NutraKey Red Deer Antler Review
NutraKey promises its product Red Deer Antler increases testosterone, enhances muscle performance, increases energy, and stimulates growth hormone levels.
They also say Red Deer Antler is pharmaceutical grade, free of yeast, dairy, gluten, and artificial ingredients.
Can NutraKey Red Deer Antler do all of this with one ingredient? I decided to find out.
The Single Ingredient
NutraKey Red Deer Antler is simply comprised of New Zealand red deer antler velvet. Deer Antler Velvet is taken from the antlers of young deer before they become hard.
In one study, researchers compared New Zealand deer antler velvet (NZDAV) to a placebo. Subjects took 1350 mg of NZDAV twice a day, once in the morning and again at night. After NZDAV
supplementation subjects saw a significant decrease in body fat, fat weight, and trunk-to-limb fat weight ratio. The NZDAV group also saw significant improvements in the bench press, the squat, and aerobic capacity. 
If used in the recommended dosage, NutraKey Red Deer Antler provides 500 mg of deer antler velvet a day. This isn’t enough to see results as strong as found in this study.
I wasn’t able to find any studies connecting deer antler velvet to growth hormone production. Deer antler velvet does contain growth factor IGF-1, which can increase HGH levels. However, the amount of IGF-1 contained in deer antler velvet is determined by what the deer was fed and how old it was. So it’s hard to know how much IGF-1 is contained in deer antler velvet supplements and if it will be effective. 
There are no recorded side effects of NutraKey Red Deer Antler.
Not enough is known about deer antler velvet to know if the ingredient itself has any possible side effects.

To Wrap Up
It looks like NutraKey Red Deer Antler has the potential to increase muscle mass and performance. However, there is no research to back up claims of rising testosterone or HGH levels.
If you are looking for a way to enhance your muscle performance, this could be a good and inexpensive route for you. However I wouldn’t recommend this product for any other uses.
