More recent tests (Slievert, 2003) confirm deer antler velvet’s effects on muscle strength and endurance. In a randomized, double blind, placebo controlled experiment, 18 males entered a 10 week strength training program. Those who took deer antler velvet showed an increase in maximal aerobic capacity, an increase in strength in the bench press and leg squat, and decrease in body fat relative to the placebo group.
On January 30, 2013, Vijay Singh professional PGA Tour golfer was caught unaware and openly admitted to the personal use of deer antler spray which contained a banned substance at the time. A week later the World Anti-Doping Agency (WADA) lifted the ban on deer antler spray, but with urgency, "Deer Antler Velvet Spray may contain IGF-1 and WADA recommends therefore that athletes be extremely vigilant with this supplement because it could lead to a positive test."  The consensus opinion of leading endocrinologists concerning any purported claims and benefits "is simply that there is far too little of the substance in even the purest forms of the spray to make any difference,"  and "there is no medically valid way to deliver IGF-1 orally or in a spray."

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. When challenged with methacholine and subsequently having their airway power measured, it appeared that Velvet Antler exert anti-asthmatic effects in regards to allergies.
