Introduction

, which are in a similar category to HGH supplements, work by increasing the production of insulin-like growth factor in the body. IGF-1 is similar in structure to insulin, hence the name insulin-like growth factor.

Part of a group of peptides known as somatomedins, IGF-1 is an endocrine hormone that’s mainly produced by the liver and regulates much of the growth-promoting effects of HGH. In simple terms, human growth hormone (HGH) signals the liver to produce IGF-1, which stimulates cell growth, healing, and development throughout the body.

So when IGF-1 levels increase, it’s a sure indicator that HGH levels are increasing as well – and it’s through IGF-1 that HGH delivers many of its benefits.

Normally, IGF-1 production reaches it’s peak during adolescent and pubescence, rapidly decreasing during adulthood. Significant benefits, however, can be achieved by adults who increase IGF-1 levels by using over-the-counter IGF-1 supplements.

IGF-1 supplements encourage the body to increase it’s own production of IGF-1 which can lead to heightened cell growth and development, healing, strengthening of the tissues, and a wide variety of other “anti-aging” benefits, including:

  • An increase in lean muscle mass
  • Faster metabolism and fat burning
  • Strength and endurance gains
  • A stronger immune system
  • Speedier recovery and healing time
  • An increased sex drive
  • Better cognitive function

Common Ingredients Used in IGF-1 Supplements

The ingredients found in IGF-1 supplements are often similar to those found in HGH products, and in fact, most HGH supplements work by raising IGF-1 levels. Some of these ingredients include things like:

  • Amino acids
  • Colostrum
  • Deer Antler Velvet
  • GABA

Not surprisingly, these types of supplements are a popular choice among bodybuilders, professional athletes, and people looking for anti-aging benefits.

L-Ornithine and L-Arginine

L-arginine is a semi-essential amino acid and has a number of important functions. Two of these functions include stimulating the secretion growth hormone IGF-1.

L-ornithine has also been proven to increase the production of HGH. L-ornithine is an amino acid that can increase blood flow, muscle performance, and muscle growth.

Studies have shown that L-arginine combined with L-ornithine increases HGH and IGF-1 levels.

One 3-week study involved athletes who were randomly given either a combination of L-ornithine and L-arginine, or a placebo. Researchers observed that the athletes who were given L-ornithine and L-arginine saw significant increases in both growth hormone IGF-1 serum levels. (2)

The study showed that when taking l-arginine with l-ornithine you can expect to see an increase in HGH and IGF-1 after intense resistance training.

Colostrum

Colostrum, which is a fluid found in the breast milk of mammals (including humans) during late pregnancy or the days following birth. Colostrum promotes the production of human growth hormone.

Colostrum contains insulin-like growth factors, which are technically by-products of HGH. In fact,  IGF-1 levels are measured  to evaluate the amount of HGH produced in the body.

Bovine colostrum is nearly identical to human colostrum. However, bovine colostrum contains more growth factors (i.e. growth-stimulating hormones) than human colostrum.

IGF-1 is believed to be responsible for the health-enhancing effects of HGH. Colostrum provides a number of excellent benefits, such as boosted immunity, enhanced healing, increased muscle mass, stronger bones and anti-aging.

Deer Antler Velvet

Another common ingredient used for raising IGF-1 levels is deer antler velvet. Once banned by the World Anti-Doping Agency, deer antler velvet contains several important growth factor components, including IGF-1.

However, because IGF-1 is known to aid in the regeneration of cartilage, tendons, and joints, many athletes continue to use it. In particular, it is used  following strenuous workouts and grueling competitions.

IGF-1 has been shown to accelerate healing and recovery, and a 100% legal way to experience this for yourself is to take a supplement containing deer antler velvet.

GABA

According anecdotal reports found on various bodybuilding websites, GABA supplements are claimed to boost the production of HGH. This is certainly true for GABA that’s naturally produced by the body, but evidence also supports the idea that oral GABA supplements can trigger HGH and IGF-1 production as well.

Men participating in a study at Virginia’s Shenandoah University were given either GABA supplements or a placebo prior to engaging in resistance training exercises. Researchers found that GABA increased the total amount of growth hormone the subjects produced as a result of training by a whopping 480 percent! (3)

The researchers concluded that ingested GABA supplements can significantly elevate resting and post-exercise growth hormone levels.

In another study, participants receiving GABA supplementation showed significant improvement in physical fitness, vitality, and mental function. IGF-1 levels within the GABA group also increased compared to the levels before intake. Additionally, there were no adverse effects or clinically concerning changes were observed. (4)

Additional research has also shown that GABA supplementation does indeed increase IGF-1 levels. (5)

  1. I’ve been using Pituitary Growth Hormone and it makes a 48 year-old man like me feel like I’m in my 20s again. No BS. I’m on my 2nd purchase and this time I got the 3 for 2 deal. More energy, better mood and motivation, my joint and back pain are pretty much gone. Joints feel smooth and move way better. For sure feel a testosterone boost. Muscles feel bigger and losing weight.
