Study aims to confirm amino acid supplementation increases growth hormone and IGF-1

Growth hormone (GH) and insulin-like growth factor-1 (IGF-1) are critical regulators of growth, metabolism, and tissue repair. Maintaining optimal levels is important for various physiological functions. While recombinant GH and synthetic growth hormone-releasing peptides (GHRPs) are used clinically and sometimes illicitly in sports, there's ongoing interest in natural or supplemental approaches to modulate these hormones. Amino acids, as fundamental building blocks and signaling molecules, are explored for their potential to stimulate endogenous GH and IGF-1 production, offering a potentially safer or more accessible alternative.

This study aimed to replicate and confirm findings from a previous investigation. The protocol involved administering a single low-dose of a supplement containing two unspecified amino acids in pill form. The primary objective was to assess their impact on growth hormone and insulin-like growth factor-1 levels. Specific details regarding the study model (e.g., human, animal), sample size, exact amino acid composition, precise dosage, administration route, duration, or control group design were not provided in the abstract.

The provided abstract explicitly states the purpose of the study: "to confirm the results of a prior study that demonstrated pills containing two amino acids which are in foods increased growth hormone and insulin-like growth factor-1." However, the abstract does not present any results or findings from the current study itself. Therefore, no specific data, statistical outcomes, or quantitative changes in growth hormone or IGF-1 levels from this particular investigation can be reported. The abstract does not indicate whether the study successfully confirmed the prior findings or if any other outcomes were observed.
