Ventfort

A Khavinson-line 'cytomax' supplement made from a peptide complex extracted from calf blood vessel tissue, sold under the code A-3 and marketed for vascular and circulatory support. The proposed mechanism is that short tissue-derived peptides act selectively on vascular wall cells, entering cells and binding DNA to restore a more normal pattern of gene expression in endothelial and smooth muscle cells. No specific receptor, binding affinity, or signaling cascade has been characterized. Evidence base is thin with no registered, randomized, placebo-controlled clinical trials in humans.
