Other studies reported an increase in heart strength and volume of blood pumped, while cardiac output, heart rate, mean arterial pressure, pulse pressure, central venous pressure and other parameters remained unchanged. Researchers suggest that the polysaccharides in antler may reduce the blood’s tendency to clot, improving circulation, decreasing stroke risk and boosting general cardiovascular health. Researchers theorize that the deer antler velvet may improve blood supply to muscles or act as an anti-inflammatory, allowing athletes to recover faster from training sessions.
Russian bodybuilders have claimed to benefit from deer antler velvet by increasing muscle and nerve strength in the late 1960’s. Earlier studies found similar results in laboratory animals and athletes given pantocrin, an extract of deer antler velvet. Several studies show a positive correlation between consistent use of deer antler velvet and cardiovascular health. Human subjects who used deer antler velvet were able to endure larger work loads and experienced a shorter recovery time between exercises.
Assuming that deer antler velvet is the next biggest thing in muscle building and athletics isn’t just a massive leap of faith, it’s something that can’t be supported by science in any way, shape, or form. So why is it illegal? Because it’s still a synthetic, man-made growth hormone precursor. Those are illegal, according to most professional sports.

For a long time velvet antler is recognized as a powerful tonic that naturally stimulates us with a clean and non-fatiguing energy. Not like coffee or energy drinks. This effect can be subtle, but its long term consumption benefits are profound in that we can more easily overcome and adapt to daily stress. Many types of stress depending on who we are as individuals. How much to take is important and talked about in the dosage section. Having the capability of increased resistance to physical stress is a major use to everyone. 

First, the following disclaimer: Products that are sold as supplements (as opposed to medications) are not regulated by the Food and Drug Administration so they are not tested for safety, efficacy or standardization.  In other words, when you buy a supplement, there is no guarantee that what is in the bottle has been tested to see if it even contains the ingredient in question, let alone whether the ingredient actually does what it claims to.  (That’s not a value judgment, just the facts.)
In a randomized, placebo controlled test in 2004, researchers at the University of Alberta, Canada, placed 18 males from the Edmonton Police Force into a 9 week strength training program. The results showed that deer antler velvet increased the strength and endurance of the subjects relative to the control group. The researchers found that use of deer antler velvet significantly increased blood plasma testosterone levels.
