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

Compound arrived lyophilized, correctly labeled, with a batch-specific CoA. Exactly what a research order should look like.

Research Profile

This peptide has been the subject of extensive preclinical investigation across multiple biological systems.

Key areas of research interest include the following.

Drives thymocyte differentiation into CD4+ and CD8+ T-cells; restores T-cell populations in immunosuppressed cohorts.

Approved for chronic hepatitis B and C in 35+ countries; published oncology-adjunct data in non-small-cell lung cancer and melanoma.

Restores natural-killer-cell cytotoxicity in published immunosenescence and chronic-viral-infection models.

Subcutaneous injection, typically 1.6 mg twice weekly in clinical protocols. Plasma half-life ~2 hours is offset by prolonged downstream immune effects.

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.
