Deer Antler Velvet Spray has been tested and results show that this is safe. It doesn’t contain the controversial Human Growth Hormone, but it offers the same benefits. This doesn’t need a prescription. However, the site states that some have experienced mild stomach pains. While this is considered a supplement, doctors still advise you to go in for consultation because this product is surrounded with controversy and isn’t well accepted by the medical community.
A study (Yudin and Dobyrakov, 1974) on the effect of deer antler velvet extract on the static load-bearing capacity of subjects found that those who took the extract increased the time of work by 2-4 seconds compared to the control group. In tests of dynamic work using a veloergometer, the subjects who took the extract increased the work output 4 to 5 times more than the control group.
Aloe Vera Juice: Taken from the pulp of aloe plants and thought by some cultures to have medicinal properties. Aloe is used to treat some skin conditions like sunburn and acne, as well as hemorrhoids, osteoarthritis, and ocular issues. Aloe is safe for topical use or in small doses, however it is not recommended for long-term ingestion or in large quantities. Side effects can include:
Although the site states that this product shouldn’t cause ill side effects, most western medical practitioners would dissuade you from taking this because the components found in deer antlers haven’t been approved by the FDA. More importantly, IGF-1 has been proven unstable. So, it’s best to speak to your physician, especially when you’re currently taking other forms of medication.
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)
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.
