Published research has shown that IGF-1 can produce similar results to growth hormone. The catch? If you do the math from the study, a 150-pound man (that’s a pretty small guy, so a bigger man would need more) would have to take more than 25 million nanograms just to experience the growth hormone-like effects of more muscle, less fat, and faster recovery.
Dr. Low Dog also reports that a chronic wasting disease in deer, elk and moose is the only recognized prion (infectious protein) disease of wild animals and has been found in 15 states and two provinces in Canada. (Prion diseases in wild animals are similar to bovine spongiform encephalopathy, better known as mad cow disease, in cattle.) No known cases of neurological disease have been seen in humans who have taken deer antler velvet supplements, but a 2009 study sponsored by the National Institutes of Neurological Diseases and Stroke and the U.S. Department of Agriculture concluded that the possibility remains.
If you have any existing medical condition that requires taking medication, always consult your physician before taking any new products. Discuss if deer antler spray will be safe for you to use if you have a history of serious hormonal problems, heart disease, liver or kidney disease, or any other serious condition. It’s also not wise to stop taking any medications you’ve been taking or to end physical therapy sessions/exercises because you’ve started taking deer antler spray. Always follow up with your doctor or therapist if you have questions about changing your recovery plan regarding an injury or illness.
In an experiment (Gerard, 2004) conducted to study muscle damage and repair, 20 males ran for 35 minutes on a downhill treadmill. The participants, who were not trained runners, were pre-treated with deer antler velvet or a placebo 14 days prior to the run. The subjected treated with deer velvet showed that their creatine kinase levels, a marker of muscle damage, was significantly lower than the control group. Also, muscle soreness on average was reported to be gone 24 hours before subjects in control.
A systemic review on human interventions makes note of a study conducted on patients of osteoarthritis (Edelman et al. 2000; cannot be located online) which found improvements in joint pain symptoms relative to baseline in the Velvet Antler group and not placebo, although a lack of information on blinding and randomization precludes results that can be drawn from this study.
