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]

Muscle Builder* - Some "experts" make bold claims that it builds muscle. They compare it to synthetic anabolics that give many athletes who dope an advantage over the competition. This is folly claim that has no backing from direct research or research into other associated fields that would be relevant to deer antler spray. Only one thing will build muscle: proper resistance training. Make the right choice and get to work.*
"Unlike steroids, which are small, cholesterol-based hormones, protein-based hormones or growth factors can easily be destroyed," he wrote in an email. Cohen guesses that even if you consume high levels of IGF-1, most if not all of the substance would be destroyed after hitting the acid in our stomach and before entering the blood system, which is how compounds we ingest reach the muscles. "This is also why you have to inject insulin instead of just eating insulin pills," he added.
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.
