The Best IGF-1 Supplements 2021

Introduction

IGF-1 supplements, 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.

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:

Pituitary Growth Hormone

Pituitary Growth Hormone (pGH) from Anabolic Research is our top-recommended IGF-1 supplement, and it’s by far the best we have researched and tested to date. Formulated to trigger lean muscle growth, increased strength and stamina, weight loss, and improved cognitive function, Pituitary Growth Hormone is the ultimate in hormone optimization.

Pituitary Growth Hormone was designed to naturally stimulate anabolic activity and metabolic enhancement,  and it’s a highly-effective general performance supplement for promoting lean muscle mass and athletic performance. pGH stimulates the metabolism in a way that promotes lean tissue growth with minimal body fat gain, while improving many other aspects of fitness, including deeper sleep, faster healing and recovery, and elevated mood.

Pituitary Growth Hormone is one of the most efficient and potent products I’ve personally tested, and most other supplements don’t even come close. If you’re looking for massive gains in athletic performance and physical fitness, look no farther than Pituitary Growth Hormone.

WARNING: If you are a professional athlete or otherwise subject to testing by the IOC or other sports governing body, this product may cause you to test positive for performance enhancing drugs.

GenF20 Plus

GenF20 Plus is another high-quality product manufactured by Leading Edge Health. Like HyperGH 14x, GenF20 Plus takes advantage of a two-pronged approach to raising growth hormone levels by combining a power-packed pill with a highly efficient oral spray, using the best of both worlds to safely and effectively increase IGF-1 production.

GenF20 Plus contains an exact formula herbal extracts, amino acids, and other growth factors that research has shown to produce effects such as: muscle gain, stronger bones, increased energy and motivation, a more youthful appearance, and many other benefits. In fact, after conducting a 12 week double-blind study, researchers noted that GenF20 Plus increased IGF-1 levels by 28% after just 12 weeks. 

I’ve used GenF20 Plus and know first-hand what an amazing, proven IGF-1 supplement system it is. With continued use, it can make you look and feel 10, 15, even 20 years younger. Highly recommended.

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
• Vitamins and/or minerals
• Herbal extracts
• Colostrum
• Pituitary extract
• GABA

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.

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