Cognitive — Nootropic Peptide Stack
Semax + Selank + Dihexa — focus, clarity, neuroprotection.
Overview
Three peptides with distinct mechanisms targeting cognition and neural function. Semax (BDNF modulator, focus/clarity), Selank (anxiolytic without sedation), and Dihexa (angiotensin IV analog, documented synaptogenesis effects in published studies). Intranasal administration is the common route for Semax and Selank — convenient and faster onset than subcutaneous. Dihexa is typically oral or topical.

Weekly Protocol
All three run the full 8 weeks. Onset is fastest for Semax (days) and slowest for Dihexa (weeks). Intranasal reconstitution for Semax/Selank: bacteriostatic saline, small-volume spray bottle, refrigerated once mixed.
| Compound | Dose | Frequency | Weeks |
|---|---|---|---|
| Semax | 0.3 mg | 2× daily | 1-8 |
| Selank | 0.3 mg | 2× daily | 1-8 |
| Dihexa | 15 mg | Daily | 1-8 |
Expected Outcomes
- Measurable focus improvement within 3–7 days (Semax)
- Reduced baseline anxiety (Selank)
- Enhanced memory formation under learning load (Dihexa)
- No hormonal effects, no PCT required
Safety & Warnings
- Dihexa human data is limited — all human reports are anecdotal. Treat as investigational.
- Intranasal reconstitution requires sterile technique and fresh BAC water.
- Dihexa is lipophilic and potentially accumulates in brain tissue — no long-term data on extended use.
Frequently Asked
Will this make me smarter?
No nootropic 'makes you smarter.' These modulate attention, anxiety, and neural plasticity — you still have to do the work. But the feedback loop on learning, focused work, and sleep quality is often measurably improved.
Can I stack this with caffeine / nicotine?
Caffeine: yes, compatible. Nicotine: also compatible but separate mechanism. Stacking peptide nootropics with stimulants doesn't compound — they work on different axes.
