Currently, IGF-1 is banned by both the World Anti-Doping Agency and the Food and Drug Administration (FDA). However, deer antler spray seems to provide only very small amounts of IGF-1. This is why it’s no longer considered illegal. Insulin-like growth factor is also naturally found in other animal-derived foods, including eggs, milk and red meat. Some experts believe that the amount of IGF-1 obtained from using deer antler products is really not much more than from eating these foods.
Deer antler velvet is used for its purported ability to raise testosterone levels to treat decreased libido (low sex drive), infertility, and erectile dysfunction in men. It is used in combination with other herbs to treat sexual dysfunction and hormonal dysfunction in men and women. It is used to treat conditions resulting from deficient kidneys. Some people use it because of its reputed benefit as an aphrodisiac and muscle strength enhancer. It is also sometimes prescribed to help alleviate withdrawal symptoms in the treatment of morphine addiction.
A Russian study indicated that the amino acids, polypeptides and other compounds found in antler increased the survival rate of mice with cancerous tumors as much as 40 percent. In addition, a study conducted by the East-West Research Institute in Korea found that deer antler velvet appears to increase neutrophil levels in mice, which boost the body’s ability to fight injuries and disease. The mice with tumors lost less weight and suffered lower levels of kidney damage than those treated with drugs.
