Now, you’ll probably read a lot about the power of IGF-1 in many reports about Ray Lewis. And while it’s true that IGF-1 is illegal in man-made form, let’s not mistake illegal products (because they are synthetic) with guaranteed amazing results. IGF-1 can have a significant impact on your body, but it’s not that easy to get the levels you need from deer antler. In fact, given what’s in a typical bottle, it is damn near impossible.
Deer antler velvet is supposed to help you build muscle. It allegedly elevates levels of IGF-1, an important hormone that helps you pack on mass. As “side effects” you also should see improvements in strength and endurance. And some products even claim it speeds recovery, which is why it was linked to Ray Lewis who earlier suffered an apparent season-ending injury, and yet has played and performed at a high level in the playoffs.
A growing trend in western medicine is the proliferation of influences from ancient eastern medicine. Over 2,000 years ago, the Chinese were administering deer antler velvet to treat conditions ranging from serious illnesses to lack of sexual desire. After closely examining the wide range of health benefits deer antler velvet promotes, it's no wonder why the Chinese used it as a medicine for thousands of years.
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.
Velvet antler in the form of deer antler spray has been at the center of multiple controversies with professional sports leagues and famous athletes allegedly using it for injury recovery and performance enhancement purposes. In mid-2011 a National Football League (NFL) player successfully sued a deer antler velvet spray manufacturer for testing positive for methyltestosterone in 2009 for a total amount of 5.4 million US dollars. In August 2011, Major League Baseball (MLB) added deer antler spray to their list of prohibited items because it contains "potentially contaminated nutritional supplements." 
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.
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. 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).
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.
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.
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!

In another randomized, double blind, placebo controlled experiment (Broeder, 2004), 38 males, all of whom were experienced weightlifters, entered a 10 week strength training program. Those who took deer antler velvet experienced an increase in peak torque and average power relative to the placebo group. They also experienced unexpected improvements in aerobic performance.
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*.
However, calcium and phosphorus levels (which are important for bone growth) did not differ among groups. Overall, the researchers concluded that “our results seem to support a role for dietary supplementation of EVA on growth and bone development in this model.” (9) However, it’s important to point out that this is a very high dose. It’s significantly above what most would take in supplement form.
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.
Research in Korea, New Zealand and China has shown that deer antler velvet can stimulate the immune system. Extracts of deer antler velvet were variously shown to increase macrophage activity, stimulate the production of lymphocytes and increase the number of red and white blood cells. Each of these effects may directly complement the body’s ability to resist or fight disease and so promote and maintain health and an associated feeling of well being.
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.
Repeated studies have been conducted on the interactions of Velvet Antler and hormones, and all studies have found that this supplement has failed to increase circulating hormone levels. One study found a highly variable increase in power output, which is antagonized by another study suggesting no significant increase in power. For the purposes of performance enhancement, the evidence does not currently support Velvet Antler as a supplement.
Deer antler velvet's effects on cell growth and repair have been investigated in several areas. Deer antler velvet may be a natural source of hormones for those seeking aid to muscle growth and development. Research has identified various growth factors in deer antler velvet including IGF-1 (insulin–like Growth Factor-1), IGF-2 (insulin–like Growth Factor-2), and EGF (Epidermal Growth Factor).
