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.)

It is difficult to analyze the quality of Deer Antler Velvet Spray’s ingredients due to their largely untested nature.

One study[14] (duplicated in Medline[15]) that used a water extract of Velvet Antler at 50-200mg/kg failed to inhibit the pain killing effect of Morphine yet reduced the rate at which rats became tolerant to Morphine over the course of 6 days when taken an hour prior to Morphine each day.[14] Rats who were given Velvet Antler prior to Morphine also experienced 26.6-36.6% less withdrawal (dose-dependent) and reduced reverse tolerance and dopamine receptor supersensitivity relative to morphine control.[14]


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.
