Semax vs Selank
Two cognitive peptides compared by a board-certified neurologist - the difference matters.
Medically reviewed by Charles Kamen, MD, board-certified neurologist ·
Semax and Selank are both studied in brain and nervous-system contexts, but the research questions differ. A medical evaluation with Dr. Charles Kamen, MD, a board-certified neurologist, can help put those differences in context.
This is an educational comparison. Whether either is appropriate for you is determined after a medical evaluation.
| Semax | Selank | |
|---|---|---|
| Primary research focus | Cognition, focus, neuroprotection | Calm focus, stress resilience, mood |
| Origin | Derived from an ACTH fragment | Based on the peptide tuftsin |
| Often considered for | Mental clarity and attention | Stress and a sense of calm focus |
| FDA status | Not FDA-approved | Not FDA-approved |
| Supervision | Neurologist-led, evaluation-first | Neurologist-led, evaluation-first |
The practical answer: Semax is studied more for focus and neuroprotection; Selank more for calm and stress resilience. Some protocols consider them in different contexts. Both are evaluated and supervised by a board-certified neurologist - a real advantage for nervous-system peptides.
