What Is Tirzepatide (Mounjaro/Zepbound) & How Does It Work?

Tirzepatide is a synthetic 39–amino acid peptide that acts as a dual GIP and GLP-1 receptor agonist[1]. In other words, it mimics two natural incretin hormones (GIP and GLP-1) to enhance insulin secre

What Is Vesugen? The Vascular Bioregulator Peptide Explained

Vesugen—also written Vezugen and standardized here as KED for its sequence Lys–Glu–Asp—is a synthetic tripeptide “bioregulator” studied for vascular endothelium and neuroplasticity outcomes in preclinical models. It appears to act via epigenetic regulation of gene expression (DNA/histone interactions) with downstream effects reported for endothelin‑1 (EDN1), connexins (e.g., GJA1/Cx43), and SIRT1 in vascular cells, and markers…
