FAQ
Selank — Frequently asked questions
What is Selank?
Selank (TP-7) is a synthetic heptapeptide analog of the immunomodulatory tetrapeptide tuftsin. Developed at the Russian Academy of Medical Sciences, studies describe effects on GABAergic, serotonergic and BDNF systems — anxiolytic and nootropic. CAS 129954-34-3.
How is Selank typically used?
Selank is most commonly used as a nasal spray (intranasal) at 75-300 mcg per nostril, 2-3 times daily. The 5mg vial reconstituted in 2mL of saline yields 2.5mg per mL — 0.1mL delivers 250 mcg. Subcutaneous injection is less common.
How is Selank tested?
Each Selank lot is HPLC-tested to ≥99% purity, confirmed by ESI mass spectrometry, and LAL endotoxin tested below 0.5 EU/mg. ISO 17025-accredited third-party labs perform the testing.
How do I store Selank?
Lyophilized Selank is stable at -20°C for 24+ months. After reconstitution, store refrigerated at 2-8°C and use within 30 days.
