Protocol Stack

Semax

Primary

Dose

600 mcg

Frequency

Daily intranasal

Timing

Morning, alternating nostrils

Duration

5 days on / 2 days off cycles throughout 8 weeks

Selank

Primary

Dose

250 mcg

Frequency

Daily intranasal

Timing

Afternoon or as-needed for anxiety

Duration

8 weeks (can use PRN on high-stress days)

Dihexa

Optional

Dose

10 mg

Frequency

Daily oral

Timing

Morning with food

Duration

Weeks 1–4 only (high potency, short course)

Monitoring Parameters

✓Standardized cognitive assessment (MoCA or CNS Vital Signs) — baseline and week 8
✓Anxiety score (GAD-7) — weekly
✓Sleep quality (PSQI) — baseline, week 4, week 8
✓Blood pressure (Semax can cause mild transient elevation) — weekly
✓Mood tracking — daily brief assessment

Expected Outcomes

Days 1–7: Semax effect often noticeable within first 72h — increased mental clarity

Weeks 2–3: Selank anxiety reduction measurable, sleep quality improving

Weeks 4–6: Working memory and task-switching performance improvements

Week 8: Comprehensive neuropsychological reassessment; consider 4-week break then repeat

Contraindications

✗Active psychosis or schizophrenia spectrum disorders
✗Uncontrolled hypertension (Semax contraindicated)
✗Concurrent use of MAO inhibitors
✗Bipolar disorder — stimulant peptides may trigger manic episodes
✗Epilepsy (Semax lowers seizure threshold in susceptible individuals)

Clinical Notes

Semax (ACTH 4-7 analog) upregulates BDNF, dopamine, and serotonin — producing stimulant-like focus enhancement. Selank (tuftsin analog) has anxiolytic effects comparable to benzodiazepines without tolerance or dependence. This combination is particularly effective for high-performing individuals with stress-related cognitive decline. Intranasal delivery requires proper technique — solution should not run into throat.

Case Study

Clinical Practice Example

Female surgeon, 47, reporting 'brain fog' post-COVID with impaired processing speed and word-finding difficulty. MoCA baseline 24/30. Started Semax + Selank protocol. At week 4, she described her cognition as 'back to pre-COVID baseline'. MoCA at week 8: 29/30. Sustained improvements in working memory and surgical decision speed self-reported at 3-month follow-up.
