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.
Generally researchers agree that deer antler velvet protects, strengthens and restores the body's functions that are out of balance. In other words, it can act as an adaptogen on the human body, helping where it is needed. Studies suggest that deer antler velvet may have beneficial effects related to: increases in muscular development, strength and endurance; improved recovery; prevention and reduction of inflammation; improvement of sexual health; reduction in blood pressure; improvement in bone and joint health; stimulation of the immune system; and more.
While Lentini admits sales have picked up, he says he's been hurt by the perception in the recent baseball letter, which told players that deer antler velvet could be contaminated with methyltestosterone, a banned steroid. The connection is based on the fact that David Vobora tested positive for the steroid after using antler spray. He won a $5.4 million judgment against the company that made the spray.
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).
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. 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.
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.
