The FDA considers deer antler spray (or deer antler velvet) to be a dietary supplement. This means it doesn’t need to be extensively studied and regulated like medications. For this reason, it can be hard to tell what the actual concentration of active ingredients or IGF-1 is in various supplements. Plus products can differ quite a bit from one brand to another in terms of their purity and effectiveness.
There is some evidence that deer antler spray may work for improving performance and physique. However, it seems that an individual needs to take very high doses in order for these benefits to occur. In studies where the supplement was effective, injections of very concentrated extracts were used. Injections may be the most effective, and likely the only, way that deer antler works. This is because IGF-1 is mostly destroyed when it passes through the digestive system. Because of this, swallowing deer antler supplements would practically be useless.
I recently ordered IGF-1 Plus Maximum in order to gain results from my physical therapy workouts. Since using this product, I am not only able to do harder workouts, but I also have increased muscle mass. Besides these benefits I have experienced improvement in my wound healing! Areas that repeatedly break down are showing increased healing like never before. My hands, which are severely scarred, have more flexibility. I look forward to the many benefits that may come from using IGF-1. Thank you Rick Lentini!

Bottom line: Rogol says it’s “extremely unlikely” that deer antler in any form could offer athletes a boost. “Deer antlers do contain growth factors,” he explains. But it’s a huge leap of faith to talk about an extract doing anything beneficial for human beings, whether it’s slowing aging, developing muscle, or repairing tendons, he adds. Opinions like Rogol’s are one reason the FDA and anti-doping agencies haven’t yet taken steps to ban deer antler products that contain IGF-1.
In Russia, Korea and China, deer antler velvet is widely used by athletes to enhance performance. In the United States, more and more athletes are looking to deer antler velvet as a training aid, a promoter of recovery after physical activity and injury, and possibly an injury preventative. Deer velvet could improve athletic performance in many ways, for example by assisting strength and endurance, by supporting the oxygen-carrying capacity of the blood, by facilitating minor tissue damage, and by boosting the immune system.
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.
