One double-blind study published in the International Journal of Sports Nutrition and Exercise Metabolism tested whether or not deer antler velvet powder or extract had an impact on aerobic performance, endurance and “trainability of muscular strength” compared to a placebo. The subjects were adult males. They were given either a placebo, or deer antler extract or powder supplementation over a  10-week period while undergoing a strength-building routine. The men were measured for muscular strength, endurance, and VO2max before and after using deer antler. These results were determined by measuring circulating levels of testosterone, insulin-like growth factor, erythropoietin, red cell mass, plasma volume, and total blood volume.
One study in men given 1.5g Velvet Antler for 11 weeks noted that intake of Velvet Antler was associated with a greater improvement in peak torque (30+/-21% more than baseline vs. placebo increasing 13+/-15%) and average power (21+/-19% vs. 7+/-12%) as assessed by leg extension; the authors noted that other parameters suggestive of power improvement (such as endocrine improvements or erythropoesis) did not occur and noted that replication is needed.[26] The lack of aerobic improvement noted in this study is contrasted by another study using 2,700mg of Velvet Antler (two doses of 1,350mg daily for 10 weeks) which improved VO2 max by 9.8%, although this study had a remarkably high dropout rate of 44% which precludes conclusions that can be drawn.[27]

Dr. Low Dog also reports that a chronic wasting disease in deer, elk and moose is the only recognized prion (infectious protein) disease of wild animals and has been found in 15 states and two provinces in Canada. (Prion diseases in wild animals are similar to bovine spongiform encephalopathy, better known as mad cow disease, in cattle.) No known cases of neurological disease have been seen in humans who have taken deer antler velvet supplements, but a 2009 study sponsored by the National Institutes of Neurological Diseases and Stroke and the U.S. Department of Agriculture concluded that the possibility remains.

From cave people to you and me. Deer antler is easily consumed as a nutritional source for over 2000 years of recorded history, and no doubt long prior to the written word. Old school energy for modern stress. Used as a trophy from hunters, deer antler has been used as a superfood high in unique protein that will strengthen tissues and increase resistance to physical stress. Later, you'll see more about how that has become science today.
L-Arginine: An amino acid usually found in red meats that is important for the body’s ability to manufacture proteins. L-Arginine has been used to treat conditions like high blood pressure, congestive heart failure, blocked arteries, and erectile dysfunction. L-Arginine is safe for most people, however it should not be taken by women that are pregnant or breastfeeding.
