There must be a reason to is use and a booming world industry that garners the attention of several researchers and scientist in many countries. Modern understanding has greatly advanced our knowledge of velvet antler. We know by its composition and the knowledge of the structure and function of the plenitude of constituents which work together, like a symphony, to create an efficacious supplement that yields a multitude of benefits.
Adaptogen: Adaptogens are natural metabolic regulators that increase a person’s ability to adapt to environmental factors-like pollution, smoke, stress, toxins etc. and to avoid damage from those factors. In other words, adaptogens literally help your body “adapt” to the environment without any side effects. If you’re living in the real world, with external or internal stressors, adaptogens help your body change in order to cope with the stressors.
One study published in the Journal of Ethnopharmacology found evidence that use of deer velvet antler may help strengthen joints and bones, reducing symptoms like joint pain associated with osteoarthritis. (10) After rats with osteoarthritic symptoms were given total velvet antler polypeptides from red deer (TVAPL) for 12 weeks, they showed signs of significant reversal in osteoporosis. The researchers found improvements in the rats’ bone weight coefficient (BWC), bone mineral density (BMD), and bone mineral content (BMC). They believe these effects were due to proliferation of cartilage and osteoblast-like cells, in addition to reductions in inflammation due to inhibition of interleukin-1 (IL-1).

Russian and Japanese researchers have conducted experiments using deer antler extract and found that it appears to lower blood pressure in both human subjects and laboratory animals. A series of clinical case studies (Albov, 1969) were conducted in which the effects of Pantocrin on cardiac patients were assessed. In one test involving 32 subjects with high blood pressure caused by cardiac disease, early onset menopause or obesity, blood pressure was lowered in 81% of patients. In another study involving 13 patients with hypotension caused by disorders of heart muscle activity, blood pressure was lowered for 84% of patients.
Research has been conducted on the potential use of deer antler velvet for healing of wounds. In Russia (Arapov, 1969), Pantocrin was administered to patients with surgical and internal wounds. The study reported that there were a number of positive effects, including the normalization of arterial pressure, reduction in surgical complications, and becoming active quicker. In tests on rats (Wang, 1985), bone fracture repair was accelerated. A recent study by Bubenik found that antler helped heal epidermal wounds in rats. In another study by Takikawa, et al., researchers reported observing new bone formation following experimental whiplash injuries in rabbits. Pretreatment in rats reduced cell degradation and improved recovery times from extreme temperature and electric shock exposure. 
Even sellers of deer antler products doubt that the products could deliver IGF-1. "IGF-1 is very unstable," Dean Nieves of Florida-based Bio Lab Naturals told the Baltimore Sun. "It could not exist outside of a very controlled environment." Nieves' company therefore markets the product as a nutritional supplement. "It is just packed with nutrients," he said.
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).
