About Semax
Semax Lyophilized — a synthetic heptapeptide based on the ACTH(4-10) fragment, in lyophilized powder form for subcutaneous administration. Originally developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. Widely studied for its effects on BDNF expression, cognitive function, and neuroprotection.
Synthetic heptapeptide based on the ACTH(4-10) fragment. Approved in Russia as a nootropic since the 1990s. Studied for BDNF expression, cognitive function, and neuroprotection.
Heptapeptide analog of ACTH(4-7) with C-terminal Pro-Gly-Pro extension. Increases BDNF protein levels (1.4-fold) and trkB tyrosine phosphorylation (1.6-fold), upregulates BDNF mRNA (3-fold) and trkB mRNA (2-fold) in hippocampus, modulates serotonergic and dopaminergic neurotransmission, activates MAPK/ERK signaling cascades.
Mechanism clarity: Well-characterized (BDNF upregulation, trkB phosphorylation, MAPK/ERK signaling)

Key takeaways
-
Research score 7/10
300+ published studies in the dataset
-
Evidence tier: Emerging
Approved in Russia since 1990s. Multiple animal and human studies on BDNF, cognitive function, and neuroprotection.
-
Reality tier: Established
Approved prescription medication in Russia. Clinical data for stroke recovery and cognition. Not FDA-approved in US.
-
Human data
Russian clinical trials and prescription use data; limited Western RCTs
Storage and handling
Lyophilised powder: Room temp or refrigerated
After reconstitution: Refrigerate at 2-8°C, use within 14-21 days
Reconstitution steps from the dataset
- Prepare. If using pre-made nasal spray, skip to step 5. For powder reconstitution: clean vial top with alcohol.
- Add saline. Draw 2mL bacteriostatic saline (NOT water) and inject slowly into vial.
- Dissolve. Gently swirl until fully dissolved. Solution should be clear.
- Transfer. Transfer solution to a sterile nasal spray bottle using a syringe. Each spray ≈ 0.1mL (200mcg at 5mg/mL).
- Administer. Tilt head back slightly. Insert nozzle into nostril and spray once. Alternate nostrils. Standard dose: 1-3 sprays (200-600mcg) 2-3x daily.
- Store. Refrigerate nasal spray. Use within 14-21 days after reconstitution.
Safety and limitations
Studied for: Cognitive enhancement, Stroke recovery, BDNF modulation, Neuroprotection, ADHD symptom management
Reported onset: 5-15 minutes intranasal; 15-30 minutes subcutaneous
Reported duration: 2-4 week cycles on, 2 weeks off (Russian clinical protocol: 10-20 days)
Community reports: Polarizing. Responders describe "clean stimulant without jitters" — improved focus, verbal fluency, and working memory. Non-responders notice nothing. Some report increased irritability at higher doses. Quality varies significantly between vendors. N-Acetyl Semax Amidate considered most potent form.

... Semax definitely helped make me feel “normal” throughout the day. I have just run out and I can feel a huge difference from coming off. Will definitely be ordering more

Questions about Semax
Questions and answers recorded for this product.
Intranasal is the standard route used in Russian clinical practice and most research protocols. It provides rapid onset (5-15 minutes) and bypasses first-pass metabolism. Subcutaneous injection is less common but used by some researchers. The nasal spray format is preferred for convenience and established dosing protocols.
No. Semax is supplied as a ready-to-use nasal spray — no reconstitution or injections required.
Semax is an approved prescription medication in Russia for stroke recovery and cognitive disorders. It is sold for research purposes in the US.
