In an ovalbumin sensitized mouse model, 4 weeks of Velvet Antler at 2.5-10mg total (weight of mice not given, assuming 20g this equals 125-500mg/kg or 10-40mg/kg for humans) was able to reduce total Immunoglobulin E (IgE) and Ovalbumin-specific IgE at 14, 21, and 28 days.[21] When challenged with methacholine and subsequently having their airway power measured, it appeared that Velvet Antler exert anti-asthmatic effects in regards to allergies.[21] 

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.

Being a former collegiate athlete, I’m no stranger to working out. When a former teammate of mine started talking about this new, state of the art, health product and the effects he was getting from it, it peaked my interest needless to say. I remember him continually saying that I’d have to try it to believe what it does for you. Wow, I must now say that I know what he means (and then some)! First of all, this IGF-1 Plus™ Formula did have some impressive results for me in my workouts. It’s not only helped my strength, but it seems that I especially notice a difference in my joints and my recovery time. Since I lift with heavy weights, my joints used to ache after working out, but they no longer do! My endurance also has really improved as well. I’ve actually doubled the time and distance that I was doing before (and I’ve only been on it for a little over a month)! An unexpected (but much welcomed) improvement that has been incredible is in how clearly I’ve been able to think and I feel very little stress anymore. It almost like someone put a micro-computer chip in my brain that makes it work much more efficiently without trying nearly as hard. It’s one of those things that you have to try to really believe it (trust me, it has done much more than I expected it to). I look forward to turning a friend of mine on to it, since he’s a personal trainer and trains professional athletes! Thanks, Dr. Duarte. I plan to use your IGF-1 Plus™ from now on, and will stock up so I don’t run out!

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.

Supplements are best used in situations where an individual is unable to get their nutrients from their diet. Perhaps an individual has an allergy or intolerance, for example lactose. They are unable to consume milk products which in turn limits their ability to get sufficient calcium and vitamin D from their diet. In that case, a supplement makes sense.
And is easily understood as increasing the state of health, well-being and performance of body, mind and spirit. We see that its been known by many names. More recently in the Western world, a liquid form, sometimes known as deer antler spray, has become popular within North American for its specific cellular and glandular benefits. But what's all this buzz and hype?

Velvet antler has been used in traditional Chinese medicine (TCM) that classifies many similar substances from a variety of species under the simplified Chinese name 鹿茸; (pinyin Lu Rong) and the commercial name Cervi Cornu Pantorichum.[citation needed] The two common species used within the TCM system are sika deer and red deer which are thought to be useful for treating yang deficiency syndromes.[6][7][8]
A study (Yudin and Dobyrakov, 1974) on the effect of deer antler velvet extract on the static load-bearing capacity of subjects found that those who took the extract increased the time of work by 2-4 seconds compared to the control group. In tests of dynamic work using a veloergometer, the subjects who took the extract increased the work output 4 to 5 times more than the control group.
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.
