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score. Affiliate relationships never affect tiers, selection or order. How the Vendor Score works
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.
Evidence brief
Semax is a synthetic heptapeptide analogue of the ACTH(4-10) fragment, studied mainly in animal and cell models as a nootropic and neuroprotective agent, with a small human literature.

Semax is a synthetic heptapeptide analogue of the ACTH(4-10) fragment, studied mainly in animal and cell models as a nootropic and neuroprotective agent, with a small human literature.

Corticotrophin (ACTH) and its analogues, particularly Semax (Met-Glu-His-Phe-Pro-Gly-Pro), demonstrate nootropic activity. Close functional and anatomical links have been established between melanocortinergic and monoaminergic brain…
Consisting of a fragment of ACTH(4-7) and C-terminal PGP tripeptide, the polypeptide Semax is successfully used for acute stroke therapy. Previous experiments showed rapid induction of Bdnf, Ngf, and TrkB expression in intact rat…
Lysosomal membrane permeabilization (LMP) is exacerbated following spinal cord injury (SCI), leading to increased neuronal cell death. Ubiquitination may affect LMP by regulating the stability and functionality of lysosomal membranes.…

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.
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.
