COGNITIVE & NOOTROPIC STACK
Semax + SelankBDNF upregulation + anxiolytic
Synergy: Semax is an ACTH-derived heptapeptide that increases BDNF and modulates dopaminergic signaling; Selank is a Tuftsin-derived peptide with anxiolytic activity via GABA modulation. The pairing covers both cognitive enhancement and anxiety/stress regulation.
Stack components
Semax
Cognitive
Nootropic heptapeptide supporting BDNF, focus, memory, and mood.
500 µg draw on 100u syringe
Selank
Cognitive
Anxiolytic peptide based on tuftsin, supporting calm focus and immune modulation.
500 µg draw on 100u syringe
Injection timing
Both intranasal, dosed 1 to 3 times daily. Separate by 5 minutes between sprays to avoid runoff.
Same syringe or separate?
Separate intranasal sprays; do not co-administer in one nostril at once.
Typical cycle length
2 to 4 weeks per cycle, with breaks. Tolerance and tachyphylaxis can develop.

Frequently asked
What does the Semax + Selank stack do?
Semax is an ACTH-derived heptapeptide that increases BDNF and modulates dopaminergic signaling; Selank is a Tuftsin-derived peptide with anxiolytic activity via GABA modulation. The pairing covers both cognitive enhancement and anxiety/stress regulation.
When should Semax and Selank be injected?
Both intranasal, dosed 1 to 3 times daily. Separate by 5 minutes between sprays to avoid runoff.
Can Semax and Selank be drawn into the same syringe?
Separate intranasal sprays; do not co-administer in one nostril at once.
How long is a typical Semax + Selank cycle?
2 to 4 weeks per cycle, with breaks. Tolerance and tachyphylaxis can develop.
What dose of Semax pairs with Selank?
Standard ASCEND reference dose for Semax: 500 µg from a 10 mg vial reconstituted with 2 mL bacteriostatic water (5000 µg/mL). Draw volume at this concentration: 0.1 mL, which is 10 IU on a 100-unit insulin syringe. Adjust to the research protocol you are following.
