Prostamax vs GHRP-2

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

Anti-Aging & Longevity
Prostamax
Growth Hormone Peptides
GHRP-2
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.
GHRP-2 is a potent synthetic hexapeptide that stimulates growth hormone release by activating ghrelin receptors in the pituitary and hypothalamus. It produces one of the strongest GH pulses among GHRPs, though unlike Ipamorelin it does cause modest increases in cortisol and prolactin.
