Selank is a synthetic heptapeptide (MW 751.86 Da) studied as an anxiolytic and nootropic. It is supplied as a lyophilized powder and, like Semax, is commonly used intranasally in research — a consideration when evaluating vendors.
What to Look for When Sourcing Selank
Require a third-party COA confirming ≥98% purity by HPLC and the correct 751.86 Da molecular weight. For intranasal research use, sterile handling and sealed vials are important.
Typical Price Range
Research-grade Selank typically costs around $25–$45 per vial. As with all peptides, prices far below market frequently signal compromised purity or underdosing.
Storage and Handling
Store lyophilized Selank at 2–8°C. Reconstituted Selank or nasal solution should be refrigerated and used within the vendor's stated stability window.
Red Flags to Avoid
Avoid missing COAs, undocumented purity claims, vague sourcing, and human-use claims. Selank's approved anxiolytic status in Russia does not equal FDA approval; research-grade material is for laboratory use only.
