About this peptide

Semax is a Russian-developed nootropic peptide based on a fragment of the hormone ACTH, but without the cortisol effect. This is the ready-to-use intranasal spray: nothing to reconstitute and no injecting, and intranasal is the route used in Semax clinical research in Russia and the way most people run it anyway. It is studied for focus, memory and brain protection, and is an approved medicine in Russia for stroke and cognitive conditions. Outside Russia it is a research compound and independent large trials are limited. Supplied for research use only.

What it does

Researched for mental focus, clarity and cognition, with interest in mood, motivation and recovery from mental fatigue. The entrepreneur and knowledge-worker crowd explore Semax as a focus and deep-work aid; nootropic users run it for ease of finding words and learning; athletes have used it for post-training brain fog. This is the intranasal spray, the route most people run Semax on anyway, ready to use with nothing to mix. A cognition-focused peptide rather than a physical one.

What to expect

  1. Week 1

    Fast. Focus and verbal fluency are often noticeable within 15 to 40 minutes of an intranasal dose; a mild headache or nasal irritation is possible.

  2. Weeks 2-4

    Most consistent community window for focus, mental endurance and word recall.

  3. Weeks 4-12

    Plateau in community protocols; Russian clinical use does not extend this long.

  4. Long term

    Uncharacterised in humans; pulse-courses are the validated paradigm.

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

Key points

Suits the nootropic-minded crowd, professionals chasing focus and mental stamina, and anyone researching cognition or neuroprotection, provided they are comfortable that most clinical evidence comes from Russian studies. A natural pair with Selank for a focus-plus-calm stack. Less relevant to fat-loss, recovery or hormonal goals.

Semax is a synthetic fragment analogue of ACTH that, unlike ACTH, does not raise cortisol. Research describes it increasing brain-derived neurotrophic factor (BDNF) and influencing dopamine and serotonin signalling, which is the basis for interest in focus and neuroprotection.

Reported effects include short-lived nasal irritation from the spray, headaches, and feeling over-stimulated or wired if used for long stretches without a break; some find it raises caffeine sensitivity. Much of the clinical evidence is Russian and harder to verify independently, so wider-population effects are not established. Purity matters, and a Certificate of Analysis is shared where our supplier provides one.

Ready-to-use intranasal spray at 2.5 mg/ml, no reconstitution needed. 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 Nasal Spray

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

In practice most run roughly 0.5 to 1 mg 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.

It is an approved medicine in Russia and some neighbouring countries. Elsewhere it is a research compound. We supply it for research use only and make no therapeutic claims.

Most studies are Russian-language and harder to verify independently, so we describe the research carefully rather than overstate it.
