How Does Primal Muscle 191xt Work?
The primary goal of Primal Muscle 191xt Spray is to increase levels of the hormone IGF-1, with deer antler velvet and other ingredients. Possible benefits include enhancing muscle mass, strength, tone, and recovery, speeding up the metabolism, promoting fat and weight loss, improving physical performance, and enhancing well-being.
A review by Anastassios Philippou, et al in the publication in vivo discussed the role of IGF-1 in skeletal muscle physiology.
According to the University of Virginia endocrinologist. Alan Rogol, M.D., the IGF-1 present in deer antler velvet is unlikely to offer many advantages as a supplement or spray:
You can’t eat this stuff in a pill, because the digestive system will destroy it.” In the form of a spay under the tongue, he said it could be absorbed, “But the amounts would be vanishingly small. In humans, I can’t believe it could be effective.
Some of the Primal Muscle 191xt Spray ingredients may increase testosterone levels, which could boost sexual libido and stamina, increase energy, promote fat-burning and weight loss, and increase muscle mass and strength.
Some ingredients in the spray could stimulate the production of nitric oxide in the body, improving circulation and vasodilation. As we said in our review of Power Upp, this sends added oxygen and nutrients to the muscle which could increase mass and strength. It may also promote harder erections by sending added blood flow to the penis.
Primal Muscle 191xt Ingredients?
In addition to Deer Antler Velvet, some of the other primary active Primal Muscle 191xt Spray ingredients include:
Tribulus Terrestris – There’s some evidence that this plant may increase growth hormone levels as well as testosterone. As we said in our review of Enduro Lean, it may boost mule mass and strength, improve physical performance, and enhance sexual libido.
A 6-week study of healthy men trained in CrossFit published in Nutrients by Diego Fernández-Lázaro, et al concluded that supplementation with Tribulus Terrestris may help mitigate fatigue and increase testosterone levels but it did not improve performance or impact body mass.[1]
Niacin – Also called Vitamin B3, niacin enhances circulation by boosting nitric oxide synthesis, and the added nutrients and oxygen to the muscle could build muscle and increase strength. It may also support heart, brain, and nervous system health and function.
A study analyzing American population-based nutritional survey data published in the Journal of Nutrition, Health, & Aging by S Xiang, et al concluded that supplementation with niacin may improve body composition and glucose homeostasis in adults over 40.[2]
L-Arginine – This amino acid could boost levels of growth hormone and IGF-1, for possible benefits to physical performance and muscle development. It also increases the production of nitric oxide in the body, improving circulation. The added transport of oxygen and nutrients to the muscles could heighten mass and strength.
A 4-week study of water polo players published in Oxidative Medicine and Cellular Longevity by Jessica Gambardella, et al concluded that l-arginine supplementation is safe and may improve oxidative metabolism for better physical fitness potentially.[3]

Disappointed and Still Waiting Results
Used it consistently for a month. No noticeable changes in performance or recovery. Just experienced mild headaches. Totally underwhelmed by the hype.
No Muscle Gain After Weeks..!!
I followed the instructions daily, but saw no improvement in strength or size. Felt like a waste of money. Wouldn’t recommend it to serious lifters.
