What 191-XT Was Designed To Do For YOU!
91-XT gives you the ingredients that make your body a natural anabolic and fat-burning machine. You will pack on more lean body mass and shred more body fat (while retaining your hard-earned muscle tissue), as well as experience enhanced libido, erectile function, and sleep quality.

What Is 191-XT?
191-XT is a premium, all-natural source of orally bioavailable IGF-1 - one of the most anabolic peptide hormones in the human body. Not only does 191-XT increase your IGF-1 naturally, it also boosts other anabolic and fat-burning hormones in your body, including testosterone and growth hormone. And don’t worry, 191-XT doesn’t contain any synthetic, harsh compounds that shut down your endocrine system.

How Does 191-XT Work?
191-XT contains the only orally efficacious source of IGF-1, from deer antler velvet. Normally, your body would breakdown the peptide bonds of IGF-1 if you consumed it orally, but the IGF-1 in deer antler velvet is absorbed intact and rapidly increases plasma IGF-1. 191-XT also contains a blend of natural ingredients that increase your testosterone and growth hormone levels, thereby helping you burn more body fat and build more muscle.


IGF-1… The Next-Level In Muscle Building Agents

I'm sure you've heard of "growth" (GH) before, right? For the past 20 years - it has been the "go to" for bodybuilders, athletes and even Hollywood celebrities.

But did you know, there is a "new sheriff in town" called IGF-1 that just may blow GH out of the water when it comes to building muscle, burning fat, and recovering faster...

The only problem is, until recently, IGF-1 was super tough to get a hold of, and it had to be taken intravenously.

Well - I've got some good news! You can now get an oral version of IGF-1 in a brand new product called 191XT!

191-XT contains the purest natural source of IGF-1 available, coming from the immature tissue surrounding viable deer antlers (which are rich with IGF-1).

Still not sure why IGF-1 kicks ass for building lean size and cutting body fat?

“What Is IGF-1 And Why Is It So Important For Muscle-Building And Getting Lean?”

IGF-1 is a peptide hormone structurally similar to insulin and has strong anabolic and anti-catabolic actions in the human body.

Research demonstrates that IGF-1 is a potent activator of the AKT signaling pathway in muscle cells, which promotes both growth and proliferation.3 Another highly beneficial aspect of IGF-1 is that it blunts skeletal muscle protein breakdown (i.e. it’s anti-catabolic and muscle-sparing).4 

Usually, your body produces small amounts of IGF-1 when growth hormone reaches your liver.

In fact, growth hormone in and of itself is not an anabolic hormone - it’s IGF-1 secreted from elevated growth hormone levels that makes your body anabolic.

This is why 191-XT blows GH out of the water!

Best of all, 191-XT is natural and non-suppressive, meaning you don’t need to cycle it, nor will you get flagged on a drug test.

Benefits Of Supplementing With 191XT

IGF-1 has both local and systemic actions throughout your body, promoting muscle growth and other anabolic processes. Similarly, growth hormone acts throughout your body to mobilize fat tissue so that it can be burned for energy. Testosterone is also one of the most anabolic hormones your body naturally produces and is a primary controller of anabolic and anti-catabolic processes in muscle tissue.

Here's What 191XT Users Are Reporting:

  • Increased levels of anabolic, anti-catabolic, and fat-burning hormones
  • More muscle growth
  • Drastically increased strength, power, and stamina
  • Faster fat loss
  • Enhanced sex drive and feelings of “Alpha” drive
  • Better sleep and more energy throughout the day

The 191XT Ingredient Profile: Naturally Increase IGF-1 & Testosterone!

We all know how important testosterone is for men. If you’re testosterone levels are at rock bottom, you’re not going to be packing on much muscle, nor will you be able to cut off stubborn body fat...Not to mention your sex drive will be nonexistent.

In males, the synthesis of testosterone is controlled by highly intricate interplay between the hypothalamus, pituitary gland, liver, and testes (called the hypothalamic–pituitary–testes axis).

When serum levels of free testosterone drop significantly enough, the hypothalamus creates gonadotropin-releasing hormone (GnRH); GnRH signals the pituitary gland to secrete luteinizing hormone (LH); LH signals the testes to manufacture testosterone. Notice how these hormones ultimately act as a cascade.

Furthermore, IGF-1 and growth hormone secretion are likewise controlled by this exact same HPT axis. Your hypothalamus produces growth hormone-releasing hormone (GHRH), which then tells the pituitary gland to secrete GH in pulses. GH then influences your liver to synthesize IGF-1.

What makes 191XT such a powerful supplement is that it contains ingredients that were designed to act on your HPT axis to increase testosterone, GH, and IGF-1, as well as provide your body with pure IGF-1 from Deer Antler Velvet extract.

Research Behind
The 191XT Formula

Along with Deer Antler Velvet extract, 191XT is loaded with a potent blend of anabolic hormone optimizers designed to help you build lean mass and shed body fat fast!

Here’s the science behind these ingredients:

L-Arginine HCl

L-Arginine HCl is a highly bioavailable, acidic form of L-arginine. Research demonstrates that L-arginine acts on the hypothalamus to promote the secretion of GnRH (gonadotropin-releasing hormone) and GHRH (growth hormone-releasing hormone), which then act downstream to increase testosterone, GH, and IGF-1.1

Epimedium (Epimedium Sagittatum)

Epimedium sagittatum, known commonly as horny goat weed, has been used for ages in Ayurvedic medicine as a natural treatment for sexual dysfunction. Horny goat weed contains a high amount of icariin - a flavonoid that has been shown to block the actions of PDE type-5 enzymes, thereby enhancing blood flow to the genitals.2

Tribulus (Tribulus Terrestris)

Tribulus terrestris has been used in Ayurvedic medicine for many years as a natural testosterone booster and aphrodisiac. Tribulus is an annual herb and member of the Zygophyllaceae family found throughout many tropical and temperate regions of the world, including east Asia, South America, and parts of Europe.

Tribulus contains a specific steroidal saponin known as protodioscin that appears to support natural testosterone levels by elevating serum luteinizing hormone (LH).3

Longjack (Eurycoma Longifolia)

Eurycoma longifolia, also known as Tongkat Ali or longjack, is one of the most popular herbal supplements for increasing low testosterone levels. It seems to work by boosting luteinizing hormone (LH) and follicle-stimulating hormone (FsH) production, two key hormones that stimulate your body to produce more testosterone. In fact, unofficial studies suggest that longjack may elevate natural testosterone levels by upwards of 200% in just six weeks!4
