Are selank and semax the same thing?

No, they are different molecules developed by the same Russian research tradition and often discussed together because both are intranasal peptides with short half lives and no FDA approval. Semax is derived from ACTH and researched mainly for cognition, focus, and stroke recovery. Selank is derived from tuftsin and researched mainly for anxiety and stress resilience. They are sometimes used together, but no trial has tested that specific combination.
