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.
As men and women get older, they naturally start producing less Human Growth Hormone (HGH). So levels of IGF-1 also decline with age. The liver produces IGF-1 when HGH is released. HGH is converted to IGF-1. Aside from someone’s age, IGF-1 levels will vary depending on a person’s sex (men generally have more), level of activity, their diet, genetics and lifestyle.
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.
All groups experienced a significant improvement in strength. But the deer antler powder group showed the greatest increase in isokinetic knee extensor strength and endurance. However, it’s possible that this was due to exercise program rather than using the deer antler powder. None of the men in any group showed evidence of endocrine, red cell mass or VO2max changes. Therefore, researchers concluded that the “findings do not support an erythropoetic or aerobic ergogenic effect of deer antler velvet.” (12) On the other hand, this was a small study, with only 12-13 men in each group. This means that further testing is needed to confirm the validity of the results.
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.
Finding the time to workout is often the biggest challenge that I have, which I’m sure a lot of you can relate to. Some weeks it’s easier to find the time than others. The problem with that is on those weeks it’s nearly impossibly to find that time, my body tends to lose what I’ve gained in the weeks that I do find the time. But that’s changed recently since I’ve started using this new supplement. It’s called IGF-1 Plus™ Formula. Since I’ve been taking IGF-1, it has been quite evident that its had a positive effect on my exercising. I feel strength and stamina that I’ve never felt before. Also my pump seems to be more phenomenal than ever! My strength has steadily increased over the six months that I’ve been spraying this under my tongue as directed daily. What’s been extremely impressive is those weeks in which I come back when I’ve been unable to workout for a week or more. I simply don’t lose what I’ve accomplished like I had before. It was almost like starting back at square on before I started using IGF-1, but now it’s like I can pick up right where I left off before! Another thing that I’d like to mention about this formula is that I feel it’s really helped my memory and my stress level. That’s a welcomed added bonus which I hadn’t counted on. Just to put this all in terms anyone can understand, let me say this… I would take this IGF-1 for simply the results I’ve been able to achieve and maintain in the gym. But add to that how it’s helped my mind, memory, and stress level, I can honestly say that you couldn’t pay me to stop taking it!!
For women, deer antler velvet can help ease the symptoms associated with pre-menstruation by relieving cramps, suppressing mood swings, and raising energy levels. It is also used to treat vaginal discharges, uterine bleeding, menstrual disorders, infertility, and menopause. Russian researchers claim that compounds found in deer antler velvet can ease the effects of menopause in women.
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 Asia, velvet antler is dried and sold as slices, or as a powder which may be boiled in water, usually with other herbs and ingredients, and consumed as a medicinal soup. In the traditional commercial trade of Korea and China, whole stick antler velvet is divided into three sections based upon their supposed properties. Although there is an absence of uniform standardization, these sections are known as the wax piece (uppers or tips), the blood piece (middles), and the bone piece (bottoms): the wax piece may be marketed as a growth tonic for children, the blood piece supposedly for joint and bone health, and the bone piece supposedly for calcium deficiency and geriatric needs. Early commercial activity in Russia between the 1930s and 1980s led to the production of an alcohol extract from deer antler velvet marketed under the Russian drug trade name Pantocrin (also pantocrine or pantokrin).
