Currently, IGF-1 is banned by both the World Anti-Doping Agency and the Food and Drug Administration (FDA). However, deer antler spray seems to provide only very small amounts of IGF-1. This is why it’s no longer considered illegal. Insulin-like growth factor is also naturally found in other animal-derived foods, including eggs, milk and red meat. Some experts believe that the amount of IGF-1 obtained from using deer antler products is really not much more than from eating these foods.
A study conducted in rowers given 560mg Velvet Root for 10 weeks of training has failed to find improvements in rowing performance or other parameters of strength (bench press and leg press) in both sexes. 1350mg of Velvet Antler twice daily (daily dose of 2,700mg) for 10 weeks was noted to increase leg strength (assessed via leg press) more than placebo with no differences in the bench press; this study had a 44% dropout rate and conclusions that can be drawn are limited.
Deer antler velvet can play a pivotal role in helping to not only relieve the symptoms of diseases that affect joints, such as osteoarthritis, they can possibly eliminate them entirely. The way it may do this is through the introduction of chondroitin sulfate and glucosamine sulfate into the body. Both of these compounds are abundant in deer antler velvet.
