Almost every preworkout over the last 15 years have contained some form of Arginine.It was the original vasodilator and was in every "NO" product. We now have much better options for a pump. The researchers in the study found something that should confirm to supplement companies that Arginine shouldn't be used in preworkouts anymore. Trained athletes who ingested 6g of Argininebefore working out had a 41% decrease in GH and IGF-1 levels postworkout. Yourbbody naturally releases GH and other growth factors after a workout to help repair and rebuild muscle tissue. Taking Arginine before a workout may significantly hinder your body's natural anabolic response to training! With somany better options for pumps, including citrulline malate and my favorite,organic nitrates, arginine is outdated. In fact, citrulline has been shown toraise arginine(and thus NO) plasma levels greater than arginine.
