It is recently gaining popularity in the USA as seen with the deer antler spray controversy a couple years ago concerning several professional athletes. Oh yeah, I heard its a performance enhancer. They were consuming it for its natural growth factors, extracted via cold water, which are known to promote growth and regeneration capacities. Natural? Yes, and healthy. Where does this stuff come from?
Deer antler velvet is rich in insulin-like growth factor 1 (IGF-1) which is a growth hormone produced naturally in the liver as a response to human growth hormone (HGH) stimulation. This is a key factor in how deer antler velvet can help to promote muscle growth. IGF-1 works on the body by promoting the growth of healthy, lean skeletal muscles. This growth of healthy muscle mass can be influenced by IGF-1's tendency to increase muscle protein and muscle DNA content. There is evidence to suggest that IGF-1 acts on muscle tissue by promoting protein synthesis and the proliferation of satellite cells, both of which result in skeletal muscle growth due to the enlargement of the muscle cells.

1g of Velvet Antler taken daily for 12 weeks in otherwise healthy adult men has failed to significantly alter serum testosterone levels, either total or free testosterone.[8] Another study in otherwise healthy men has also failed to find such an effect on the endocrine profile, with 11 weeks of 1.5g supplementation failing to alter serum testosterone[26] and a lack of effects also noted after 10 weeks of 560mg in males and females who performed a consistent rowing regimen.[28]
Although previously found on the World Anti-Doping Agency's list of banned substances, Deer Antler Spray was removed in 2013 when it was deemed completely safe and legal to consume prior to athletic activity. Deer Antler Spray has been known to speed up the rehabilitation process of injuries, especially injuries effecting cartilage. It has also been known to boost endurance and strength, increase muscle mass, decrease fat, and raise one's testosterone levels, thus increasing libido. The use of Deer Antler Velvet Spray has been linked to several athletes, including football star Ray Lewis, who is rumored to have used it following an injury to his tricep in 2013.

Many people from many cultures use it. Throughout history it has been used by the American Indians, Europeans, Romans, Russians, and Asians as an alcohol extract. Often it was easily made into soups for its strengthening bone broth protein full of raw material for tissues, joints and bone. The most complete ancient literature is the Chinese texts, which give it top classification for over 2,000 years.
Some people use deer velvet to increase levels of certain sex hormones (estrogen and testosterone), improve fertility, increase interest in sexual activity (as an aphrodisiac), and treat male sexual performance problems (erectile dysfunction, ED). Women use deer velvet to reduce the dose of estrogen they need in hormone replacement therapy. They also use it for menstrual and menopause problems, vaginal discharges, and uterine bleeding.
We know about growth factors, such as IGF-1, which are responsible for promoting healthy hormones. It is the synergy of all the constituents that help these growth factors work better. And this is why our deer antler velvet is so awesome! If you go read other labels and check the magic "extract-ratios" and micro-nanogram amounts, you'll discover something interesting:
Adaptogen: Adaptogens are natural metabolic regulators that increase a person’s ability to adapt to environmental factors-like pollution, smoke, stress, toxins etc. and to avoid damage from those factors. In other words, adaptogens literally help your body “adapt” to the environment without any side effects. If you’re living in the real world, with external or internal stressors, adaptogens help your body change in order to cope with the stressors.
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.)

My name is William Gucciardo. I am fifty-four years old and have been exercising and taking nutritional supplementation for many years. I was recently introduced to IGF-1, and have been taking it for three weeks. Although I have been working out six days a week for the past several years, I have recently noticed an increase in upper body muscle tone and overall strength and endurance. I have also noticed that minor stiffness that I daily experienced upon arising in the morning is gone. My body feels stronger with an overall feeling of well being. I can only attribute these changes to the addition of IGF-1 to my supplementation program, as this is the only change that I have recently made. I do not know what further benefits I will receive from taking IGF-1 daily. If you are willing to try something new with the possibility of improving your health and well being, I would recommend trying this product.
Published research has shown that IGF-1 can produce similar results to growth hormone. The catch? If you do the math from the study, a 150-pound man (that’s a pretty small guy, so a bigger man would need more) would have to take more than 25 million nanograms just to experience the growth hormone-like effects of more muscle, less fat, and faster recovery.
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.
