Our read Opinion
No blend trials were found. A 52-person fMRI study tested Semax or Selank separately, not the combination; separate-component results do not establish meaningful cognitive benefit from the blend.

Semax is an ACTH-fragment analog with proposed neurotrophic effects; Selank is a tuftsin analog with proposed anxiolytic signaling effects. Their combined mechanism and clinical synergy are unestablished.
Not a peptide: a pre-mixed blend of Semax + Selank. No FDA approval was identified for either component or the blend. Reports of component approvals outside the US do not establish approval of this combination; blend authorization elsewhere is unverified.
