Deer antler spray — a supplement commonly used in the fitness and sports industries that has a long history of use in Eastern medicine — is pretty much as strange as it sounds. Derived from the tissue found inside deer antlers, it’s reported to work by providing IGF-1 (insulin-like growth factor), a natural growth hormone found inside the human body that has potential to increase muscle mass and support recovery from injuries.

An acute dose of 2,000mg/kg Deer Velvet Antler to rats (human equivalent dose of 320mg/kg) has failed to show toxic signs over 14 subsequent days of observation, and a 90 day trial with daily dosing of 1,000mg/kg did not show any significant toxicological symptoms of haemotological signs; a decrease in liver weight was noted in males, but under histological examination it appeared to be benign.[38] Another rat toxicological study using 10% of the diet as Deer Velvet Antler during gestation and after birth noted that there were no apparent teratogenic effects on the rat pups and that serum AST (indicative of liver damage) was actually decreased 50% relative to control with no effect on γ-GT (another liver enzyme).[30]


A Russian study indicated that the amino acids, polypeptides and other compounds found in antler increased the survival rate of mice with cancerous tumors as much as 40 percent. In addition, a study conducted by the East-West Research Institute in Korea found that deer antler velvet appears to increase neutrophil levels in mice, which boost the body’s ability to fight injuries and disease. The mice with tumors lost less weight and suffered lower levels of kidney damage than those treated with drugs.
My name is William Gucciardo. I am fifty-four years old and have been exercising and taking nutritional supplementation for many years. I was recently introduced to IGF-1, and have been taking it for three weeks. Although I have been working out six days a week for the past several years, I have recently noticed an increase in upper body muscle tone and overall strength and endurance. I have also noticed that minor stiffness that I daily experienced upon arising in the morning is gone. My body feels stronger with an overall feeling of well being. I can only attribute these changes to the addition of IGF-1 to my supplementation program, as this is the only change that I have recently made. I do not know what further benefits I will receive from taking IGF-1 daily. If you are willing to try something new with the possibility of improving your health and well being, I would recommend trying this product.
Tanejeva also tested the effect of deer antler velvet in athletes running three kilometer races. In the experiment, 50 men ran the distance and their completion time was recorded. Deer antler velvet extract was administered to half of the runners and the participants repeated the race.  The group receiving the Pantocrin completed the subsequent race in a faster average time.

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)
