GHB based supplements were actually forced off the shelves of natural food stores years ago. However, Renewtrient and products like it did not have GHB, but ingredients like GBL and BD that are not GHB, but are nonetheless still illegal, because they turn into GHB after entering the system. They claimed it would fight stress and depression, stimulate HGH, induce deep sleep, relieve anxiety, aid in muscle building, enhance athletic performance, and combat aging. But the benefits are not as sure as the consequences are. At least one death has been attributed to the specific use of Renewtrient. Therefore, it would be extremely inadvisable to go looking for this product or anything like it.
