Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

N-Acetyl Semax amidate is a chemically modified version of Semax, a synthetic peptide based on a fragment of adrenocorticotropic hormone (ACTH 4-10). The added acetyl and amide groups are intended to make the molecule more stable and longer lasting than Semax itself. It is thought to act on brain signaling pathways similar to Semax, such as influencing neurotrophic factors like BDNF, but this has not been shown for the modified form.

What the evidence shows

Automatic summaryAnecdotal

There are no registered human trials and no published papers found on this specific modified form, so claims about its effects rest on community reports and extrapolation from research on the parent compound Semax. It is not FDA-approved, and its effects and safety in humans are unknown.
