I discovered arginine, ornithine and choline as a young athlete in the 1970s. I didn't really know what amino acids were and all I could read I found was in muscle magazines. I think the term "nitric oxide" is popular now. I was amazed that after a week of my body adjusting to taking it, I was able to lift more, improve my endurance and work out longer with less fatigue, and I only took it for half an hour before my workout. This worked fine for me. Didn't know if we had powders back then so intake was in pills (not food so your body can only digest amino acids). The pills contained very few milligrams, so you had to take them multiple times to get 1 gram. The life extension powder gives me 3 grams with just one level scoop. Although my workouts were a lot more relaxed, I love the fact that I don't have to take pills. My sons have benefited from my experience and I have seen their results. Many thanks to Life Extension for your amino acid powder.
