8-week nootropic protocol backed by 25+ years of Russian clinical research and 6 peer-reviewed studies
Semax is a synthetic heptapeptide analog of ACTH(4-10) — the active fragment of adrenocorticotropic hormone responsible for cognitive effects independent of adrenal stimulation. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences by Nikolai Myasoedov and colleagues, Semax has been approved in Russia since 2001 for treatment of stroke, cognitive disorders, optic nerve atrophy, and as a general nootropic.

Co-developer of Semax. Lead researcher on ACTH-derived neuropeptides for over 30 years. Holds multiple patents on Semax and its analogs.
Semax represents a new class of nootropic drugs based on regulatory peptides. It has a unique combination of nootropic, neuroprotective, and neurotrophic activity that has been confirmed in extensive clinical practice.
Standard nootropic dose ~600 mcg/day subcutaneously, split into 2-3 doses. For acute neuroprotection: higher doses under supervision. 10-14 day treatment courses.

Dr. Andrew Huberman
Professor of Neurobiology, Stanford University
Ph.D. in Neuroscience. Host of Huberman Lab podcast. Expert in BDNF, neuroplasticity, and visual system neuroscience.
BDNF is the key molecule for neuroplasticity — it strengthens existing synapses and promotes the formation of new ones. Compounds that reliably increase BDNF in the hippocampus have enormous implications for learning and memory.
Focus on BDNF upregulation as the primary cognitive mechanism. Combine with behavioral interventions that also boost BDNF: exercise, novel learning, and adequate sleep.

Dr. Neil Paulvin
Functional & Regenerative Medicine Physician, Manhattan
Known as 'Dr. Peptide.' Integrates Russian neuropeptide research into Western functional medicine. Treats high-performance individuals seeking cognitive optimization.
Semax is one of the best-studied nootropic peptides we have. It's approved in Russia, used by hundreds of thousands of people, and has a remarkably clean safety profile. It's my go-to for patients who want pure cognitive enhancement.
300-600 mcg/day subcutaneously for cognitive enhancement. Can titrate up to 900 mcg/day for acute cognitive demand. Pairs exceptionally well with Selank for anxious high-performers.

Dr. William Seeds
Founder, SSRP Institute
40+ years in cellular and molecular medicine. Author of 'Peptide Protocols: Volume 1'. Expert in clinical peptide therapy applications.
The ACTH-derived nootropic peptides like Semax offer a mechanistically clean approach to cognitive enhancement — neurotrophin upregulation rather than neurotransmitter flooding. This is sustainable cognitive improvement.
200-600 mcg subcutaneously per day. Standard 4-8 week cycles. Monitor for overstimulation at higher doses. Combine with Selank for balanced nootropic-anxiolytic protocols.

Protocolo de Dosificación
3 FasesRégimen de dosificación paso a paso compilado de profesionales líderes e investigación clínica.
Start conservatively. Semax has a very short serum half-life (~3-5 min) but CNS effects persist for hours after subcutaneous delivery. Rotate injection sites. Morning dosing recommended for daytime cognitive benefit.
Matches the Russian-approved dosing regimen. Multiple daily doses compensate for the short half-life. Rotate injection sites between abdominal quadrants. Peak BDNF upregulation and cognitive effects during this phase.
Taper to assess sustained neuroplastic benefits. Russian clinical protocols often use 10-14 day courses; Western practitioners typically extend to 4-8 weeks. Plan 2-4 week washout.
Add 1 mL bacteriostatic water to 5 mg vial = 5,000 mcg/mL. Use an insulin syringe for precise subcutaneous dosing. 200 mcg = 4 units (0.04 mL); 600 mcg = 12 units (0.12 mL).
Russian clinical standard: 10-14 day courses with 10-14 day intervals. Western practitioners: 4-8 weeks on, 2-4 weeks off. Semax shows minimal tolerance development but cycling maintains optimal melanocortin receptor responsiveness.
Lyophilized: -20°C for 24+ months. Reconstituted: 2-8°C, use within 30 days. Protect from light and heat.
Subcutaneous injection into the abdominal fat pad is the recommended route. Use a 29-31 gauge insulin syringe. Pinch a fold of skin, insert at a 45-degree angle, and inject slowly. Rotate injection sites between abdominal quadrants to prevent lipodystrophy.

Mecanismo de Acción
4 vías biológicas distintas a través de las cuales opera este péptido.
BDNF & Neurotrophin Upregulation
Potently stimulates transcription and translation of BDNF, NGF, and their receptors TrkB and TrkC in hippocampus and cortex — the molecular basis for enhanced learning and memory.
- BDNF mRNA increased in hippocampus within 3 hours of administration
- TrkB receptor co-upregulated — amplifying downstream signaling cascades
- NGF also elevated — supporting cholinergic neuronal health critical for memory
- Effects persist well beyond the peptide's serum half-life due to transcriptional activation
Dolotov et al. (2006) PMID: 16413131; Agapova et al. (2008) PMID: 18236012
Melanocortin Receptor Activation (MC3/MC4)
As an ACTH(4-10) analog, Semax activates melanocortin receptors MC3R and MC4R in the CNS, modulating attention, arousal, and memory consolidation.
- MC4R activation in hippocampus enhances long-term potentiation (LTP)
- Modulates dopaminergic signaling for improved motivation and reward-driven learning
- No adrenal stimulation — cognitive effects are independent of cortisol elevation
- Pro-Gly-Pro extension provides enzymatic stability without altering receptor selectivity
Levitskaya et al. (2004); General melanocortin receptor pharmacology
Neuroprotection Against Ischemia
Provides multi-pathway neuroprotection against ischemic and oxidative brain damage — the mechanism behind its Russian approval for stroke treatment.
- Counteracts ischemia-induced gene expression changes within 24 hours
- Restores anti-apoptotic gene programs suppressed by oxygen deprivation
- Enhances antioxidant enzyme activity (SOD, catalase) in neural tissue
- Reduces infarct volume and improves neurological outcomes in animal stroke models
Medvedeva et al. (2014) PMID: 25380972; Kaplan et al. (1996) PMID: 8953246
Broad Genomic Modulation
Whole-genome analysis reveals Semax modulates over 24 functional gene groups simultaneously — a remarkably broad mechanism explaining its diverse clinical effects.
- Neurotransmitter transport and receptor genes upregulated
- Immune response and inflammation resolution genes activated
- Vascular regulation and angiogenesis gene programs modulated
- Effect pattern explains why Semax has cognitive, neuroprotective, and immunomodulatory activities simultaneously

Potencia tu Protocolo de Investigación
4 SinergiasLa investigación sugiere combinar Semax con estos péptidos para mecanismos complementarios.

The classic Russian neuropeptide combination developed at the same institute. Semax provides cognitive enhancement while Selank provides anxiolysis — together, they deliver focused cognition without anxiety.
Russia's most prescribed nootropic combination. Calm, focused cognitive enhancement without the anxiety that can accompany pure nootropics or the sedation that accompanies anxiolytics.

Adamax is the enhanced-stability version of Semax. Using both allows acute Semax dosing for immediate cognitive needs plus Adamax for sustained neurotrophin support.
Complete neurotrophin coverage: Semax for acute cognitive peaks, Adamax for sustained baseline enhancement. Alternate rather than combine for optimal receptor management.

P21 promotes neurogenesis and acts as a BDNF mimetic, complementing Semax's endogenous BDNF upregulation through an independent pathway.
Dual neurotrophin strategy: endogenous BDNF production (Semax) plus direct TrkB activation (P21). Comprehensive support for both synaptic plasticity and new neuron formation.

Pinealon is a short bioregulator peptide that modulates pineal function and circadian neurotransmitter balance, complementing Semax's daytime cognitive enhancement.
24-hour cognitive optimization: Semax for daytime performance, Pinealon for nighttime neural restoration. Supports the sleep-dependent memory consolidation that locks in daytime learning.
Especificaciones
Cómo Funciona Semax
Semax is a synthetic heptapeptide analog of ACTH(4-10) with a stabilizing Pro-Gly-Pro extension. It increases BDNF and TrkB receptor expression, enhances neurotrophic factor signaling, modulates dopaminergic and serotonergic neurotransmission, and provides neuroprotection through antioxidant and anti-inflammatory mechanisms. Unlike ACTH, Semax has no steroidogenic activity. It improves cerebral circulation, enhances memory consolidation, and has been approved in Russia and Ukraine for stroke recovery and cognitive enhancement.
