The GH Stack is a unique, "secretagogue" formula, which can work with your body to produce optimum levels of human growth hormone. GH Stack can help signal your pituitary gland to release more hGH through its unique formulation of L-dopa, 5-HTP, and Somatopro ATM, a complex consisting of key amino acid secretagogues in clinically-proven ratios. First and foremost, there´s L-dopa (levodopa), a metabolic precursor to dopamine. Available only by prescription in many countries, athletes have used L-dopa to stimulate endogenous hGH production in the body. Unlike amino acid secretagogues, L-dopa can enhance hGH release through an entirely different mechanism. In this way, L-dopa can work alongside Somatopro ATM to provide you with the best overall effects. The proprietary ingredients found in GH Stack are absorbed rapidly and assimilated efficiently. The secretatgogues are released gradually, for a sustained GH release. This effectively doubles your dose of GH-enhancing nutrients found in GH Stack. All in all, GH Stack will work more effectively and more readily than any other GH supplement out there. **This is an HGH Supplement not actual HGH.
