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.
A study using a mouse model published in Skeletal Muscle by Clara De Palma, et al found that deficient NO signaling impairs skeletal muscle growth.[2]
Antioxidants in the formula lower free radicals to reduce oxidative stress, promoting repair and healing and strengthening immunity. In addition, anti-inflammatory agents could decrease swelling and pain to speed up muscle recovery.
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.[3]
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.[4]
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.[5]

What Do the Reviews Say?
On the whole, while the ingredients have some limited support for their ability to increase IGF-1 and testosterone, the dosages are too low to produce significant effects.

Feedback varies on social media sites like Reddit and TikTok, and some users did not get the results they hoped for. On Trustpilot, the total rating from 8 users is 2.7 and there are several complaints.

My skin is getting softer, and I feel younger. And my workouts have been intense. My knees quit aching, and my speed and agility are increasing again. Now my problem is controlling how HIGH I jump!

In my opinion, this company is horrible. They have shady business practices including calling you to scam you to buy more and more from them.
With their hard-sell approach, horrible customer service, and terrible management, you’d do well to avoid them. Just do a search for the company name and “scam.

Q: Does Primal Muscle 191xt work
A: While there is some support for the ability of Deer Antler Velvet and other ingredients to increase 191xt to some extent, dosages would have to be much higher to have any real impact.

The small increase in hormone levels and enhanced circulation could provide some sexual libido and erectile function benefits.

A: There are other deer antler velvet-based sprays on the market, as well as capsules, and some include other similar ingredients. While the formula is not unique, the ingredient dosages in Primal Muscle 191xt are low compared to some of the competing brands and the price is expensive for the market.
