IGF-1 can help slow this aging process down by increasing the telomere length of our DNA. Telomeres are a protective "cap" at the end of each strand of our DNA which prevents the DNA from becoming damaged. DNA becomes damaged as the telomeres grow shorter with age. As more DNA strands become damaged, cells in our bodies can no longer function properly which results in many medical conditions, diseases, and even death. This is how IGF-1 can help longevity. It does this by promoting healthy DNA strands to keep our cellular functions optimal.
The harvesting of deer antler velvet can be a painful process, as the velvet tissue contains an abundance of nerves and bleeds profusely if cut or removed. Dr. Low Dog says she has no problem with harvesting velvet from deer killed for food, but is concerned that shortcuts will be taken should demand for the supplements continue to grow. She notes that the United Kingdom has banned the removal of deer antler velvet under its welfare-of-livestock regulations, unless the antlers have been damaged or most of the velvet has been shed.

The company has found that powders have only about a 15–20 percent absorption rate of IGF-1. This is due to how the digestive system breaks down the powder. Nutronics states that their “proprietary sublingual spray delivery system” is superior to many competitors because it offers “enhanced bioavailability” of IGF-1. They also point out that “it is not the milligrams of Deer Antler Velvet in the product, it’s the content of IGF-1 and other Growth Factors in Deer Antler Velvet, that makes the difference.”(6)
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.

Deer antler velvet's effects on cell growth and repair have been investigated in several areas. Deer antler velvet may be a natural source of hormones for those seeking aid to muscle growth and development. Research has identified various growth factors in deer antler velvet including IGF-1 (insulin–like Growth Factor-1), IGF-2 (insulin–like Growth Factor-2), and EGF (Epidermal Growth Factor).
