The growing market has bred plenty of competition. A company called Now Foods is now making deer antler velvet lozenges. GNC just started selling deer antler velvet capsules called New Vigor from a company called Vitalast and Amazon.com has more than 30 products will deer antler velvet in it including the raw powder from New Zealand, where the most coveted deer velvet is harvested.
Nutronics Labs patented delivery system allows faster delivery and longer duration of nutrient action, making it superior over tablets, capsules and powder products.

Currently, IGF-1 is banned by both the World Anti-Doping Agency and the Food and Drug Administration (FDA). However, deer antler spray seems to provide only very small amounts of IGF-1. This is why it’s no longer considered illegal. Insulin-like growth factor is also naturally found in other animal-derived foods, including eggs, milk and red meat. Some experts believe that the amount of IGF-1 obtained from using deer antler products is really not much more than from eating these foods.
In another randomized, double blind, placebo controlled experiment (Broeder, 2004), 38 males, all of whom were experienced weightlifters, entered a 10 week strength training program. Those who took deer antler velvet experienced an increase in peak torque and average power relative to the placebo group. They also experienced unexpected improvements in aerobic performance.
In a randomized, placebo controlled test in 2004, researchers at the University of Alberta, Canada, placed 18 males from the Edmonton Police Force into a 9 week strength training program. The results showed that deer antler velvet increased the strength and endurance of the subjects relative to the control group. The researchers found that use of deer antler velvet significantly increased blood plasma testosterone levels.
