Overview
A pre-mixed cognitive blend combining Semax and Selank for neuroprotection and anxiolytic research protocols. Intranasal delivery is common in the literature; injectable reconstitution requires protocol-specific validation. Nootropic blend pairing BDNF-upregulating Semax with GABAergic anxiolytic Selank.

Stability & storage phases
| Phase | Condition | Guidance |
|---|---|---|
| Lyophilized blend | Refrigerated (2–8 °C), sealed | Confirm per-peptide mg breakdown on analytical documentation before storage; blended cakes may dissolve more slowly than single-peptide vials. |
| Reconstituted | Bacteriostatic water, refrigerated | Gently swirl until all components dissolve; stability limited by the most labile peptide in the mixture — label total and per-component concentration. |
| Working aliquots | Frozen (−20 °C) aliquots with component ratio noted | Calculate per-peptide exposure from verified blend ratios only; do not assume equal mg across components without analytical composition verification. |
Stability windows are formulation-dependent — verify published data and your lab SOP.
Reconstitution reference table
| Vial (mg) | Diluent (mL) | mcg/mL | Units @ 100 mcg | Units @ 250 mcg | Units @ 500 mcg |
|---|---|---|---|---|---|
| 5 | 2 | 2500.0 | 4 | 10 | 20 |
| 10 | 2 | 5000.0 | 2 | 5 | 10 |

Reconstitution steps
- Confirm per-peptide composition from analytical documentation before any calculations
- Allow vial to reach room temperature (15–30 min)
- Swab stopper; inject diluent slowly down vial wall
- Gently swirl — blends may take longer to fully dissolve
- Label with date, total concentration, and component note
- Refrigerate; calculate per-peptide dose from verified ratios
Often used intranasally in research; injectable reconstitution per protocol.
