Cortagen vs HLDF-6

Vascular-targeted peptide complex that modulates endothelial cell gene expression. May support nitric oxide production, reduce vascular inflammation, and improve endothelial function.

A short peptide bioregulator derived from blood vessel tissue, developed by the Khavinson Institute. Studied for cardiovascular function support and mitigation of age-related vascular deterioration.

Modulates cholinergic neurotransmission. Reduces amyloid-β toxicity and protects against oxidative stress-induced neuronal damage. May enhance memory consolidation via acetylcholine pathway upregulation.

A hexapeptide fragment of Human Leukemia Differentiation Factor with neuroprotective and memory-enhancing properties identified primarily in Russian academic research. Studied for cognitive decline associated with aging and Alzheimer's-like pathology.
