Key Research Areas:
- Anxiolytic & Mood Regulation — Selank demonstrates notable anti-anxiety and antidepressant-like effects without inducing sedation. Both clinical and animal studies suggest it works by modulating GABAergic receptor activity and serotonin metabolism, resulting in reduced anxiety and greater emotional stability under stress.
- Cognitive Function & Memory Support — In animal models, Selank has been shown to improve learning capacity, memory retention, and attention — especially under stress or withdrawal conditions — by helping regulate neuropeptide and neurotransmitter balance through GABA and serotonin pathway modulation.
- Neurotransmitter System Modulation — Selank interacts with several key neurotransmitter systems, including GABA, serotonin, and dopamine. It influences gene expression related to neurotransmission and may inhibit enzymes responsible for breaking down enkephalins, thereby amplifying natural neuropeptide activity and supporting calm, focused states.
- Gene Expression & Neuroplasticity — Research indicates Selank modifies the expression of genes associated with neuroplasticity and neurotransmission in the frontal cortex and hippocampus, pointing to a potential role in the long-term regulation of neural adaptation and stress response.
- Immune System & Anti-Inflammatory Effects — As a derivative of the immunomodulatory peptide tuftsin, Selank has been shown to restore cytokine balance by reducing pro-inflammatory markers (IL-1β, IL-6, TNF-α) while elevating IL-4, supporting immune homeostasis during periods of psychological or physiological stress.
- Stress Resilience & Neuroendocrine Regulation — Selank appears to stabilize the hypothalamic–pituitary–adrenal (HPA) axis, dampening the overactivation associated with chronic stress. This may contribute to improved resilience, better energy regulation, and faster recovery from stress-related fatigue.
- Oxidative & Metabolic Protection — Preclinical findings suggest Selank may help lower oxidative stress markers and lipid peroxidation, providing mild neuroprotective benefits by preserving redox balance and supporting cellular metabolism under stress conditions.
- Antiviral & Homeostatic Effects — Experimental data indicate Selank may bolster antiviral immune defenses by shifting Th1/Th2 cytokine ratios and promoting balanced immune regulation, potentially strengthening the body’s response during viral challenges.
Product Care & Storage:
- Shipping & Stability — All products are lyophilized prior to shipping, maintaining stability in transit for up to 3–4 months. Reconstitution with bacteriostatic water is required before research use.
- Lyophilized / Powder Form — Store in a cool, dry location away from direct light. Room temperature storage is suitable for several weeks. For long-term preservation spanning months to years, freezing is the optimal method to maintain potency and integrity.
- Reconstituted Form — Once mixed, refrigerate below 39°F. Stability is maintained for up to 30 days.
- Usage — We are unable to provide dosing guidance; however, all products are considered pharmaceutical grade.
- Disclaimer — This product is intended strictly for research purposes and is not approved for human consumption, clinical treatment, or diagnostic use. Standard laboratory safety protocols should be observed at all times when handling peptides.
