Product Introduction & Core Mechanism
Selank is a synthetic stabilized heptapeptide analog of natural tuftsin, originally developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. The added C-terminal Pro-Gly-Pro tripeptide greatly boosts metabolic stability and central nervous system bioavailability, delivering multi-target neuropsychotropic, nootropic and immune-regulating effects without sedation, dependence or cognitive impairment common to benzodiazepine anxiolytics.
Core research mechanisms:
- Mild GABAergic modulation for natural anxiety relief
Inhibits GABA-degrading enzymes and upregulates GABA-A receptor subunit expression to calm overactive neural signaling. It eases stress, nervous tension and emotional unease without brain fog, drowsiness or addictive potential. - Balance serotonin & dopamine neurotransmitters
Regulates monoamine metabolism in prefrontal cortex and hippocampus to stabilize mood, ease irritability and lift chronic mental fatigue under stress models. - Upregulate BDNF to support cognition & neuroplasticity
Stimulates endogenous BDNF synthesis, strengthens synaptic connections, improves focus, working memory and learning capacity during long-term mental strain research. - Anti-stress & anti-inflammatory immune balance
Suppresses overproduction of pro-inflammatory cytokine IL-6, restores Th1/Th2 equilibrium and reduces chronic neuroinflammation triggered by prolonged stress; also retains tuftsin’s innate immune activation function for macrophages and NK cells. - Endogenous enkephalin preservation
Blocks enzymes that break down enkephalins to extend natural stress-resistance signaling, supporting emotional resilience without opioid side effects.
Our Selank Product Competitive Advantages
- Ultra-high purity ≥99%
Every batch passes HPLC and LC-MS mass spectrum verification. Complete COA, HPLC chromatogram, heavy metal and low-endotoxin test reports (third-party lab testing available) are provided for all bulk orders; no degraded peptide fragments or impurity residues. - Vacuum freeze-drying production
Full moisture removed with zero preservatives to lock complete peptide biological activity. Solid lyophilized form resists oxidation and hydrolysis during long-distance air & sea cross-border shipping, maintaining stable potency over 24-month shelf life. - GMP sterile cleanroom manufacturing
Individually sealed single vial packaging to avoid cross-contamination. Custom private labels, bottle dimensions and bulk bulk packaging services are offered for global resellers and lab suppliers. - Superior water solubility
Rapidly dissolves in bacteriostatic water to form fully transparent, sediment-free solution, enabling precise laboratory dosage preparation for in vitro and preclinical trials. - Complete technical support kit
We supply official reconstitution protocol, storage guidelines, laboratory dosage reference data and full batch traceability documents for all distributors.
Storage & Reconstitution Instructions
- Unopened lyophilized powder: Long-term storage at -20°C away from light and humidity, shelf life up to 24 months; short transit storage at 2–8°C is acceptable.
- Recommended solvent: Sterile bacteriostatic water
- Operation tip: Slowly inject solvent along the inner vial wall and swirl gently; violent shaking causes peptide aggregation and activity loss.
- Reconstituted liquid: Seal tightly and refrigerate at 2–8°C, finish all usage within 14 days; avoid repeated freeze-thaw cycles.
