Optimum Sports Nutrition by Dr. Michael Colgan details a method of maximizing anabolic drive, that is based on 'total nutrition,' plenty of sleep, extensive training, eating six meals a day to maintain insulin levels etc. And one other key thing: supplementation, on an empty stomach 3 hours distant from protein so as to minimize competition in crossing the blood-brain barrier, with L-Arginine HCL and Ornithine AKG before training twice daily, and once before sleep, to supposedly elevate growth hormone levels. This coupled with stable insulin and all the above protocols, he argues, is what gives a real anabolic edge and can in the long term, "beat steroids." He cites a load of research, much of which he admits is controversial and based on intravenous administration. He then cites his own research in support of this regimen, based on oral supplementation. The book is old, but I have contacted the Colgan Institute, and they still swear by it. (http://www.colganinstitute.com/) I have also come across research on the internet that seems to indicate oral Arginine and Ornithine actually suppress GH by as much as 20% I've also read that Tryptophan, now made legal again, taken before bedtime, can really elevate your GH levels. Lyle McDonald in UD2.0 suggests glutamine pre-bedtime to elevate GH levels, but he is unsure as to whether it will really help. Somebody help! Whats going on here? What do you guys think, Bryan, Dan, Aaron, etc? If nothing else, I find it very interesting that Colgan does not SELL aminos. So at least he actually believes what he is doing, as opposed to some (ahem: Dr. DiPasquale) who despite being MD's sell snake oil unabashedly. But he does sell "research grade" vitamins and minerals!
