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]
Mental Capacity and Alertness: If you’re tired of feeling like you’re experiencing life through a fog, Deer Antler Velvet can help fade the fog and give you the clarity of a good night’s sleep combined with a week’s vacation. You come at things sharp and focused. Instead of struggling to remember things words, decisions, insights and just your general alertness are sharpened.
Currently, one study that induced a fracture unto a rat bone and injected 20mg/kg of Velvet Antler polypeptides into the area every other day for 7 weeks noted that fracture healing rate was dose-dependently increased at weeks 4-7 relative to control and that the bone loading weight was increased following rehabilitation with 10mg/kg (60.7%) and 20mg/kg (93% more than control) after 7 weeks.[29] An in vitro study suggested that this was due to a concentration-dependent mitogenic activity on osteoblastic precursors and chondrocytes.[29]
In an ovalbumin sensitized mouse model, 4 weeks of Velvet Antler at 2.5-10mg total (weight of mice not given, assuming 20g this equals 125-500mg/kg or 10-40mg/kg for humans) was able to reduce total Immunoglobulin E (IgE) and Ovalbumin-specific IgE at 14, 21, and 28 days.[21] When challenged with methacholine and subsequently having their airway power measured, it appeared that Velvet Antler exert anti-asthmatic effects in regards to allergies.[21] 
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.
