The CoA matched what I independently verified in my own assay. That's not something I've been able to say about most suppliers.

I switched to Woosh after a competitor's purity claim didn't hold up to third-party testing.

Research Profile
This peptide has been the subject of extensive preclinical investigation across multiple biological systems.
Key areas of research interest include the following.
Modulates GABAergic tone indirectly and alters enkephalin degradation by inhibiting enkephalinase. Rodent elevated-plus-maze and open-field studies show anxiolytic effect without sedation across a 100–500 μg/kg range.
Upregulates BDNF in hippocampal tissue and improves performance on passive-avoidance and water-maze tasks. Commonly studied under stress-impaired learning conditions.
Derived from tuftsin, Selank retains immunomodulatory properties — upregulates IL-6 and IFN-γ in challenged tissue, used in Russian clinical literature alongside anxiety research.
Intranasal administration is the most frequently studied route; bioavailability is acceptable across nasal mucosa. Subcutaneous delivery is also used in rodent work.
Verified Before it Reaches You.
Every Woosh batch undergoes independent third-party testing. The CoA for this product is batch-specific — issued by the testing laboratory, not generated by Woosh.
