About this peptide

This spray combines two Russian-developed nootropic peptides in one bottle: Semax, an ACTH-fragment studied for focus, memory and neuroprotection, and Selank, a tuftsin analogue studied for calm and anxiety without sedation. Run together they are the classic focus-plus-calm stack: Semax for clear, sustained attention and Selank to take the edge off without dulling you. It is a ready-to-use intranasal spray, nothing to reconstitute and no injecting, which is the route both peptides were clinically researched on in Russia. Both are approved medicines in Russia; outside Russia they are research compounds with limited independent trials. Supplied for research use only.

What it does

A one-spray focus-and-calm stack. Semax drives clear, sustained attention, verbal fluency and mental stamina; Selank steadies the nerves and eases anxiety without the fog or sedation of benzodiazepines. Popular with professionals and knowledge workers who want to be switched on but not wired. Delivered needle-free as an intranasal spray with nothing to mix. A cognition-and-mood peptide stack rather than a physical one.

What to expect

  1. Week 1

    Two-speed: Semax focus and verbal fluency often within 15 to 40 minutes of a spray, while Selank calm builds over minutes to a few hours. A mild headache or nasal irritation is possible early.

  2. Weeks 2-4

    The consistent window: steady focus and mental stamina from Semax, a calmer baseline and lower anxiety from Selank.

  3. Weeks 4-12

    Plateau in community protocols; most users cycle off around here rather than run continuously.

  4. Long term

    Uncharacterised in humans for either peptide beyond short courses; pulsed cycling is the consensus approach.

A rough guide drawn from research and community reports. Individual results vary and nothing here is a promise.

Side effects & cautions

Key points

Suits the nootropic-minded crowd and professionals who want focus and calm at once, without juggling two separate products. A natural all-in-one for anyone who would otherwise run Semax and Selank side by side. Less relevant to fat-loss, recovery or hormonal goals.

Two mechanisms in one spray. Semax is a synthetic ACTH(4-10) fragment that raises brain-derived neurotrophic factor (BDNF) and influences dopamine and serotonin signalling, without the cortisol effect of ACTH, which is the basis for interest in focus and neuroprotection. Selank is a synthetic tuftsin analogue that influences GABA and serotonin signalling and BDNF expression, the basis for interest in calm and anxiety, reportedly without the sedation of benzodiazepines.

Reported effects are mild and mostly the same as the two peptides alone: short-lived nasal irritation or dryness from the spray, occasional headache, and, from the Semax side, some raised caffeine sensitivity or feeling wired if run for long stretches without a break. Much of the clinical evidence is Russian and harder to verify independently, so wider-population effects are not established. One note from the research: avoid stacking this with PT-141 or oxytocin at the same time. Purity matters, and a Certificate of Analysis is shared where our supplier provides one.

Ready-to-use intranasal spray, no reconstitution needed. Each spray delivers both peptides together. Store cool and out of light (the fridge is ideal), keep the cap on, and prime the pump with a spray or two before first use. Use within the period stated on the label once opened.

Questions about Semax + Selank Nasal Spray

No. It is a ready-to-use nasal spray, no bacteriostatic water and no syringe. You spray it into the nose.

They are the classic nootropic pairing: Semax for focus and drive, Selank to keep you calm and clear rather than wired. This spray gives you both in one.

In practice most run roughly 0.5 to 1 mg of each once a day, in short 2 to 3 week cycles. Heavier, productivity-focused users sometimes take it twice a day. See our protocols page and your product insert for specifics. Supplied for research use only.

Both are approved medicines in Russia. Elsewhere they are research compounds, and we make no therapeutic claims.
