Prostamax vs PE-22-28
Side-by-side comparison of key properties, dosing, and research.
- Summary
- 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.
- PE-22-28 is a synthetic analog of spadin derived from sortilin, designed to block TREK-1 potassium channels with rapid-onset antidepressant and neurogenic effects. It shows fast-acting depression relief (within 24 hours) and promotes hippocampal neurogenesis.
- Half-Life
- Short (minutes); sustained gene-regulatory effects
- Relatively short; CNS effects may persist due to neurogenic mechanisms
- Admin Route
- SubQ, Oral
- SubQ, Intranasal

- Key Benefits
- Supports normalization of prostate tissue architecture
- May reduce prostate enlargement associated with BPH
- Anti-inflammatory effects on prostatic tissue
- Reduces prostate cell apoptosis from oxidative stress
- Potential support in chronic prostatitis
