Potential Benefits of Semax / Selank
Focus & Cognitive Clarity (Semax)
Commonly used in clinics to support attention, working memory, and task switching without typical stimulant jitter.
Calm & Stress Modulation (Selank)
Reported to promote a settled, non-sedating calm for daytime use; often paired with breathwork/sleep hygiene.
Daytime-Friendly, Non-Hormonal
Intranasal peptides with quick onset, designed to complement coaching on lifestyle, sleep, and nutrition.
Important: Semax and Selank are investigational in the U.S. and not FDA-approved for any indication. Use only under the supervision of a licensed clinician. This content is educational and not medical advice.
Contraindications & Precautions
Contraindications
-
Known hypersensitivity to Semax/Selank or formulation excipients
-
Pregnancy or breastfeeding (insufficient safety data)
-
Active nasal/sinus infection or recent nasal surgery without clinician clearance
Use with Caution
-
Seizure disorders, bipolar spectrum, or uncontrolled anxiety—specialist oversight
-
Hypertension sensitive to stimulants (monitor BP/HR at start)
-
Frequent nosebleeds, severe allergic rhinitis, or significant septal deviation
-
Concurrent psychoactive meds (e.g., MAO inhibitors, sedatives)—coordinate with prescriber
-
Using other intranasal agents (decongestants, steroids): separate dosing windows
Outcomes, Dosing & Side Effects
What Patients Commonly Report
-
Semax: Crisper focus, mental stamina, easier “task switching”
-
Selank: Calmer baseline, fewer stress spikes, steadier mood
-
Onset typically 15–60 minutes; duration a few hours (varies by individual)
-
Best outcomes with sleep, hydration, protein-forward nutrition, and stress skills
Dosing & Administration (Clinic-Directed)
-
Route: Intranasal spray/drops per clinic protocol
-
Frequency: Often 1–3× daily or as-needed on work/study days; cycles may be used
-
Technique: Prime device → chin slightly tucked → aim laterally → gentle sniff; avoid forceful inhalation
-
Spacing: If using both, separate by 5–10 minutes; avoid blowing nose for ~10–15 minutes after
-
Storage: Follow label; many preparations prefer refrigeration and protection from light
Exact concentration and schedule are individualized by your licensed provider.
Side Effects — Common
-
Nasal irritation/dryness, drip taste, mild headache
-
Transient drowsiness (more with Selank) or alertness (more with Semax)

Patient Story:
“Semax helped me lock in for deep work; Selank kept me steady during stressful meetings. Using both with better sleep hygiene made the effect feel natural.” — Maya T.
Mechanism of Action (Proposed)
-
Semax: Analog of ACTH(4–10); linked in studies to neurotrophic signaling (e.g., BDNF pathways) and attention networks
-
Selank: Analog of tuftsin; associated with modulation of GABAergic tone and stress-response pathways
-
Intranasal Delivery: Targets nasal mucosa for rapid onset; avoid immediate co-administration with other sprays
-
Program Fit: Non-hormonal, non-stimulant approach within a comprehensive lifestyle plan
