Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

Prostamax is a short synthetic peptide, reported as the tetrapeptide Lys-Glu-Asp-Pro, developed in Russia as one of the so-called Khavinson bioregulator peptides. It is described as being modeled on peptides from prostate tissue and is proposed to influence gene expression and chromatin in aging cells, though this mechanism is not well established.

What the evidence shows

Automatic summaryAnimal / preclinical

There are no registered human trials, and the roughly five published papers are mostly cell and animal studies from a small group of researchers. Any benefit for prostate health or aging in humans is unproven.
