While consumers wanted more information on the product. Let’s not forget the supplement industry is a multi-billionaire dollar business. And if Ray used the product then it must be legit, right? That’s what the immediate response in supplement sales would have you believe, as ESPN business reporter Darren Rovel reported that purchases skyrocketed within 24 hours of the report.


Our Deer Antler Velvet comes from red deer in New Zealand, the premier location for Deer Antler Velvet. Every year, these deer are able to regrow their antlers, which are removed in the pre-calcified state, thus the term “Deer Antler Velvet”. Deer are the only mammals to regrow tissue in such a way and at such a rapid rate, making it high in the growth IGF-1. For thousands of years, these pre-calcified antlers have been used in Chinese Medicine, where they are brewed into a tea to be consumed as a cure for a myriad of ailments and conditions – with the help of our spray, you now have access to these same benefits*.
A Russian study indicated that the amino acids, polypeptides and other compounds found in antler increased the survival rate of mice with cancerous tumors as much as 40 percent. In addition, a study conducted by the East-West Research Institute in Korea found that deer antler velvet appears to increase neutrophil levels in mice, which boost the body’s ability to fight injuries and disease. The mice with tumors lost less weight and suffered lower levels of kidney damage than those treated with drugs.

Aphrodisiac* - For a long time the alcohol extract has been used to strengthen reproductive organ function, but modern studies of deer antler velvet results are inconclusive concerning women and from men. Although some people do report benefit in intimacy, this may be because of the performance, blood circulation and stress adaptation effects.* So in other words, if your supplement doesn't have the alcohol extract in it don't expect the benefits of supplements made with it.*
Chondroitin sulfate is a compound of connective tissues that are usually found in cartilage. Glucosamine sulfate is a natural building block for the growth and maintenance of healthy cartilage. Since osteoarthritis is caused by the deterioration of the cartilage in the bone joints, a daily supplement of deer antler velvet can help to stimulate the repair of deteriorated bone cartilage with healthy doses of chondroitin sulfate and glucosamine sulfate.

An acute dose of 2,000mg/kg Deer Velvet Antler to rats (human equivalent dose of 320mg/kg) has failed to show toxic signs over 14 subsequent days of observation, and a 90 day trial with daily dosing of 1,000mg/kg did not show any significant toxicological symptoms of haemotological signs; a decrease in liver weight was noted in males, but under histological examination it appeared to be benign.[38] Another rat toxicological study using 10% of the diet as Deer Velvet Antler during gestation and after birth noted that there were no apparent teratogenic effects on the rat pups and that serum AST (indicative of liver damage) was actually decreased 50% relative to control with no effect on γ-GT (another liver enzyme).[30]

This is a full spectrum extraction of one of the most profound substances in the anti-aging and longevity category. Deer Antler Essence is a premiere tonic formulation for the rejuvenation of Yin Essence, Yang Essence, and blood. Deer Antler is a prized tonic in the East that provides deep nourishment of Jing Essence. Considered a Yang tonic, it provides physical, sexual, and creative energy by nourishing the root energy of the body. It also is extremely powerful for nourishing bone marrow and building blood.


Research has been conducted on the potential use of deer antler velvet for healing of wounds. In Russia (Arapov, 1969), Pantocrin was administered to patients with surgical and internal wounds. The study reported that there were a number of positive effects, including the normalization of arterial pressure, reduction in surgical complications, and becoming active quicker. In tests on rats (Wang, 1985), bone fracture repair was accelerated. A recent study by Bubenik found that antler helped heal epidermal wounds in rats. In another study by Takikawa, et al., researchers reported observing new bone formation following experimental whiplash injuries in rabbits. Pretreatment in rats reduced cell degradation and improved recovery times from extreme temperature and electric shock exposure. 
Improved Athletic Performance: Whether you’re a professional athlete, a weekend warrior, or you just throw a ball around the front yard with your kids once in awhile, Deer Antler Velvet makes what you do better because it enhances the muscles, energy, stamina and circulation of your body. Think about the way you feel going into a sport or activity without warming up first, and how you feel after about 30 minutes or so into the activity. That smooth, loose, flowing feeling you have after you get “warmed up,” and get the blood flowing and the muscle temperature raised with activity makes a big difference in how you feel and how you play. It’s a subtle thing, but when you feel it you know it. Deer Antler Velvet does the same thing-provides a subtle, yet distinct sense that your body is ready to function at a higher level.
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.)
In rats undergoing left coronary artery ligation, those with heart failure were given either Velvet Antler (Deer) or Captopril as active control for 4 weeks with a third group given water.[17] No significant changes in cardiac structure was noted with either Velvet Antlers or Captopril (with the heart tissue being enlarged after heart failure) although left ventricular ejection fraction (LVEF) and fractional shortening (LVFS) appeared to be improved in both treatment groups to approximately the same degree and the increase in serum Brain Natiuretic Peptide (BNP) that occurred with heart failure was attenuated the same degree in both interventions.[17]
According to modern research, deer antler velvet has shown gonadotropic activity. Studies by both Fisher and Wang indicate that deer antler velvet may increase testosterone levels in men and can help prevent some conditions associated with aging. The estrogen hormone most affected by deer antler velvet is estradiol. Estradiol is a precursor to testosterone.

Immortal Antler Velvet Gold is the Mercedes of antler velvet extracts. It is the only all-natural 43:1 extract that contains a powerful blend of growth factors in a naturally occurring matrix. These naturally occurring growth factors are involved in every cellular function in the human body, from metabolism to immune response. Immortal Antler Velvet Gold is the only all-natural proprietary matrix to deliver up to 100 mcg’s of IGF-1 per bottle, in addition to the full growth factor matrix. Delivering a full range of growth factors at an alarming 43:1 ratio means there is no stronger formula on the market today. This ratio means it requires 43 lbs of velvet antler tips to create 1 lb of this complete formula. It is extracted in organic grape alcohol and bottled in miron violet glass for maximum absorption and effectiveness.
"I am 60 years old and had polio when I was six months old. Throughout my childhood I had 7 orthopedic surgeries to correct the damage leftover by polio to my left hip, leg and foot. I am battle scarred and a Post Polio Syndrome Survivor. I cannot praise your product enough! Its difficult for me to walk. I normally use a battery powered scooter in malls and airports. The least amount of physical exertion walking and standing creates days of agony afterwards. This past Saturday I walked the mall, went for a movie and dinner. I was active all day and well into the night without tiring. I kept waiting for the intense painful spasms and muscle contractions from my polio atrophied muscles in the left leg and also my hips. Usually late at night is when the pain and spasms are the most intense. But guess what? I am not hurting anywhere near the level I use too. I am not fatigued. I used Antler Farm's Deer Antler Velvet a couple of years ago when traveling to Machu Picchu, Peru. I am still amazed I climbed the ancient Inca Trail unaided with just my cane. Antler Farm's Deer Antler Velvet has improved my quality of life significantly."*

In Chinese medicine, deer velvet has been used to treat impotence, female disorders, urinary problems, skin ailments, and knee weakness. It is also employed as a tonic in children with learning disabilities or insufficient growth.16 Koreans use antler velvet to treat anemia and impotence and to stimulate the immune system, treat impotence, improve heart function, muscle tone, lung efficiency, and nerve function.17


Deer antler velvet can act as a natural adaptogen, restoring homeostasis to an unbalanced body by helping where it is needed. Deer antler velvet has an effect on many systems of the body given its complex chemical composition. The active ingredients in deer antler velvet are mostly precursors that are required by the body to process substances that maintain its health and wellbeing.
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.

Even more intriguing is how the stags manage to regrow their antlers. Scientists have found stem cells at the bases of antlers’essentially ‘blank’ cells that can develop into many different types of cell, such as a skin cell or a cartilage cell. If they could find out what triggers the stem cells and controls their development into antlers, the knowledge could be applied to the regeneration of human limbs and organs. Scientists know that the shedding is initiated by a fall in the hormone testosterone, a change linked to an increase in day length, and they think oestrogen may be a key cellular regulator. However, much more research on a molecular level is required to unravel what is clearly an intricate process.
To achieve an optimal outcome, Deer Antler Spray is best used first thing in the morning upon waking and nightly before going to bed. Many users find it effective to keep their spray on their nightstands to help keep them to this routine. To amp up your performance and maximize your results, pair our Deer Antler Spray with our Deer Antler Endurance Spray. Deer Antler Endurance Spray helps keep your muscles oxygenated and the lactic acid at bay.
One study published in the Journal of Ethnopharmacology found evidence that use of deer velvet antler may help strengthen joints and bones, reducing symptoms like joint pain associated with osteoarthritis. (10) After rats with osteoarthritic symptoms were given total velvet antler polypeptides from red deer (TVAPL) for 12 weeks, they showed signs of significant reversal in osteoporosis. The researchers found improvements in the rats’ bone weight coefficient (BWC), bone mineral density (BMD), and bone mineral content (BMC). They believe these effects were due to proliferation of cartilage and osteoblast-like cells, in addition to reductions in inflammation due to inhibition of interleukin-1 (IL-1).

I just wanted to let you know that April 29, 2011 I was diagnosed with ALL Leukemia. I just recently, finished my chemo therapy after a 2 year regimen. I have stayed very active though out the 2 years but the drugs were very difficult to tolerate at times. My love is Cycling, I have raced at a high level for many years. I started using the product to help me regain my strength. I have been using the Nutronics IGF-1 for 2 months and my endurance and energy have improved dramatically. I look forward to the continued use and the gains that IGF-1 provides. I appreciate your support.


Currently, IGF-1 is banned by both the World Anti-Doping Agency and the Food and Drug Administration (FDA). However, deer antler spray seems to provide only very small amounts of IGF-1. This is why it’s no longer considered illegal. Insulin-like growth factor is also naturally found in other animal-derived foods, including eggs, milk and red meat. Some experts believe that the amount of IGF-1 obtained from using deer antler products is really not much more than from eating these foods.
Euricoma Longfolia: A shrub found in Southeast Asia that is said by some native cultures to enhance male virility. It has been used unofficially to treat fever, high blood pressure, bone pain, and syphilis, and the limited clinical data about euricoma longfolia that exists suggests it may possibly increase testosterone levels. There is no data about the long-term effects of euricoma longfolia consumption.
It is difficult to analyze the quality of Deer Antler Velvet Spray’s ingredients due to their largely untested nature. Deer velvet contains glucosamine and chondroitin, two key chemicals in the body’s joint health processes that our panel of experts highly recommends. It may also increase estrogen production in the body, which can be both good and bad. In some that may be helpful for correcting existing hormonal imbalances, for others it may create them.
Data is limited. Two studies (n=40 and 168) investigating the efficacy of elk velvet antler supplementation on rheumatoid arthritis found no effect, while a study conducted in people with osteoarthritis (n=53) reported symptomatic relief among participants. The small sample sizes may result in the trials being underpowered to detect effects.25, 28, 29
Aloe Vera Juice: Taken from the pulp of aloe plants and thought by some cultures to have medicinal properties. Aloe is used to treat some skin conditions like sunburn and acne, as well as hemorrhoids, osteoarthritis, and ocular issues. Aloe is safe for topical use or in small doses, however it is not recommended for long-term ingestion or in large quantities. Side effects can include:
I never take a product without doing my research, because it is always good to know what you're putting in your body. I looked at several sources including scholarly journals about many of the ingredients in Deer Antler IGF-1. It is a great product, and has been proven to work without ANY side effects. This product has definitely been helping with my lean muscle gains during my improvement season. It gives me energy before a workout, and it gives me some great vascularity while I'm lifting!
Arthritis Relief: Arthritis is simply the inflammation of a joint. That inflammation is what causes pain of the joint. Reduce inflammation and you reduce pain. That’s why aspirin is so good for some injuries-it reduces the inflammation. There are over 100 kinds of arthritis, almost all of them characterized by discomfort, pain, stiffness, fatigue and swelling of a joint. Unlike medications, which simply dull the pain, Deer Antler velvet brings relief from arthritis because it brings relief from inflammation in a natural way.

One of the leading companies in the world that manufacturers deer antler spray is called Nutronics Labs. According to information posted on their website, they have been making deer antler supplements for two decades. They state that their deer antler products range in concentration/strength from about 25,000ng (nanograms)–200,000ng of IGF-1. According to studies done by Nutronics Labs, deer antler powders appear to be less concentrated with IGF-1. They also may be poorly absorbed compared to deer antler extract.

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]
Bones are connected by joints, which allow us to move with ease. Joint damage can cause pain preventing you from doing the things you once loved. Many conditions lead to joint pain from aging to an untreated sports injury. A quality joint product may help repair existing tissue damage and also promote stronger joints, less susceptible to future degeneration.
Tanejeva also tested the effect of deer antler velvet in athletes running three kilometer races. In the experiment, 50 men ran the distance and their completion time was recorded. Deer antler velvet extract was administered to half of the runners and the participants repeated the race.  The group receiving the Pantocrin completed the subsequent race in a faster average time.

The answer is that deer antler velvet is just another fat burner. Another cell volumizer. Another body-toning shoe. It’s fitness marketing at it’s finest—playing off a goal you desire (gaining more muscle and size) and drawing unsubstantiated and wildly exaggerated claims. There’s nothing miraculous about deer antler spray. And after a closer look at the product, there’s really—well—nothing to it at all.

Deer antlers have been closely linked to IGF-1, which is another term for insulin. This has been well received in eastern medicine as an anti-aging and bodybuilding product. Because it’s also a known natural growth hormone, it’s said to aid in muscle development by enhancing strength and improving recovery time. This is what attracts bodybuilders to this product.
Shake bottle before each use. Take 14 drops under the tongue 3 times per day. Hold for 20 seconds before swallowing for best results. 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!
Immortal Antler Velvet Silver is a less potent form of antler velvet than the Gold. It’s the only all-natural 19:1 extract that contains a powerful blend of growth factors in a naturally occurring matrix, and the only all-natural proprietary matrix to deliver up to 45 mcg’s of IGF-1 per bottle, in addition to the full growth factor matrix. Delivering a full range of growth factors at a 19:1 ratio means it requires 19 lbs of velvet antler tips to create 1 lb of this complete formula. Immortal Antler Velvet Silver is extracted in organic grape alcohol and bottled in miron violet glass for maximum absorption and effectiveness.

One study in men given 1.5g Velvet Antler for 11 weeks noted that intake of Velvet Antler was associated with a greater improvement in peak torque (30+/-21% more than baseline vs. placebo increasing 13+/-15%) and average power (21+/-19% vs. 7+/-12%) as assessed by leg extension; the authors noted that other parameters suggestive of power improvement (such as endocrine improvements or erythropoesis) did not occur and noted that replication is needed.[26] The lack of aerobic improvement noted in this study is contrasted by another study using 2,700mg of Velvet Antler (two doses of 1,350mg daily for 10 weeks) which improved VO2 max by 9.8%, although this study had a remarkably high dropout rate of 44% which precludes conclusions that can be drawn.[27]
The product smells like lemon-scented cleaner and bears a resemblance to murky pond water. I hesitantly tried the stuff and found it surprisingly palatable, with a lemon taste, but not too sour and slightly sweet. The directions say to take 14 drops under the tongue, three times a day, but I stopped after one dose — so I probably don't have a good chance of reaping the benefits, if there are any.
Deer velvet might have an effect due to the hormones it may contain, including testosterone, androstenedione, and dehydroepiandrosterone. Research in rats, using elk velvet antler, suggested the substance may have an androgen-like effect. The antlers are ground into powder, which people take by mouth. Dosage varies by brand, but a recent study used 215 mg per day. Some distributers, though, recommend dosages ranging from 250 mg to as high as 3000 mg (3 g) per day. So talk with your doctor before you start using deer velvet.

Deer antler spray products are not cheap. Expect that buying a high-quality product will set you back about $60–$100 per bottle. When taken as directed, each bottle should last you about one month. You don’t need to refrigerate the spray. However, keep it away from very hot temperatures to preserve the chemical composition of the product. Manufacturers claim that you can start experiencing benefits within 3–4 days. However, results definitely differ from one person to the next.
"Earlier this year, March and April, I purchased a total of 2 bottles of Nutronics Lab’s Starter spray. A tad bit about me: I have a Bachelors in Psychology and a PhD. in life so to speak. I do much research on many different topics, all the way down to these new (terrible research chemicals) that are starting to negatively affect our society. Yes, I am a recovering addict and work with them by the way, so I know much about the brain and it’s physiological aspects. No, I am not a doctor though.
Nutronics Labs Super Max is one of the strongest Antler Velvet on the market. With our 200,000 Nanograms of IGF-1, IGF-2 & other growth factors from the World's Purest Deer Antler Velvet, Super Max helps individuals of all backgrounds train harder, build lean muscle and speed their recovery time, this is by far the strongest and most effective product on the market. This can be used by anyone who wants to achieve optimum IGF levels and a healthy lifestyle.

To determine the effects of deer antler velvet on maximal aerobic performance and the trainability of muscular strength and endurance, 38 active males were randomly assigned in a double-blind fashion to either deer antler velvet extract (n = 12), powder (n = 13), or placebo groups (n = 13). Subjects were tested prior to beginning supplementation and a 10-week strength program, and immediately post-training. All subjects were measured for circulating levels of testosterone, insulin-like growth factor, erythropoietin, red cell mass, plasma volume, and total blood volume. Additionally, muscular strength, endurance, and VO2max were determined. All groups improved 6 RM strength equivalently (41 +/- 26%, p < .001), but there was a greater increase in isokinetic knee extensor strength (30 +/- 21% vs. 13 +/- 15%, p = .04) and endurance (21 +/- 19% vs. 7 +/- 12%, p = .02) in the powder compared to placebo group. There were no endocrine, red cell mass or VO2max changes in any group. These findings do not support an erythropoetic or aerobic ergogenic effect of deer antler velvet. Further, the inconsistent findings regarding the effects of deer antler velvet powder supplementation on the development of strength suggests that further work is required to test the robustness of the observation that this supplement enhances the strength training response and to ensure this observation is not a type I error.

Deer Antler Velvet Extract: This moss-like substance has been used in Chinese medicine for years and is thought to contain a number of compounds that can help with tissue regeneration and repair. The antlers are removed safely and without harm to the animal, and the velvet is thought to have applications for improving circulation, strengthening bone density, and improving male libido. There is very little clinical data regarding the effects of deer velvet, and not much is known about its side effects. Some conditions that may potentially be related to deer antler velvet include:
Tribulus: An extract taken from the Mediterranean puncture vine that some cultures believe to have medicinal values. There is little clinical data surrounding the bio-physical effects of tribulus, however some people take it to enhance athletic performance, sexual ability, and improve circulation. Not much is known about the long-term consequences of tribulus consumption, however there are some indications that it may potentially lead to prostate issues in some men.

Deer antler velvet can play a pivotal role in helping to not only relieve the symptoms of diseases that affect joints, such as osteoarthritis, they can possibly eliminate them entirely. The way it may do this is through the introduction of chondroitin sulfate and glucosamine sulfate into the body. Both of these compounds are abundant in deer antler velvet.
