Summary
GHK is the natural tripeptide (Gly-His-Lys) released from human albumin that activates tissue remodeling, collagen synthesis, and anti-aging gene expression. The copper-free form is the biological signaling molecule; it chelates copper in tissue to form GHK-Cu but also has independent biological activity.
Prostamax is a tetrapeptide bioregulator (Lys-Glu-Asp-Pro) developed by Professor Vladimir Khavinson, tissue-specific for the prostate gland. It supports prostate epithelial cell function, promotes normalization of prostate tissue, and is studied for its potential in benign prostatic hyperplasia (BPH), prostatitis, and prostate anti-aging. It is one of the more widely used Khavinson bioregulators among men over 40.
