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.
The FDA considers deer antler spray (or deer antler velvet) to be a dietary supplement. This means it doesn’t need to be extensively studied and regulated like medications. For this reason, it can be hard to tell what the actual concentration of active ingredients or IGF-1 is in various supplements. Plus products can differ quite a bit from one brand to another in terms of their purity and effectiveness.
Deer velvet might have an effect due to the hormones it may contain, including testosterone, androstenedione, and dehydroepiandrosterone. Research in rats, using elk velvet antler, suggested the substance may have an androgen-like effect. The antlers are ground into powder, which people take by mouth. Dosage varies by brand, but a recent study used 215 mg per day. Some distributers, though, recommend dosages ranging from 250 mg to as high as 3000 mg (3 g) per day. So talk with your doctor before you start using deer velvet.
