When our competition was checked on the quality fo their OKG, most companies did not use 100% L-Ornithine Alpha-Ketoglutarate, which is OKG and what is used in Advanced OKG 5000. What they did use was Ornithine hydrochloride mixed with Alpha-Ketoglutarate powder, which is not OKG, is less expensive, less effective and does not behave like OKG in the human body. Just as important, none had AAT™. OKG is quite a remarkable and amazing nutrient. It is strongly involved in the anabolic process. It is also and anti-catabolic nutrient, aids the energy generating process and is involved in the ammonia detoxifying process (ammonia causes muscle fatigue). There is an overwhelming amount of research and technical literature which strongly indicates the values of OKG. While OKG taken by itself can be beneficial, now Advanced OKG 5000 with AAT™ is a step above all other supplements.
