Selank Peptide – 5mg
Selank is a synthetic heptapeptide analog of the endogenous tetrapeptide tuftsin, developed as a research tool for investigating neuropeptide-based modulation of mood, cognition, and immune response. It is classified as an anxiolytic peptide with no reported sedative or addictive properties in preclinical studies. Selank has been studied for its influence on neurotransmitter systems, including GABAergic, serotonergic, and dopaminergic pathways, as well as for its potential immunomodulatory and neuroprotective effects.
Overview
Selank was engineered by substituting a stable tripeptide Pro-Gly-Pro extension to tuftsin, enhancing its metabolic stability and half-life. Studies suggest Selank may regulate expression of brain-derived neurotrophic factor (BDNF) and modulate levels of monoamines and GABA, contributing to its anxiolytic and antidepressant-like effects in animal models.
In addition to neurological research, Selank has been explored for immunomodulatory effects, including cytokine regulation and antiviral activity. This peptide is a focus of interest in experimental psychiatry, stress response research, and neuroinflammation studies.

Research and Clinical Studies
Anxiolytic and Antidepressant Models
Selank demonstrates anxiolytic activity in preclinical studies comparable to benzodiazepines, but without sedative, withdrawal, or dependency effects. Mechanistic data indicate modulation of GABA receptor expression and neurosteroid production.
Neurotransmitter and BDNF Regulation
Research shows Selank can normalize serotonin and dopamine turnover while increasing BDNF expression in hippocampal neurons, suggesting a neurotrophic role.
Immunomodulation and Antiviral Properties
Selank modulates pro- and anti-inflammatory cytokines, supporting its evaluation in neuroimmune disorders. In vitro studies suggest antiviral activity against respiratory viruses.
Cognitive and Memory Research
Selank has been investigated for its nootropic potential, showing improved learning, memory retention, and reduced cognitive impairment in animal models of stress and neurodegeneration.
Safety and Pharmacokinetics
Selank is non-toxic in preclinical studies, rapidly penetrating the blood-brain barrier, and metabolically stable due to its engineered structure, making it suitable for neuropharmacological research.
Selank peptide is available for research and laboratory purposes only. Not for human consumption.

How do I know the peptides I order are exactly what the label says?
Every vial we sell comes from a lab that follows current Good Manufacturing Practices (cGMP). That means each step of production is documented and controlled. Before a batch is released, it’s tested by independent third-party labs for purity, identity, and sterility. Certificates of analysis are available so you can see the exact test results.
Are your peptides produced in a sterile and controlled environment?
Yes. The labs we work with use ISO-certified clean rooms where air quality, equipment, and handling procedures are tightly regulated. Staff are trained to pharmaceutical-grade standards. This ensures the peptides are produced in an environment that minimizes contamination risks.
What about shipping? Do the peptides remain stable in transit?
Peptides in lyophilized (freeze-dried) form are stable at room temperature for transport. Once you receive them, refrigeration is recommended to maintain long-term integrity. We package every order securely to prevent damage and ship promptly, so your vials arrive in optimal condition.
How do I know you actually make these peptides yourselves?
We operate under strict in-house protocols that follow current Good Manufacturing Practices (cGMP). That means our team oversees the entire process from sourcing raw amino acids to the final lyophilized vial. Nothing is outsourced or repackaged. This gives us full control over purity, consistency, and sterility, and it’s why we can stand behind every single vial we ship.
What should I do with the vials once they arrive?
Store them in the refrigerator, away from direct light and heat. If you need to keep them longer, some peptides can be stored frozen. Each vial comes with clear handling instructions so you know the proper conditions for stability.
What proof do you have that your peptides are legitimate?
The strongest proof is transparency. For every peptide, we can provide certificates of analysis, manufacturing documentation, and references to the published scientific research behind it. If you ever have questions, we’ll show you the data rather than ask you to take our word for it.
