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.)
When antlers fall off, they leave wounds that heal quickly, without forming a scar. Researchers have found that velvet antler contains substances that encourage healing, and could be of use to humans. Of particular interest are 3 hormones known to promote growth of skin tissue: insulin-like growth factor (IGF-1), epidermal growth factor (EGF) and transforming growth factor-β1 (TGF-β1). In a recent study, an ointment made from velvet antler, containing these compounds, enhanced healing when applied to the skin of rats. IGF-1 was a hot topic in the media in the winter of 2013 when a football player, Ray Lewis, was accused of using a banned spray containing IGF-1.
As this supplement is derived from 'deer', the two most commonly used species of deer in mainland China include the Sika deer Cervus nippon Temminck and Red Deer Cervus elaphus Linnaeus; these species may be relevant. 'Farming' of deers for antlers includes raising deer and sawing off the antlers under analgesia, the annual yeild appears to be 120-150 tonnes and deer are not usually killed as antlers are capable of full regeneration.
These are required in enzyme and catalytic cellular functions as well as being the raw material for tissues. Growth factors are known to boost cellular functioning and uptake of nutrients This helps our own growth, regeneration of tissues and injury recovery, as well as a slowing and preventing the effects of agings. Many hormones are closely associated with IGF-1
IGF-1 is currently on the World Anti-Doping Agency’s prohibited list due to how it gives athletes an unfair advantage in terms of building strength and muscle mass. (7) However, it’s still legal to use supplements that may provide IGF-1 or similar effects. Most of the studies that show positive results from using deer antler supplements have used high doses. And some have tested the product on animals (mice or rats) rather than humans.
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.
Shake well before use. As a dietary supplement, spray 2 times under tongue, 3 times per day. Hold the liquid under your tongue without swallowing for 20 seconds. This allows the formula to penetrate through your endocrine glands. Then the active molecules are then released directly into your bloodstream. This is how Nutronics Labs' liposome technology is able to deliver an enhanced bioavailability! Caution: Do not use if outer seal is broken. Not intended for individuals under the age of 18. Consult your health care provider prior to use if you are pregnant or nursing, have a medical condition, or when taking any medication.
Deer antler velvet may help to increase macrophage activity. Macrophages are a type of white blood cell (immunity cell) that digests cellular debris, foreign substances, cancer cells, and other microorganisms. Macrophages help to stimulate defense mechanisms in the body by recruiting immune cells such as lymphocytes. With this increased number of white blood cells, your immunity system becomes strengthened and will have a better chance at fighting off a sickness or infection.
"I have been real happy with the results. My lifting has definitely increased alot. I've gotten alot stronger. My endurance is amazing too. It's kind of had a domino effect on my workouts and my health overall. I've added almost 10 lbs. of muscle, which has been great. If you are looking for a good product to take, I highly recommend the one I came across and the one I have been using, Antler Farms®."*
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 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.
