How It Works

How It Works: Testagen functions as a bioregulator peptide that interacts with DNA in testicular cells, modulating gene expression to restore normal hormone production and reproductive functions.

  • Upregulates genes involved in testosterone synthesis and secretion.
  • Enhances spermatogenesis and sperm quality.
  • Protects testicular cells from age-related damage and oxidative stress.
  • Normalizes hormonal balance in the hypothalamic-pituitary-gonadal axis.

The Inhibitory Effect and Adsorption Properties of Testagen Peptide on Copper Surfaces in Saline Environments: An Experimental and Computational Study.

This study looks at a tiny protein fragment called testagen (KEDG) and how well it sticks to copper in salty water to stop the metal from rusting. It’s a chemistry/engineering experiment, not a health or performance supplement, so it doesn’t give any direct advice for body optimization.
