All groups experienced a significant improvement in strength. But the deer antler powder group showed the greatest increase in isokinetic knee extensor strength and endurance. However, it’s possible that this was due to exercise program rather than using the deer antler powder. None of the men in any group showed evidence of endocrine, red cell mass or VO2max changes. Therefore, researchers concluded that the “findings do not support an erythropoetic or aerobic ergogenic effect of deer antler velvet.” (12) On the other hand, this was a small study, with only 12-13 men in each group. This means that further testing is needed to confirm the validity of the results.

Research has been conducted on the potential use of deer antler velvet for healing of wounds. In Russia (Arapov, 1969), Pantocrin was administered to patients with surgical and internal wounds. The study reported that there were a number of positive effects, including the normalization of arterial pressure, reduction in surgical complications, and becoming active quicker. In tests on rats (Wang, 1985), bone fracture repair was accelerated. A recent study by Bubenik found that antler helped heal epidermal wounds in rats. In another study by Takikawa, et al., researchers reported observing new bone formation following experimental whiplash injuries in rabbits. Pretreatment in rats reduced cell degradation and improved recovery times from extreme temperature and electric shock exposure. 
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.
