Deer antler velvet has been used in China for over 2,000 years. More recently, Soviet scientists in the 1980s tested the effects of deer antler velvet on the performance of elite Russian athletes, and the results were astonishing. Deer antler velvet helped increase the strength and muscle mass of Russian athletes, and speed their recovery time from exercise.
A systemic review on human interventions makes note of a study conducted on patients of osteoarthritis (Edelman et al. 2000; cannot be located online) which found improvements in joint pain symptoms relative to baseline in the Velvet Antler group and not placebo, although a lack of information on blinding and randomization precludes results that can be drawn from this study.
