THE IMMUNE BALANCER
Glu-Asp-Pro Peptide
Crystagen is a synthetic three-amino-acid peptide (Glu-Asp-Pro) designed to regulate immune function. It works by entering immune cells and modifying gene expression to enhance T-cell activity while reducing excessive inflammation. It's particularly useful for aging individuals whose immune systems have declined.
