Semax vs Prostamax
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Semax is a synthetic heptapeptide derived from ACTH developed in Russia. It is a potent nootropic that enhances memory, focus, and provides neuroprotection. Approved in Russia for cognitive disorders, stroke recovery, and traumatic brain injury.
- 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.
