Prostamax vs Dihexa

Side-by-side comparison of key properties, dosing, and research.

Anti-Aging & Longevity
Prostamax
Cognitive Enhancement
Dihexa
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.
Dihexa is a potent experimental oligopeptide derived from angiotensin IV that dramatically enhances synaptogenesis. Preclinical research shows cognitive enhancement orders of magnitude more potent than BDNF — it is considered one of the most powerful nootropic compounds in research, but has very limited human safety data.

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
  • Anti-aging effects on prostate glandular tissue
  • Complementary to conventional BPH therapies
  • Dramatically increases synapse formation (potentially 10 million× more potent than BDNF in animal models)
  • Enhances memory and learning
  • May reverse cognitive decline
  • Improves neuroplasticity and executive function
  • Long-lasting cognitive benefits from short courses
  • Potential therapeutic agent for Alzheimer's
Side Effects
  • Generally well tolerated in available research
  • Mild injection site reactions
  • No significant adverse urological events reported at standard doses
  • Headache
  • Irritability
  • Brain fog during washout period
  • Unknown long-term effects (insufficient data)
