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.

Deer antler spray is a supplement. It’s made from the immature tissues surrounding bone and cartilage found inside the tips of live deer antlers. The antlers naturally contain IGF-1. This helps them to grow rapidly. The tissue is taken from the deer antlers before they fully grow and harden. Then it’s flash-frozen to make supplements. (3) Farmed North American elk or wapiti (Cervus canadensis) and the European red deer (Cervus elaphus) are the main sources of antler for commercial use. The animals are not harmed in the process of extracting the substance from their antlers. Deer antler products are found in pill, powder or spray forms.

Deer antler velvet can play a pivotal role in helping to not only relieve the symptoms of diseases that affect joints, such as osteoarthritis, they can possibly eliminate them entirely. The way it may do this is through the introduction of chondroitin sulfate and glucosamine sulfate into the body. Both of these compounds are abundant in deer antler velvet.
