Reported findings and study design
Stress-resistance and anxiety indices changed in both Semax arms. The study compared delivery procedures and did not measure race performance or brain exposure.
Fifteen-day observation during precompetition training. Both arms used intranasal Semax, with laser application in the main group.
Protocol information
Intranasal 0.1% Semax in both arms. Delivered peptide mass per participant is unverified.

| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Stress-resistance index | 9.2±0.31 → 15.7±0.16 with laser; 8.5±0.24 → 10.4±0.14 with nasal application alone | Authors’ index. A reliable between-arm effect is unavailable. |
| HADS anxiety | 8.41±1.22 → 5.16±0.12 vs 8.83±1.66 → 5.96±0.21 | Within-group p<0.05 for the laser arm and p>0.05 for the comparator as printed. |
A comparison of two Semax procedures, with an unresolved treatment-group flow.
