Semax vs. Selank

Two synthetic neuropeptides with different source motifs and overlapping but non-equivalent cognition and stress-response research contexts.

ACTH-fragment-derived neuropeptide

Semax

Investigated across neurotrophic, transcriptional, and stress-response signaling; no single mechanism explains the full literature.

Evidence score2/5

Early human evidence

The score summarizes evidence maturity, not safety, effectiveness, or suitability for any use.
