Selank is a synthetic heptapeptide developed from the endogenous immunomodulator tuftsin. Research models show it modulates the GABAergic system and influences BDNF expression in specific hippocampal regions. Unlike benzodiazepines, animal studies indicate its anxiolytic profile does not produce sedation, cognitive impairment, or tolerance, making it a notable investigational tool for stress-response research.

Based on 194 verified researcher orders.
Commandé le mardi, reçu le vendredi. Emballage propre, flacon intact, et le certificat était bien joint comme la fiche le promettait. Je commence déjà à voir ce que je cherchais — je commanderai à nouveau le mois prochain sans hésiter.
Research peptides are chemical reagents for laboratory analysis. Regulations vary by jurisdiction — it is the buyer's responsibility to ensure compliance with local laws. See our Terms & Conditions page for the full regulatory framework across the EU, UK, US, Switzerland, Thailand, and other major markets.
Lyophilized (unreconstituted) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerated) for short-term use. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles — aliquot into smaller portions if needed.
For laboratory research use only. Not for human consumption, diagnosis, treatment, prevention, or in-vivo administration. By purchasing you confirm you are a qualified researcher or institution.
Reconstitute the 5mg vial with 1mL bacteriostatic water → 5 mg/mL. On a U-100 insulin syringe, 5 IU = 0.05 mL = 250 mcg. Nasal spray presentation (if selected) is pre-calibrated per-actuation.
Après une mauvaise expérience avec un autre fournisseur l'année dernière j'étais sceptique. Livraison rapide, emballage scellé et étiqueté correctement, certificat d'analyse joint à la commande. La qualité justifie le prix.
What you read on the page is exactly what you get. No bait and switch, no weird substitutions, no missing items. They emailed updates at every step and the product looks and works exactly as advertised. I appreciate the transparency.
Gently inject bacteriostatic water (bacteriostatic water) along the inside wall of the vial — do not spray directly onto the powder. Let it dissolve naturally or gently swirl. Never shake vigorously. Standard reconstitution: add the desired volume of bacteriostatic water based on your concentration needs. For example, 5mg peptide + 2.5ml bacteriostatic water = 2mg/ml concentration.
Yes. Every batch undergoes independent third-party HPLC (High-Performance Liquid Chromatography) and mass spectrometry analysis. We provide a Certificate of Analysis (COA) for each product, verifying identity, purity (≥99%), and the absence of contaminants. COA documents are available for download on each product page.
Yes. We offer temperature-controlled shipping to most EU and Asian countries. Standard EU delivery is 24-48 hours. International orders are shipped in discreet, professional packaging with cold-chain protection where required. Customs documentation and regulatory paperwork are provided as needed.
We currently operate on an inquiry-based ordering system. Submit your order through checkout and our team will contact you within 24 hours to confirm details and arrange payment. We are working on integrating direct payment options for a seamless experience.
