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.[28] 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.[27]
A systemic review on human interventions[25] 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.
