Nutronics Labs was the very first company to turn deer antler extract into a liposome spray over 25 years ago. Since then, many competitors have entered the marketplace touting various claims that are misleading and completely untrue. Don’t be fooled by these other brands selling inferior products. Despite the widespread use of supplements containing IGF-1, we remain the only manufacturer of best deer antler spray to date that has had clinical trials done on their own products.
