Selank, SK5, SK10, factory direct, door-to-door delivery, high quality and purity. CAS: 129954-34-3

Selank is a neuromodulatory peptide that can relieve anxiety, calm emotional distress, and improve insomnia and neurasthenia caused by high stress. It can also enhance concentration, regulate stress hormones, and gently stabilize nerves. It is often used in combination with brain-boosting peptides and is intended for research purposes only. It should not be used on humans without authorization.

Our factory is a modern research-oriented peptide production base specializing in the R&D, synthesis, purification, and lyophilization of peptide raw materials. We have established standardized clean workshops equipped with precision equipment such as fully automated peptide synthesizers, high-performance liquid chromatographs, and vacuum lyophilizers, enabling stable mass production of mainstream GLP-1 peptide products. Our factory has a professional technical quality control team that strictly controls the entire process from synthesis, purification, lyophilization, to packaging, ensuring a finished product purity consistently above 98%. All products are uniformly packaged in lyophilized vials. Our main focus is on research-grade peptide raw materials; all products are labeled for research use only. We offer flexible customization options such as 20mg and 30mg, with a standard box containing 10 vials. We provide stable supply and customized peptide services to research institutions and biotechnology companies both domestically and internationally.

1. High Purity: HPLC verified purity ≥98% with extremely low impurities, ensuring accurate and stable experimental data.
2. Stable Molecular Activity: Adopts low-temperature lyophilization and vacuum sealing technology to avoid high-temperature oxidation and molecular chain breakage, maintaining ultra-high peptide activity retention rate.
3. Excellent Solubility: Loose and fine powder dissolves completely and rapidly in bacteriostatic water without residue or turbidity.
4. High Batch Consistency: Strict quantitative filling and content sampling inspection for each batch with minimal errors, ideal for comparative and long-term experiments.
5. Practical Package Specification: 10 independent vials for flexible use, waste reduction, convenient storage, sub-packaging and batch experiments.
6. Low Degradation & Long Shelf Life: Extremely low activity attenuation during long-term storage under standard refrigeration conditions.

Unopened, long-term storage: Freezer (-20℃), sealed and protected from light.
Unopened, for use within a few days: Refrigerator (2~8℃).
Dissolved in water: Refrigerate only (2~8℃), use within 7 days, do not refrozen.
