I know of no scientific evidence to support any of the marketing claims made for these supplements. I discussed your question with Tieraona Low Dog, M.D., an internationally recognized expert in the fields of integrative medicine, dietary supplements and women’s health, and an authority on botanical medicine. She explains that IGF-1 in the velvet promotes rapid growth of the antler. Dr. Low Dog notes that the two studies examining the effects of deer antler velvet supplements taken by athletes have yielded conflicting results. One showed some improvements in endurance and knee strength in weightlifters, but the other found no differences in rowers after 10 weeks of supplementation.
S.W.A.T.S. Fitness and Performance was a dietary supplement company that sold deer antler spray and other products. The owners began distributing their products to NCAA and NFL athletes in 2008. The controversy initially started in March 30, 2009 when Alabama athletic officials sent a cease-and-desist letter to the company's owner that stated: "Refrain from using current student-athletes to endorse products. Refrain from contacting current student-athletes. Refrain from giving or selling products to current student-athletes."  The letter was then sent again in 2012.
Researchers believe that the imbalance between cartilage erosion and regeneration in osteoarthritis suffers is caused by a lack of glycosaminoglycans. Glycosaminoglycans play a vital role in the structural integrity of cartilage. The compound appears to inhibit enzymes that deplete cartilage nutrition. Chondroitin sulfate molecules are long chains of sugars and sulfur that create tiny spaces filled with fluid. These spaces protect and cushion joints.
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.)
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.
Much of the research and its conclusions on deer antler velvet has been done 15 to 70 years ago in many other countries around the world. There are experts with relevant degrees in nutrition and doctors who have spent a great deal of time researching this supplement to better understand its benefits for their own clients and patients. As well as educating us about the many reasons to use it.
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.
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*.
