This proprietary, patent-pending effervescent formula is designed to provide a safe and effective means of naturally elevating GH and IGF-1 levels. GH Stak is the only growth hormone releasing peptide (GHRP) formula available that protects the delicate precursors, improves absorption, increases receptor activity and suppresses the anti-hGH regulator metabolite somatostatin. Research indicates that this GHRP technology may be even more effective than synthetic GH injections. That explains why this product has become the most sought after GHRP on the market, based on volume, statistics and consumer comments.
