Selank and Semax are two of the most extensively researched cognitive peptides, originally developed in Russia and studied for decades in neurological and cognitive research. These synthetic peptides are of particular interest for their roles in cognitive performance, anxiety regulation, and neuroprotection.
For researchers in the UK, both peptides are available strictly for laboratory research use only, supplied by Bluewell Peptides with COA verification, HPLC testing, and >99% purity standards.
What is Selank?
Selank is a synthetic heptapeptide derived from tuftsin, a naturally occurring immunomodulatory peptide. Research studies have explored Selank for:
- Anxiolytic effects without sedation.
- Stress resilience and mood regulation.
- Cognitive support and learning enhancement.
- Immune system modulation.
Mechanisms of Action
- GABA Modulation: Enhances GABAergic neurotransmission without sedation.
- Serotonin Regulation: Supports balanced emotional states.
- Enkephalin Enhancement: Increases natural peptides linked to well-being.

What is Semax?
Semax is a synthetic peptide analogue of ACTH (4-7 fragment) and is widely researched for its neuroprotective and cognitive applications. Research suggests it may:
- Increase BDNF (Brain-Derived Neurotrophic Factor) expression.
- Improve memory and learning functions.
- Support neuroprotection and recovery after injury.
- Enhance cerebral blood flow and neurotransmitter activity.

Selank vs Semax – Key Differences
| Feature | Selank | Semax |
|---|---|---|
| Primary Research | Anxiety, stress regulation, mood, cognition | Memory, neuroprotection, brain repair |
| Mechanism | GABA & serotonin modulation | BDNF upregulation, neurotrophic activity |
| Use Cases | Studied for stress resilience & anxiolytic effects | Studied for memory & neuroprotection |
Summary
- Selank is best suited for research into stress, anxiety, and emotional regulation.
- Semax is more relevant for studies on memory, neuroplasticity, and brain recovery.
Nasal Administration in Research Settings
Both Selank and Semax are frequently studied in research settings via intranasal administration. This delivery method is of interest because it:
- Bypasses the blood-brain barrier through olfactory pathways.
- Provides higher bioavailability compared to oral routes.
- Demonstrates faster onset of action in published studies.
Important: Bluewell Peptides supplies these compounds strictly for laboratory research use only. They are not licensed as medicines and must not be used for human consumption.Administration in Research Settings
Both peptides are typically administered intranasally in research contexts. Intranasal administration allows:
- Bypassing the blood-brain barrier for efficient delivery.
- Higher bioavailability compared to oral forms.
- Faster onset, often within 15–30 minutes in studies.
Note: This information reflects published research settings. Bluewell Peptides supplies compounds strictly for laboratory use only.
Research Protocols & Considerations
In published studies, Selank and Semax have been administered across a range of concentrations. Reported research ranges include:
- Selank: 150–750 mcg, studied 1–2 times daily.
- Semax: 200–1000 mcg, studied 1–2 times daily.
Researchers often cycle administration schedules (e.g., 5 days on, 2 days off) to maintain consistency in results.
Disclaimer: These values are based on published research and are not usage recommendations. Bluewell Peptides products are not approved for human use.
Safety & Research Findings
Both Selank and Semax have undergone extensive research in clinical and preclinical contexts.
- Selank Safety Profile: No reported tolerance issues, minimal side effects in studies (e.g., mild nasal irritation).
- Semax Safety Profile: Well tolerated, with rare reports of mild nasal congestion or headache.
Important: Supplied strictly for research purposes. Not intended for human or veterinary use.
