The GH Stack is a unique, secretagogue formula, which can work with your body to support levels of human growth hormone. GH Stack may help signal your pituitary gland to release more h GH through its unique formulation of L-dopa, 5-HTP, & Somatopro ATM, a complex consisting of key amino acid secretagogues in scientifically-suggested ratios. First & foremost, there´s L-dopa (levodopa), a metabolic precursor to dopamine. Unlike amino acid secretagogues, L-dopa can enhance h GH release through an entirely different mechanism. In this way, L-dopa can work alongside Somatopro ATM to support overall effects. The proprietary ingredients found in GH Stack are absorbed rapidly & assimilated efficiently. The secretatgogues are released gradually, for a sustained GH support.
