Semax + Selank Blend
Focus + calm cognitive blend
Focus meets calm — the classic Russian nootropic pairing in a single vial.
Research chemical vendors can't legally label products with the real name, so Semax + Selank Blend often appears under coded SKUs. If you're shopping and see any of these, it's the same compound:
- Focus Stack
- Semax+Selank
Codes shown are for identification only. Always verify third-party COAs before purchase.
Semax is a heptapeptide fragment of ACTH that raises BDNF, dopamine, and serotonin — sharpening focus and neuroprotection. Selank is an analog of tuftsin that modulates GABA and reduces anxiety without sedation. Together they produce alert calm — the profile most nootropic stacks are chasing.
Intranasal is common for both compounds and works well; subcutaneous is more consistent for daily dosing.
- Focus and mental clarity without stimulant jitters
- Anxiety, social stress, and burnout recovery
- Post concussion and traumatic brain injury protocols
- ADHD adjacent focus support

Typical timeline
General pattern for the Neuro Cognition category. Individual response varies.
- Day 1–3Effect can be felt within hours: calmer focus (Selank), sharper attention (Semax), or deeper sleep (DSIP).
- Weeks 1–4Consistent daily benefits. Mood and cognitive stamina improve without stimulant crash.
- Post-cycleTake a break to avoid tolerance. Most users cycle 8 on / 8 off.
The reconstitution math
- 1Reconstitute the 20 mg vial with 2 mL of bacteriostatic water. Tilt — don't shake.
- 2Concentration becomes 10,000 mcg/mL (10 mg/mL).
- 3For a 2 mg dose, draw 0.200 mL — that's 20 units on a 1 mL insulin syringe.
- 4One vial gives you approximately 10 doses.
Reminder: 100 units on an insulin syringe = 1 mL. Always start at half the listed dose for the first week and rotate injection sites between arms, legs, abdomen, and glutes.
