Unfortunately, the potential problems with IGF would seem to negate any of these theoretical benefits. It has been shown that improper use of hormones such as dehydroepiandrosterone (DHEA), androstenedione, and human growth hormone may increase the risk for development of prostate cancer or promote the growth of existing prostate cancer by raising IGF-1 levels. Therefore, men who are taking supplements with IGF in it (or those that raise IGF levels) could theoretically be putting themselves at an increased risk for prostate cancer. Again, it hasn’t been rigorously studied so it’s impossible to know for sure, but if you have any risk factors for prostate cancer, it’s probably best to avoid taking this supplement.
Velvet antler is the whole cartilaginous antler in a precalcified growth stage of the Cervidae family including the species of deer, elk, moose and caribou. Velvet antler is covered in a hairy, velvet-like "skin" known as velvet and its tines are rounded, because the antler has not calcified or finished developing. Velvet antler preparations are sold in China as part of Traditional Chinese medicine, and in the United States and some other countries as a dietary supplement.
Ultimately it is too early in the testing process for our experts to be able to recommend Deer Antler Velvet Spray as either safe or effective as a joint health supplement. It is more possible it is effective as a male libido enhancer than as a nutritional supplement, and there is little reason to think that Deer Antler Velvet Spray could do much to actually contribute to the health of the body’s connective tissues. It does not have any anti-inflammatory agents to fight joint pain, there is only the smallest amount of glucosamine and chondroitin, and finally the potential for negative consequences is too high for our team to be able to encourage our readers to consume this product.
